| ### Issue you'd like to raise.
Hi,
Not sure if someone is facting this "issue" or is something wrong I'm doing.
So far .. I read, GPT 3.5 turbo and later should be used with "chat_models" instead of "models". While testing the "summary" chaing (map_reduce). I noticed that using "model" llm it does indeed run in parallel, but using chat_model does run in sequence.
From the src in langchain .. I saw:
[langchain][chains][combine_documents] map_reduce.py
> map_results = await self.llm_chain.aapply(
# FYI - this is parallelized and so it is fast.
[{**{self.document_variable_name: d.page_content}, **kwargs} for d in docs],
callbacks=callbacks,
)
And tracing the execution down
**AzureOpenAI chat_model**: it will execute a for loop and wait for the response. Multiple API calls to the endpoint
> results.append(
self._generate_with_cache(
m,
stop=stop,
run_manager=run_managers[i] if run_managers else None,
**kwargs,
)
)
**AzureOpenAI model**: (aka completion) ... it generates a single call with all the prompts.
> response = completion_with_retry(self, prompt=_prompts, **params)
And here are my outcomes:
- Using ChatModel (azure) ... it works as expected, following the prompt and creating the expected output, but in a sequential execution.
- Using LLM Model (azure - aka completion) ... it runs in parallel, but the "summaries" are not correct, it "creates ramdon content" not related to the topic (I have set the temperature to 0 and top_p 0.9) ... but still does not "creates" summaries of provided text.
So my question/concerns are:
1. Is summarization chain expected to run in parallel mode with chatModel LLMs? If so ... can anyone provide a sample .. can't make it to work in parallel.
2. Is "completion llms" (aka normal llm model) only good for "generating content" but not for "summaries"? Using gpt 3.5 turbo?
Thanks for your help in advace.

### Reproduction
Within this file, I was expecting db_collection to have embeddings when it was printed. However, the output is like this:
> db_collection {'ids': ['1234_5678_1'], 'embeddings': None, 'metadatas': [{'source': 'Test0720.txt'}], 'documents': ['Nuclear power in the United States is provided by 99 commercial reactors with a net capacity of 100,350 megawatts (MW), 65 pressurized water reactors and 34 boiling water reactors.\n\nIn 2016 they produced a total of 805.3 terawatt-hours of electricity, which accounted for 19.7% of the nation's total electric energy generation.\n\nIn 2016, nuclear energy comprised nearly 60 percent of U.S. emission-free generation.']}

i have an agent of type AgentType.OPENAI_MULTI_FUNCTIONS and AzureChatOpenAI LLM. I'm trying to use the FAISS embedding capabilities with a VectorStore,
as shown in this example https://techcommunity.microsoft.com/t5/startups-at-microsoft/build-a-chatbot-to-query-your-documentation-using-langchain-and/ba-p/3833134
combine with the instructions here on how to work with agents and vector store

| ### Feature request
I'm getting this back from my LLM:
Observation: Use Search is not a valid tool, try another one.
Obviously the LLM would like to use the search tool, but didn't request it just right. It seems LangChain has been thoroughly tested with OpenAI, but not so much other models. Which is totally understandable considering there are now thousands of models and variations.
Although I'm digging through the code to find a way to do this myself, it would be awesome if LangChain had a well documented module we could enable to interpret or translate response from the LLM.
Obviously in this case I could use the tool list, and string find, and if any of the tool names are found to go with that tool.
### Motivation
Increased compatibility with open source LLM
### Your contribution
Generic example:
tool_names = # python list
for tool_name in tool_names:
if ai_reply.find(tool_name) >= 0:

Hello every one!
I am following the tutorial of [OpenAI function Agent ](https://python.langchain.com/docs/modules/agents/agent_types/openai_functions_agent).
I downloaded the chinook database in MySQL , I made the connection successfully and got good answers from this database using the [SQLDataBase agent tutorial.](https://python.langchain.com/docs/modules/agents/toolkits/sql_database). However, when I try to do sql query using the OpenAI function agent it fails.
I got the following error:
```InvalidRequestError: 'MySQL DB' does not match '^[a-zA-Z0-9_-]{1,64}$' - 'functions.1.name```
When I change to other kind of agents such as CHAT_ZERO_SHOT_REACT_DESCRIPTION is works good.

### Reproduction
Trying out the new [create_structured_output_chain](https://github.com/hwchase17/langchain/blame/9d7e57f5c01f9ac5c8caa439ff083de98f96fdde/langchain/chains/openai_functions/base.py#L267) introduced in #7270 with the setup like described in the [docs](https://python.langchain.com/docs/modules/chains/popular/openai_functions) I wondered about the bad performance. Then I looked at the function call....
Using a very simple example:
```python
class LanguageCode(BaseModel):
""""A single language code in ISO 639-1 format"""
language_code: str = Field(..., description="Language code (e.g. 'en', 'de', 'fr')")
class LanguageClassification(BaseModel):
"""Classify the languages of a user prompt."""
language_codes: list[LanguageCode] = Field(default_factory=list, description="A list of all languages present in the whole text. Exclude code sections, loanwords and technical terms in the text when deciding on the language codes. You have to output at least one language code, even if you are not certain or the text is very short!")
main_language_code: LanguageCode = Field(..., description="Main Language of the text.")
chat_prompt_language = ChatPromptTemplate.from_messages(
[
SystemMessagePromptTemplate.from_template("You are a world-class linguist and fluent in all major languages. Your job is to determine which languages are present in the user text and which one is the main language."),
HumanMessagePromptTemplate.from_template("{text}"),
]
)
chain = create_structured_output_chain(LanguageClassification, llm, chat_prompt_language, verbose=True)
```
Looking at `chain.llm_kwargs['functions']`:
```python
[{'name': '_OutputFormatter',
'description': 'Output formatter. Should always be used to format your response to the user.',
'parameters': {'title': '_OutputFormatter',
'description': 'Output formatter. Should always be used to format your response to the user.',
'type': 'object',
'properties': {'output': {'$ref': '#/definitions/LanguageClassification'}},
'required': ['output'],
'definitions': {'LanguageCode': {'title': 'LanguageCode',
'description': '"A single language code in ISO 639-1 format',
'type': 'object',
'properties': {'language_code': {'title': 'Language Code',
'description': "Language code (e.g. 'en', 'de', 'fr')",
'type': 'string'}},
'required': ['language_code']},
'LanguageClassification': {'title': 'LanguageClassification',
'description': 'Classify the languages of a user prompt.',
'type': 'object',
'properties': {'language_codes': {'title': 'Language Codes',
'description': 'A list of all languages present in the whole text. Exclude code sections, loanwords and technical terms in the text when deciding on the language codes. You have to output at least one language code, even if you are not certain or the text is very short!',
'type': 'array',
'items': {'$ref': '#/definitions/LanguageCode'}},
'main_language_code': {'title': 'Main Language Code',
'description': 'Main Language of the text.',
'allOf': [{'$ref': '#/definitions/LanguageCode'}]}},
'required': ['main_language_code']}}}}]
```
What? I can barely parse this monstrosity, how should GPT3.5 do this?
It is very well known by now, that the function- and variable names as well as the structure and simplicity/unambiguousness (and even the order of arguments) is very important for the performance of function calls.
This implementation wastes a lot of tokens and is detrimental for performance (especially for users who put their trust in langchain and don't benchmark results); and that for a key feature.
Maybe there are features that some additional complexity but this should never introduce a significant performance/token tax for completely unrelated and important use cases?
### Expected behavior
Just as an example, using the exact same model/code with @jxnl s [OpenAISchema](https://github.com/jxnl/openai_function_call) and nothing else:
```python
llm_kwargs={"functions": [LanguageClassification.openai_schema], "function_call": {'name':"LanguageClassification"}}
chain = LLMChain(llm=llm, prompt=chat_prompt_language, verbose=True, llm_kwargs=llm_kwargs)
```
we get the following schema:
```python
{'name': 'LanguageClassification',
'description': 'Classify the languages of a user prompt.',
'parameters': {'type': 'object',
'properties': {'language_codes': {'description': 'A list of all languages present in the whole text. Exclude code sections, loanwords and technical terms in the text when deciding on the language codes. You have to output at least one language code, even if you are not certain or the text is very short!',
'type': 'array',
'items': {'$ref': '#/definitions/LanguageCode'}},
'main_language_code': {'description': 'Main Language of the text.',
'allOf': [{'$ref': '#/definitions/LanguageCode'}]}},
'required': ['language_codes', 'main_language_code'],
'definitions': {'LanguageCode': {'description': '"A single language code in ISO 639-1 format',
'type': 'object',
'properties': {'language_code': {'description': "Language code (e.g. 'en', 'de', 'fr')",
'type': 'string'}},
'required': ['language_code']}}}}
```
Half the tokens and way easier to read/understand which leads to way better performance and robustness.
This can be parsed in a single line:
```python
res=chain.generate([{'text':"..."}])
LanguageClassification(**json.loads(res.generations[0][0].message.additional_kwargs['function_call']["arguments"])
```
And thus there isn't even more code necessary compared to the native langchain implementation.
I didn't do any extensive benchmarks, but for the usecase above, the Langchain implementation was slower and returned wrong results way more often; which doesn't surprise me, given well-known function_call best practices.
Sorry if I might sound slightly offensive here, but I love to use langchain due to the many integrations and my familarity with it, but problems/implementations like this will really, really hurt adoption in the longterm imho. Hidden complexity can have itsreasons, but hidden complexity that deteriorates results significantly for important use cases without obvious reasons is really the worst.
EDIT
The `create_extraction_chain_pydantic` is better, but still unnecessary bloated (and as often, it´s not clear from the documentation, what the differences are and which one is preferred for which use case... - `create_structured_output_chain` seems to be advertised as "Popular"):

| ### System Info
LangChain Version- 0.0.235, Windows, Python Version-3.9.16
As per below source code of SQLDatabase, before executing any sql query, connection.exec_driver_sql(f"SET search_path TO {self._schema}") is executed for all database except 'snowflake' and 'bigquery'.
if self._schema is not None:
if self.dialect == "snowflake":
connection.exec_driver_sql(
f"ALTER SESSION SET search_path='{self._schema}'"
)
elif self.dialect == "bigquery":
connection.exec_driver_sql(f"SET @@dataset_id='{self._schema}'")
else:
connection.exec_driver_sql(f"SET search_path TO {self._schema}")
cursor = connection.execute(text(command))
As per my knowledge, The SET search_path command is specific to PostgreSQL, not Oracle. This is why I am getting the following error.
sqlalchemy.exc.DatabaseError: (oracledb.exceptions.DatabaseError) ORA-00922: missing or invalid option
[SQL: SET search_path TO evr1]
(Background on this error at: https://sqlalche.me/e/20/4xp6)
Oracle does not recognize this command.
I think it is better to use SCHEMA.TABLE in all sql queries.

Hi I've tried doing the search functionalities using pymilvus and everything works perfectly fine doing similarity search, i am able to get the most relevant documents. However, when i try using the same credentials and parameters on Langchain.vectorstore.Milvus i am unable to replicate the results. Not sure if the connection is correct but my similarity search is returning a blank list. This is the exact same credentials i'm using currently for my on-prem Milvus
`vdb = Milvus(
collection_name = 'bbc_news',
embedding_function = embedding_model,
connection_args = {'host': 'server_host','port':'19530','user':'admin','password':'password','database':'db_dsg'},
consistency_level = "Session",
index_params = index_params,
search_params = search_params
)`
`vdb.similarity_search("What is the price of crude oil")`
Returns a blank list. Am i doing anything wrong here?

Hi,
Here is how i have initilized conversation memory
memory = ConversationSummaryBufferMemory(llm=llm_model,memory_key="chat_history",return_messages=True,max_token_limit=500)
Here is how I have used ConversationalRetrievalChain
chain=ConversationalRetrievalChain.from_llm(llm_model,retriever=vector.as_retriever(search_kwargs={"k": 10}), memory=memory,verbose=True)
I could see that answer for first question will be good, on asking further questions with
result = chain({"question": <question>}) answer from bot is not good for few questions. With verbose enabled I have observed that apart from the actual history langchain is adding few more conversations by itself. Is there a way to supress this(adding additional conversation)
I also tried with ConversationBufferWindowMemory aswell. There also Iam seeing the performance drop. I tried with new langchain version as well "0.0.235", there also Iam seeing the same issue. Could you help me to undersatnd if this is an existing issue or any mistake am I doing while configuring

| ### Feature request
It would be nice if HuggingFaceHub models could be called in async mode (concurrently), as currently supported by Anthropic and OpenAI models.
### Motivation
I wanted to compare performance of some models in a bunch of tasks. I was comparing Anthropic and OpenAI models, and when I tried using a HuggingFaceHub model, I noticed this functionality is not implemented.
### Your contribution
I would like to know if someone is already taking on this. I could try to replicate code from other APIs to do it, but I am not sure I would be able to get to a level that is high enough to submit to LangChain. | Async calls for HuggingFaceHub | https://api.github.com/repos/langchain-ai/langchain/issues/7902/comments | 6 | 2023-07-18T19:59:17Z | 2023-11-15T16:08:10Z | https://github.com/langchain-ai/langchain/issues/7902 | 1,810,625,788 | 7,902 |

| ### Issue you'd like to raise.
Hi,
I'm updating my code to use the new OpenAI function calling structure.
Requirements:
- New messages saved in DynamoDB together with past messages for a user
- Custom prompt : 10 last messages from DynamoDB memory of the user
- Function calling
### Past code
The `create_prompt_from_messages(n)` function create a custom prompt based on n last messages.
```python
chain = LLMChain(llm=llm,
prompt=create_prompt_from_messages(10),
verbose=False,
memory=memory
)
```
### New code without custom prompt
This code below works but send **all** past messages to the LLM. I want to limit to **n** last messages. I didn't find a way to pass custom prompt to an agent using `AgentType.OPENAI_FUNCTIONS`
Note that I don't want to delete past messages from the database.
```python
message_history = DynamoDBChatMessageHistory(table_name=conversation_table_name, session_id='0')
memory = ConversationBufferMemory(memory_key="chat_history", chat_memory=message_history, return_messages=True)
agent_kwargs = {
"extra_prompt_messages": [MessagesPlaceholder(variable_name="chat_history")],
}
agent = initialize_agent(
tools,
llm,
agent=AgentType.OPENAI_FUNCTIONS, # or OPENAI_MULTI_FUNCTIONS ?
verbose=True,
agent_kwargs=agent_kwargs,
memory=memory
)
```
How can I only sent n last message from the agent memory? Or create the a custom prompt and pass it to the OpenAI function agent?
Thank you in advance!

### Reproduction
Hello,
I'm trying to use a Structured Chat agent with SQL tools as well as a VectorStoreQA tool in order to retrieve data from a Postgres database and our Pinecone store. For the Agent's chat model, I'm using Azure OpenAI's gpt-3.5-turbo version 0301.
I have tried providing the tools via the SQLDatabaseToolkit's get_tools() function as well as importing the individual tools and modifying their descriptions, but I get the same issue with both approaches. Despite the descriptions and formatting instructions provided below, the agent has a lot of trouble with querying the DB.
It almost always starts off with 'sql_db_query' to construct a query that errors out, which then prompts the agent to check the list of tables and then their schemas. From here, it can usually arrive at the correct query - but this is not the correct behavior. Other times, it will get stuck in a loop of constructing a query, getting an error, and then either checking the query or just constructing a new one. The errors are due to the schema that it hallucinates because it didn't use the 'sql_db_list_tables' and 'sql_db_schema' tools first.
In the code excerpt below, you can see the formatting instructions provided as well as the descriptions that I'm giving the SQL tools.
Has anybody else had issues with SQL database tools and the StructuredChat agent? Should I be using a different type of agent for this?

1. Create a Chroma store which is locally persisted
```
store = Chroma.from_texts(
texts=docs, embedding=embeddings, metadatas=metadatas, persist_directory=environ["DB_DIR"]
)
```
2. Get the error `You are using a deprecated configuration of Chroma. Please pip install chroma-migrate and run `chroma-migrate` to upgrade your configuration. See https://docs.trychroma.com/migration for more information or join our discord at https://discord.gg/8g5FESbj for help!`

| ### Issue you'd like to raise.
what is the difference between a conversationChain and a conversationalRetrieval chain. I had originially assumed that the conversational retrieval chain would be able to take in documents, input, and memory (which I have gotten to successfully work) and was under the assumption that the conversationChain could not take in our own documents. However, I found a demo online that suggests otherwise. So what exactly is the difference? It was natural to me to use conversationalretrieval chain becuase I had personal documents I wanted to use and I knew that the retrieval chains were made for that.

When using the python_repl tool with the ZeroShotAgent, I keep getting the following error: `Observation: SyntaxError('invalid syntax', ('<string>', 2, 1, '%matplotlib inline\n'))
Thought:`
The agent keeps looping over and over since it does not understand the issue with the magic command.
Is this a known issue? Do we have a fix or ideally a way to enforce some behaviours within the python tool, via a custom prompt?

| ### Feature request
I think it'd be a good idea to have Langchain integrated into the fast healthcare interoperability resource (FHIR) API. Integrating chatting techniques with FHIR and having the ability to interact with ChatOpenAI would give FHIR more visibility, versatility, and adaptability in terms of use cases in healthcare.
### Motivation
Integrating a ChatOpenAI with FHIR (Fast Healthcare Interoperability Resources) can provide several benefits in the healthcare domain:
**Real-time Communication:** Integrating the chat techniques such as ChatOpenAI with FHIR, will have the conversations seamlessly linked to relevant patient health records and clinical data, enhancing the context and relevance of the discussions.
**Collaborative Decision-Making**: By integrating a chat with FHIR, healthcare teams can discuss patient cases, share insights, exchange knowledge, and make informed decisions together. The ability to refer to FHIR resources, such as clinical notes, lab results, or medication information, within the chat streamlines the decision-making process.
**Contextual Information:** FHIR provides a standardized format for representing and exchanging healthcare data. Integrating the chat stream with FHIR allows relevant patient data, such as demographics, diagnoses, allergies, medications, or procedures, to be readily accessible within the chat interface.
**Workflow Efficiency**: By integrating the Lnangchain's ChatOpenAI with FHIR, healthcare professionals can conveniently access patient data and perform necessary actions within the chat interface. For example, they can request lab results, schedule appointments, prescribe medications, or document clinical notes directly within the chat stream. This integration reduces the need for switching between multiple systems, streamlines workflow, and enhances productivity.
**Continuity of Care:** Integrating the chat stream with FHIR helps ensure continuity of care by maintaining a historical record of discussions, decisions, and interventions in the patient's health record. This allows healthcare professionals to refer to previous conversations, review treatment plans, and track the progression of care over time. It also supports care coordination and handoffs between healthcare providers.
**Patient Engagement:** Chat streams integrated with FHIR can empower patients to actively participate in their own healthcare journey. Patients can securely communicate with healthcare providers, ask questions, receive educational materials, or provide updates on their health status. Having access to their FHIR-based health data within the chat stream can enable patients to have informed discussions and take ownership of their care.
The motivation for integrating Langchain with ChatOpenAI is endless.
### Your contribution
I thought of this because I have been studying FHIR for a while now. I am yet to understand the nitty-gritty but I am sure the API has a schema https://fhir-ru.github.io/downloads.html that can be downloaded and integrated. In addition, Langchain developers have built API agents, they can do it.
I am happy to provide more information. | Integrating Langchain to FHIR API | https://api.github.com/repos/langchain-ai/langchain/issues/7881/comments | 11 | 2023-07-18T13:24:11Z | 2024-05-18T23:26:45Z | https://github.com/langchain-ai/langchain/issues/7881 | 1,809,932,575 | 7,881 |

2)without **run**

| ### Feature request
The current Telegram loader is not very flexible. For example:
```
async for message in client.iter_messages(self.chat_entity):
```
Here are the arguments available in the api
```
def iter_messages(
self: 'TelegramClient',
entity: 'hints.EntityLike',
limit: float = None,
*,
offset_date: 'hints.DateLike' = None,
offset_id: int = 0,
max_id: int = 0,
min_id: int = 0,
add_offset: int = 0,
search: str = None,
filter: 'typing.Union[types.TypeMessagesFilter, typing.Type[types.TypeMessagesFilter]]' = None,
from_user: 'hints.EntityLike' = None,
wait_time: float = None,
ids: 'typing.Union[int, typing.Sequence[int]]' = None,
reverse: bool = False,
reply_to: int = None,
scheduled: bool = False
) -> 'typing.Union[_MessagesIter, _IDsIter]':
"""
Iterator over the messages for the given chat.
The default order is from newest to oldest, but this
behaviour can be changed with the `reverse` parameter.
If either `search`, `filter` or `from_user` are provided,
:tl:`messages.Search` will be used instead of :tl:`messages.getHistory`.
.. note::
Telegram's flood wait limit for :tl:`GetHistoryRequest` seems to
be around 30 seconds per 10 requests, therefore a sleep of 1
second is the default for this limit (or above).
Arguments
entity (`entity`):
The entity from whom to retrieve the message history.
It may be `None` to perform a global search, or
to get messages by their ID from no particular chat.
Note that some of the offsets will not work if this
is the case.
Note that if you want to perform a global search,
you **must** set a non-empty `search` string, a `filter`.
or `from_user`.
limit (`int` | `None`, optional):
Number of messages to be retrieved. Due to limitations with
the API retrieving more than 3000 messages will take longer
than half a minute (or even more based on previous calls).
The limit may also be `None`, which would eventually return
the whole history.
offset_date (`datetime`):
Offset date (messages *previous* to this date will be
retrieved). Exclusive.
offset_id (`int`):
Offset message ID (only messages *previous* to the given
ID will be retrieved). Exclusive.
max_id (`int`):
All the messages with a higher (newer) ID or equal to this will
be excluded.
min_id (`int`):
All the messages with a lower (older) ID or equal to this will
be excluded.
add_offset (`int`):
Additional message offset (all of the specified offsets +
this offset = older messages).
search (`str`):
The string to be used as a search query.
filter (:tl:`MessagesFilter` | `type`):
The filter to use when returning messages. For instance,
:tl:`InputMessagesFilterPhotos` would yield only messages
containing photos.
from_user (`entity`):
Only messages from this entity will be returned.
wait_time (`int`):
Wait time (in seconds) between different
:tl:`GetHistoryRequest`. Use this parameter to avoid hitting
the ``FloodWaitError`` as needed. If left to `None`, it will
default to 1 second only if the limit is higher than 3000.
If the ``ids`` parameter is used, this time will default
to 10 seconds only if the amount of IDs is higher than 300.
ids (`int`, `list`):
A single integer ID (or several IDs) for the message that
should be returned. This parameter takes precedence over
the rest (which will be ignored if this is set). This can
for instance be used to get the message with ID 123 from
a channel. Note that if the message doesn't exist, `None`
will appear in its place, so that zipping the list of IDs
with the messages can match one-to-one.
.. note::
At the time of writing, Telegram will **not** return
:tl:`MessageEmpty` for :tl:`InputMessageReplyTo` IDs that
failed (i.e. the message is not replying to any, or is
replying to a deleted message). This means that it is
**not** possible to match messages one-by-one, so be
careful if you use non-integers in this parameter.
reverse (`bool`, optional):
If set to `True`, the messages will be returned in reverse
order (from oldest to newest, instead of the default newest
to oldest). This also means that the meaning of `offset_id`
and `offset_date` parameters is reversed, although they will
still be exclusive. `min_id` becomes equivalent to `offset_id`
instead of being `max_id` as well since messages are returned
in ascending order.
You cannot use this if both `entity` and `ids` are `None`.
reply_to (`int`, optional):
If set to a message ID, the messages that reply to this ID
will be returned. This feature is also known as comments in
posts of broadcast channels, or viewing threads in groups.
This feature can only be used in broadcast channels and their
linked megagroups. Using it in a chat or private conversation
will result in ``telethon.errors.PeerIdInvalidError`` to occur.
When using this parameter, the ``filter`` and ``search``
parameters have no effect, since Telegram's API doesn't
support searching messages in replies.
.. note::
This feature is used to get replies to a message in the
*discussion* group. If the same broadcast channel sends
a message and replies to it itself, that reply will not
be included in the results.
scheduled (`bool`, optional):
If set to `True`, messages which are scheduled will be returned.
All other parameter will be ignored for this, except `entity`.
Yields
Instances of `Message <telethon.tl.custom.message.Message>`.
Example
.. code-block:: python
# From most-recent to oldest
async for message in client.iter_messages(chat):
print(message.id, message.text)
# From oldest to most-recent
async for message in client.iter_messages(chat, reverse=True):

# Getting comments from a post in a channel:

print(message.chat.title, message.text)
"""
```
Of particular interest to me is the ability to specify `offset_date`, `limit`, and `reverse`. Other users may have other needs. I understand that the `BaseLoader` load method signature doesn't allow for any arguments. That leaves two options (perhaps there is a third way?):
1. Provide something like `**telegram_kwargs` in the TelegramApiChatLoader loader constructor, e.g.
```
class TelegramChatApiLoader(BaseLoader):
"""Loader that loads Telegram chat json directory dump."""
def __init__(
self,
chat_entity: Optional[EntityLike] = None,
api_id: Optional[int] = None,
api_hash: Optional[str] = None,
username: Optional[str] = None,
file_path: str = "telegram_data.json",
**telegram_kwargs # <---- add this new argument
):
```
2. Alternatively, refactor the `fetch_data_from_telegram` method and extract `async for message in client.iter_messages(self.chat_entity):` into a separate method that can be overriden by child classes, e.g.:
```
async def fetch_data_from_telegram(self) -> None:
"""Fetch data from Telegram API and save it as a JSON file."""
from telethon.sync import TelegramClient
data = []
async with TelegramClient(self.username, self.api_id, self.api_hash) as client:
# change this line to call a local method
async for message in self.iter_messages(client, self.chat_entity):
is_reply = message.reply_to is not None
reply_to_id = message.reply_to.reply_to_msg_id if is_reply else None
data.append(
{
"sender_id": message.sender_id,
"text": message.text,
"date": message.date.isoformat(),
"message.id": message.id,
"is_reply": is_reply,
"reply_to_id": reply_to_id,
}
)
with open(self.file_path, "w", encoding="utf-8") as f:
json.dump(data, f, ensure_ascii=False, indent=4)
**# Add this new method**
def iter_messages(client: TelegramClient, chat_entity: Optional[EntityLike]):
return client.iter_messages(self.chat_entity, self._offset, self._limit, ...):
```
A child class can then override the constructor and the `iter_message` method.
My current approach is to override the entire `fetch_data_from_telegram` method. This is problematic since I am duplicating code that may change in future versions of langchain
### Motivation
My use case is pretty simple, return all message starting from a certain date. As I understand the current implementation, the entire history is returned.
### Your contribution
I'm happy to submit a PR if one of the abovementioned approaches is approved. | Refactoring telegram loader | https://api.github.com/repos/langchain-ai/langchain/issues/7873/comments | 2 | 2023-07-18T07:55:37Z | 2023-10-24T16:06:13Z | https://github.com/langchain-ai/langchain/issues/7873 | 1,809,372,101 | 7,873 |

| ### Feature request
The WeaviateHybridSearchRetriever does not currently have an option to retrieve scores and explanations. The lack of this feature limits the usability of the retriever, as users cannot gain insights into the scoring logic behind the search results. The feature to retrieve scores and explanations, as provided in the Weaviate library, needs to be integrated into the WeaviateHybridSearchRetriever.
Relevant Weaviate library documentation: [Hybrid search](https://weaviate.io/developers/weaviate/search/hybrid)
### Motivation
Having access to scores and explanations is crucial for users who need to understand how each result has been scored by the hybrid search algorithm. Such understanding can help in refining search queries and filtering results that do not meet certain score thresholds. In the absence of this feature, it becomes difficult to optimize search queries and the quality of the search results can be compromised.
### Your contribution
I am ready to contribute to implementing this feature. I propose to enhance the WeaviateHybridSearchRetriever to include the retrieval of score and explainScore properties from the Weaviate library. This will involve adding relevant parameters and methods in the WeaviateHybridSearchRetriever class. I will also ensure the addition of appropriate tests to validate the functionality and correctness of the implementation. | WeaviateHybridSearchRetriever has no option to retrieve scores and explanations | https://api.github.com/repos/langchain-ai/langchain/issues/7855/comments | 2 | 2023-07-17T20:38:13Z | 2023-07-18T19:50:18Z | https://github.com/langchain-ai/langchain/issues/7855 | 1,808,588,557 | 7,855 |

| ### Issue with current documentation:
I think there is lacking documentation on the multitude of chains regarding QA and retrieval.
There is:
- [retrieval_qa](https://github.com/hwchase17/langchain/tree/master/langchain/chains/retrieval_qa)
- [question_answering](https://github.com/hwchase17/langchain/tree/master/langchain/chains/question_answering)
- [qa_with_sources](https://github.com/hwchase17/langchain/tree/master/langchain/chains/qa_with_sources)
- [conversational_retrieval](https://github.com/hwchase17/langchain/tree/master/langchain/chains/conversational_retrieval)
- [chat_vector_db](https://github.com/hwchase17/langchain/tree/master/langchain/chains/chat_vector_db)
- [question answering](https://github.com/hwchase17/langchain/tree/master/langchain/chains/question_answering)
Which one should be used when? Which are the base chains used by the others etc?
### Idea or request for content:
A structured documentation of the different chains are needed. Maybe some refactoring of the directory structure to group chains. | DOC: What is the difference between the various QA chains? | https://api.github.com/repos/langchain-ai/langchain/issues/7845/comments | 2 | 2023-07-17T16:45:46Z | 2023-11-03T16:06:52Z | https://github.com/langchain-ai/langchain/issues/7845 | 1,808,165,032 | 7,845 |

### Reproduction
1. Extend the class BaseRetriever like the following:
´´´
class DocumentRetrieverExtended(BaseRetriever):
def __init__(self, retriever, vector_field, text_field, k=3, return_source_documents=False, score_threshold=None, **kwargs):
self.k = k
self.vector_field = vector_field
self.text_field = text_field
self.return_source_documents = return_source_documents
self.retriever = retriever
self.filter = filter
self.score_threshold = score_threshold
self.kwargs = kwargs
´´´
2. Provide DocumentRetrieverExtended as retriever object to ConversationalRetrievalChainExtended.from_llm()
3. You will receive the following exception:
```
File "pydantic/main.py", line 357, in pydantic.main.BaseModel.__setattr__
ValueError: "DocumentRetrieverExtended" object has no field "k"
```
### Expected behavior
Until version 0.0.189 it was working properly. Please consider to fix the bug or update the langchain documentation for providing the new way of implementing it (Honestly I was expecting that new releases should not break what was working previously) | BaseRetriever: Latest langchain update is breaking the implementation of extended classes | https://api.github.com/repos/langchain-ai/langchain/issues/7835/comments | 7 | 2023-07-17T14:28:52Z | 2023-11-24T16:07:44Z | https://github.com/langchain-ai/langchain/issues/7835 | 1,807,916,214 | 7,835 |

| ### Feature request
ConversationalRetrievalChain is implementing in the **_call()** method the following behavior:
```
if chat_history_str:
callbacks = _run_manager.get_child()
new_question = self.question_generator.run(
question=question, chat_history=chat_history_str, callbacks=callbacks
)
else:
new_question = question
```
Please add the possibility to avoid this step, like the following:
```
qa = ConversationalRetrievalChainExtended.from_llm(
llm=self.llm,
retriever=self.retriever,
combine_docs_chain_kwargs={"prompt": PROMPT},
return_source_documents=True,
verbose=True,
memory=self.memory,
generate_question=False
)
```
In order to avoid the generation of a new question
### Motivation
The current behavior is not generic and applicable to all the LLMs. Some Foundation Models require a specific format for the template (e.g.) and this is causing exceptions on generating the question (e.g. multiple times Anthropic is generating empty results). Moreover, most of the people is already formatting the template for having the desired behavior. Please include this feature ASAP
### Your contribution
I've already extended the class. Please let me know if you need the code (is a small change you should apply, strange it is not the standard behavior) | ConversationalRetrievalChain: Add parameter for not invoking self.question_generator.run() | https://api.github.com/repos/langchain-ai/langchain/issues/7834/comments | 1 | 2023-07-17T14:23:37Z | 2023-10-23T16:06:22Z | https://github.com/langchain-ai/langchain/issues/7834 | 1,807,906,358 | 7,834 |

### Expected behavior
I expect the vectorstore to not fail, when the fetch_k parameter is higher, than the amount of Documents in the vector db.
Especially since the default value of the fetch_k parameter is set to 20, this can lead to a lot of unwanted errors, when trying to use the vector db for the first time with few documents to test the behaviour. | Weaviate MMR Search fails with too high fetch_k parameter | https://api.github.com/repos/langchain-ai/langchain/issues/7829/comments | 3 | 2023-07-17T12:26:21Z | 2023-10-23T16:06:27Z | https://github.com/langchain-ai/langchain/issues/7829 | 1,807,668,123 | 7,829 |

| ### System Info
I have a use case where I ask an AI agent to check if an article adheres to certain guidelines in documents. However, the recent changes in the BaseConversationalRetrievalChain _call function are causing issues. The process of requesting information from OpenAI can be divided into two steps.
In Step 1, the request, chat history, and system prompt are sent, and the question is rephrased. This step aims to prevent the retrieval of irrelevant documents and ask a more accurate question.
In Step 2, the rephrased question, along with the rephrased chat history and documents, is sent to OpenAI to receive an answer. The problem arises after the upgrade, as the library now sends the rephrased question instead of the original question.
In the process of rephrasing the question, the article is removed from the body of the question. As a result, the AI bot is no longer able to respond effectively.
A possible fix, is sending original question in Step2, it would be nice to be able to decide on it using function parameter.

Document
Doc: Golden guidelines for article
Golden guidelines for articles are as following:
1. Keep the article content as short possible
2. Don’t add new content. It should be a refinement and improvement of what is already there to maintain accuracy
3. Use a clear and concise writing style: Keep sentences short and to the point.
4. Organise content using headings and subheadings: Divide the article into sections with relevant headings, making it easy for readers to find the information they need.
5. Make sure page titles and section headings are action-focused and not in question format
6. Use bullet points and numbered lists to show information in a clear and organised structure
7. Highlight important information using bold or italic text: Emphasise key points or specific instructions by using bold or italic formatting.
------
ask this question:
Review the following document and check if it is following golden guidelines, here is my doc
---------
What is an eTicket?
Instead of a paper ticket, your ticket will be emailed to you as a PDF attachment. If you miss the email, it will also be available for download from the trip itinerary page of your TravelPerk account.
This saves you time at the train station as you no longer have to print a ticket from a ticket machine.
How do I get an eTicket?
When searching for a train in the UK:
Select your preferred time and click on See tickets.
Scroll down to Ticket delivery method.
Select Get an eTicket.
Click on Add to trip.
You will receive the PDF ticket with your TravelPerk confirmation email. You will also be able to download it from your account under Trips -> select a specific trip.
How do I use my eTicket?
It’s really easy! Simply open the PDF ticket on your phone and scan the barcode when you travel.
If there is no scanner at the station, just show the eTicket to a staff member at the barrier.
rephrased question:
Review provided article
final response: As an AI, I can't review the article titled "What is an eTicket?" because you haven't provided the content of the article. Please provide the article content
### Expected behavior
expected answer would be sth like this:
The article is well-structured and follows the Golden guidelines for articles. Here are some points to note:
1. Relevance: The article is very relevant to its intended audience, which seems to be those using eTickets for train travel in the UK.
2. Clarity: The article is clear and easy to understand. The language is simple and the sentences are concise.
3. Depth: The article provides a good level of detail on its subject. It answers many potential questions a reader might have about eTickets and provides step-by-step instructions on how to get and use them.
4. Accuracy: The information in the article appears to be accurate, although without further context or sources, it's hard to verify. | Rephrased question causing issues | https://api.github.com/repos/langchain-ai/langchain/issues/7828/comments | 3 | 2023-07-17T10:37:53Z | 2024-01-30T04:37:03Z | https://github.com/langchain-ai/langchain/issues/7828 | 1,807,476,168 | 7,828 |

### Reproduction
Create a vectorstore with some documents
Try this code to retrieve the documents
`
from chromadb.config import Settings
from langchain.embeddings import OpenAIEmbeddings
from langchain.vectorstores import Chroma
embeddings = OpenAIEmbeddings()
vectorstore = Chroma(
collection_name="langchain_store",
embedding_function=embeddings,
client_settings=Settings(anonymized_telemetry=False),
persist_directory="./dist/vectordb",
)
retriever = vectorstore.as_retriever(search_kwargs={"k": 3})
docs = retriever.get_relevant_documents("quantos litros de oleo vai no motor?")
print(docs)`
The result is [] no documents
Now if I change the client_settings parameter to
client_settings=Settings(anonymized_telemetry=False, chroma_db_impl="duckdb+parquet", persist_directory="./dist/vectordb"),
I get the results correct

### Reproduction
Embed from the confluence loader documents direct to weaviate.from_documents and you will get errors related to the id. (e.g.: {'error': [{'message': "'id' is a reserved property name, no such prop with name 'id' found in class 'LangChain_96f9046045fd4623acec34b0ee6acebb' in the schema. Check your schema files for which properties in this class are available"}]}_
**** Code to reproduce ****
from langchain.document_loaders import ConfluenceLoader
loader = ConfluenceLoader(url="https://yoursite.atlassian.com/wiki", token="12345")
documents = loader.load(
space_key="SPACE", include_attachments=True, limit=50, max_pages=50
)
text_splitter = CharacterTextSplitter(chunk_size=1000, chunk_overlap=0)
docs = text_splitter.split_documents(documents)
embeddings = OpenAIEmbeddings()
db = Weaviate.from_documents(docs, embeddings, weaviate_url=WEAVIATE_URL, by_text=False)
I can fix it by creating a new list with documents that have pageid instead of id in metadata:
new_documents = []
for doc in documents:
metadata = doc.metadata.copy()
metadata['pageid'] = metadata.pop('id')
new_doc = Document(page_content=doc.page_content, metadata=metadata)
new_documents.append(new_doc)
and then continue with :
db = Weaviate.from_documents(docs, embeddings, weaviate_url=WEAVIATE_URL, by_text=False)
### Expected behavior
Documents to get embedded without the error of: {'error': [{'message': "'id' is a reserved property name, no such prop with name 'id' found in class 'LangChain_96f9046045fd4623acec34b0ee6acebb' in the schema.

### Reproduction
This may be related to https://github.com/hwchase17/langchain/issues/7785 , I am not sure. When I use HuggingFaceEndpoint in regular, non-streaming mode, I see that the reply comes truncated.
1. Deploy Falcon-7b https://huggingface.co/tiiuae/falcon-7b
2. Use RetrievalQA and HuggingFaceEndpoint as described in https://github.com/hwchase17/langchain/issues/7785
3. Use the prompt described in https://github.com/hwchase17/langchain/issues/7786 (not sure if you really need this to reproduce)
4. Call it using structured_result = my_qna({query_key: query})
5. The result will come back truncated. No streaming is performed, no token callbacks run, so you will get the json from the reply: structured_result["result"]
In my case, the question and answer in Portuguese:
```
O que é a série G?
A série G da Scania traz uma cabina com uma estética moderna e um confort
```
The last word is truncated, and the whole rest of the explanation is missing.
### Expected behavior
A complete answer, full text.

| ### System Info
Issue:
I'm experiencing an issue while trying to apply the `frequencyPenalty` parameter to the `ChatOpenAI` class in my Flask server setup. I'm running a Flask server that handles a POST query and returns a streaming response from GPT using LlamaIndex.
When I attempt to apply the `frequencyPenalty` parameter to `ChatOpenAI` instance, the server throws a warning:
```python
WARNING! frequencyPenalty is not default parameter.
frequencyPenalty was transferred to model_kwargs.
Please confirm that frequencyPenalty is what you intended.
```
Upon reviewing the documentation, I didn't find a clear way to apply the `frequencyPenalty` to the `ChatOpenAI` class.
Here's a snippet of my current code where I'm experiencing this issue:
```python
# LLM that supports streaming
llm = ChatOpenAI(model_name="gpt-3.5-turbo-16k", streaming=True, frequencyPenalty=6)
llm_predictor = LLMPredictor(llm=llm)
```
I'm using `ChatOpenAI` to create an instance of the LLM that supports streaming. I intended to apply `frequencyPenalty` to this instance but encountered the above warning.
For further reference, the complete code of my Flask server setup is shared in the original post.
Any guidance on how to correctly apply the `frequencyPenalty` to `ChatOpenAI` would be greatly appreciated. Thanks in advance!

### Expected behavior
I expect to be able to apply the frequencyPenalty parameter to the ChatOpenAI class without encountering any warning messages or errors. Ideally, the frequencyPenalty should influence the LLM's generation by tuning the model's likelihood to avoid frequently occurring responses. I'm expecting this to work seamlessly with other parameters and configurations I'm setting up for my ChatOpenAI instance.
If there is a specific way or an alternate parameter to achieve this functionality, I would expect the documentation to clearly illustrate this. Also, any warnings or error messages should provide actionable insights or steps for resolution. | Unable to Apply frequencyPenalty Parameter to ChatOpenAI Class | https://api.github.com/repos/langchain-ai/langchain/issues/7788/comments | 2 | 2023-07-16T12:52:03Z | 2023-10-30T16:05:43Z | https://github.com/langchain-ai/langchain/issues/7788 | 1,806,570,994 | 7,788 |

| ### Feature request
In AmazonKendraRetriever, user should have access to a page_content formatter in order to format a Kendra ResultItem as desired, e.g. by combining all sorts of possible document attributes with the title and excerpt of the item.
Currently, the [AmazonKendraRetriever](https://github.com/hwchase17/langchain/blob/master/langchain/retrievers/kendra.py#L30) does not expose a template or allow the user to overwrite how the value of the Document page_content is generated.
Let me know what you think. I am open to suggestions.
@3coins @baskaryan
### Motivation
The Amazon Kendra result item provides not only the title and excerpt but all sorts of customizable document attributes that could be combined to improve the result of the LLM completion.
For instance, according to the official [Amazon Kendra documentation](https://docs.aws.amazon.com/kendra/latest/APIReference/API_RetrieveResultItem.html):
> DocumentAttributes
> An array of document fields/attributes assigned to a document in the search results. For example, the document author (_author) or the source URI (_source_uri) of the document.
>
> Type: Array of [DocumentAttribute](https://docs.aws.amazon.com/kendra/latest/APIReference/API_DocumentAttribute.html) objects
>
> Required: No
Different use cases could leverage on the ability to change the Document page_content final value as close to the Kendra Retriever as possible.
### Your contribution
I would be glad to work on this feature.

### Reproduction
I provisioned [cerebras/Cerebras-GPT-2.7B](https://huggingface.co/cerebras/Cerebras-GPT-2.7B) and noticed I was getting an empty string when asking a question with my prompt, in "text-generation" mode. Upon debugging I found the issue:
```
if self.task == "text-generation":
# Text generation return includes the starter text.
text = generated_text[0]["generated_text"][len(prompt) :]. # <==== HERE
elif self.task == "text2text-generation":
text = generated_text[0]["generated_text"]
elif self.task == "summarization":
text = generated_text[0]["summary_text"]
```
I had to patch it like this:
```
text = generated_text[0]["generated_text"]
```
That is so because generated_text[0]["generated_text"] is NOT returning with the prompt text. Therefore, [len(prompt) :] effectively discards the actual answer. Basically, from debugging I see that the logic I want is the same as is coded under "text2text-generation". But I am using "text-generation" and the answer *does not* come with the prompt text back. Any chance the logic for these 2 are swapped?

### Reproduction
I use RetrievalQA.from_chain_type(llm=llm, ...) and with these LLMs streaming works:
- ChatOpenAI. (I can pass streaming=True)
- OpenAI. (I can pass streaming=True)
However, with HuggingFaceEndpoint the streaming just does not work. It does not even take streaming=bool.
### Expected behavior
I am able to switch LLM engines via config, and would like to have the streaming feature as the output is incrementally shown to the user, which is great for slow responses (much better usability - no need to wait for the entire time to compute the entire answer). Unfortunately this is not possible with HuggingFaceEndpoint.
https://github.com/hwchase17/langchain/issues/2918 talks about HuggingFaceHub , which is not really my case (HuggingFaceEndpoint)
Is there a simple way to make it work with RetrievalQA.from_chain_type(llm=llm,...) where the llm is created like
```
llm = HuggingFaceEndpoint(endpoint_url=my_endpoint,
task="text-generation",
streaming=True
callbacks = callbacks,
model_kwargs={"temperature": temperature, "max_length": 1024})

2. Follow instructions here: https://python.langchain.com/docs/modules/data_connection/retrievers/integrations/amazon_kendra_retriever
3. Ask for a specific quesiton that will fall back to using the Query API that returns a ResultItem with type ANSWER and inspect the content as following
I replaced the original values with "----------------".
```json
{
"Id": "----------------",

will result in:

### Expected behavior
The document page_content should contain at least the Amazon Kendra ResultItem excerpt.

### Who can help?
Is there a way to get the whole output with Output Parser or OpenAI function calling?
I have a simple prompt where I get the LLM to output responses to a set of questions, and I would like to get a structured response that separates the question number and the response to the question generated by the LLM.
I have been testing it out with Structured Output Parsers but when I use it, the answers I get are often a shortened version of the original answer. This depends on the description I put in the answer_schema below. I've tried a variety of descriptions to capture as much of the original response as possible, but it is always lacking a lot of detail.
```
question_number_schema = ResponseSchema(name = "question_number",
description = "Question Number, e.g. 1, 2, 3", type = "number")
answer_schema = ResponseSchema(name = "answer",
description = "Detailed Response")
response_schemas = [question_number_schema, answer_schema]

This approach allows the language model to learn patterns and vocabularies within the data without the need for explicit human labeling.

These labeled samples consist of input prompts paired with corresponding desired outputs, providing explicit guidance on the desired structure or behavior. This approach is used when specific outputs or classifications are required, such as text classification.
'''
```
I'm currently getting something like:
```
{"Question 3": "Unsupervised fine-tuning updates pre-existing language models using unstructured datasets.",
"Question 4": "Supervised fine-tuning trains language models with labeled samples."}

| ### Issue you'd like to raise.
According to [here](https://python.langchain.com/docs/modules/chains/how_to/call_methods), all subclass inherited from the Chain class will have the `__call__()` and the `run()` methods to launch the chain. And according to the [LLMChain API](https://api.python.langchain.com/en/latest/chains/langchain.chains.llm.LLMChain.html?highlight=llmchain#langchain.chains.llm.LLMChain) and [SimpleSequentialChain API](https://api.python.langchain.com/en/latest/chains/langchain.chains.sequential.SimpleSequentialChain.html#langchain.chains.sequential.SimpleSequentialChain), both of them are inherited from the Chain class. However I found LLMChain and SimpleSequentialChain accept different kinds of input patterns when calling `__call__()` and the `run()`, which are highly confusing.
To demonstrate, consider the following setup, where we create an LLMChain that runs a prompt template that simply asks the LLM to repeat what is told, and attach the LLMChain to a SimpleSequentialChain:
```
from langchain.chains import LLMChain, SimpleSequentialChain
from langchain.prompts import StringPromptTemplate
from pydantic import BaseModel, validator
class CustomTemplate(StringPromptTemplate, BaseModel):
"""A custom prompt template that takes in the path to a json file as input, and formats the prompt template."""
@validator("input_variables")
def validate_input_variables(cls, v):
"""Validate that the input variables are correct."""
if len(v) == 0 or "CustomKwarg" not in v:
raise ValueError("CustomKwarg keyword argument must be provided .")
return v
def format(self, **kwargs) -> str:
return "Repeat the following: \"" + kwargs["CustomKwarg"] + "\""
llmchain = LLMChain(llm=llm,
prompt=CustomTemplate(input_variables=["CustomKwarg"]),
verbose=True)
simplesequentialchain = SimpleSequentialChain(chains=[llmchain])
```
where ``llm`` is a custom llm.
In the prompt template, we expect a keyword argument (kwarg) called `CustomKwarg` to be provided when we launch the chains. There are, however, several ways to provide `CustomKwarg`, e.g. directly providing the value for `CustomKwarg`, or providing a dictionary that maps a key "CustomKwarg" to the value of `CustomKwarg`. Also, sometimes we need to specify `input` or `inputs` as the keyword argument when we make the function call. These lead to many possible combination of syntaxes to launch the chains, and I found that the syntaxes accepted by the LLMChain and SimpleSequentialChain very different and inconsistent. Assuming we want to provide "XYZ!" as the value for CustomKwarg to the chain, see the summary of the launching results below.
|#|command | `c = llmchain` | `c = simplesequentialchain` |
|-|--------------------------------------------- | -----------| --------------------------|
|1|`c("XYZ!")`| O | O|
|2|`c({"CustomKwarg": "XYZ!"})`| O | `Missing some input keys: {'input'}` |
|3|`c({"input": "XYZ!"})`| `Missing some input keys: {'CustomKwarg'}` | O |
|4| `c({"inputs": "XYZ!"})`| `Missing some input keys: {'CustomKwarg'}`| `Missing some input keys: {'input'}` |
|5|`c(input={"CustomKwarg": "XYZ!"})`| `Chain.__call__() got an unexpected keyword argument 'input'` | `Chain.__call__() got an unexpected keyword argument 'input'` |
|6|`c(inputs={"CustomKwarg": "XYZ!"})`| O | `Missing some input keys: {'input'}` |
|7|`c.run("Hello there!")`| O | O |
|8|`c.run({"CustomKwarg": "XYZ!"})`| O | `Missing some input keys: {'input'}` |
|9|`c.run({"input": "XYZ!"})`| `Missing some input keys: {'CustomKwarg'}` | O |
|10|`c.run({"inputs": "Hello there!"})`| `Missing some input keys: {'CustomKwarg'}` | `Missing some input keys: {'input'}`|
|11|`c.run(input={"CustomKwarg": "XYZ!"})`| `Missing some input keys: {'CustomKwarg'}` | O |
|12|`c.run(inputs={"CustomKwarg": "XYZ!"})`| `Missing some input keys: {'CustomKwarg'}` | `Missing some input keys: {'input'}`|
The allowed syntax patterns are highly inconsistent among the two types of chains. For the same syntax, the two types of chains can even fail on different error messages, which is very confusing. Since both of the chains are subclasses of Chain, one would expect them to behave similarly, especially for those methods inherited from the Chain class (`__call__()` and `run()`).
Note: I am using **LangChain ver. 0.0.225**.

langchain version - v0.0.233
chain types used - RetrievalQA, load_qa_chain
I have a huggingface model deployed behind a sagemaker endpoint which produces outputs as expected when run prediction against it directly. However, when I initialize it with SagemakerEndpoint class from langchain, it only return two characters and sometimes an empty string. I scoured through the internet and langchain docs for the last couple days and my initialization and chain prompting aspects of the code seem to be in line with the docs guidelines and anecdotal recommendations laid out.
I think this either a lack integration support for huggingface models deployed with sagemaker or I'm missing something here that's not been written in the docs and examples. Please review and let me know either way.
### Below code will reproduce the behavior I'm experiencing.
```

```
#### Here's the output (or lack thereof) from prompting with langchain, in above code.
```
system_prompt = """<|SYSTEM|># Your are a helpful and harmless assistant for providing clear and succinct answers to questions."""
question = "What is your purpose?"
query = (system_prompt + "<|USER|>" + question + "<|ASSISTANT|>")
llm_response = qa_chain(query)
print(llm_response['result'])
---------------------------------------------------------------------------
Output:
Use the following pieces of context to answer the question at the end. If you don't know the answer, just say that you don't know, don't try to make up an answer.
<some doc context from vectordb goes here - removed due to info sensitivity>
Question: # <|SYSTEM|># Your are a helpful and harmless assistant for providing clear and succint answers to questions.
What is your purpose?
Helpful Answer:
```
As shown above, there's no output for 'Helpful Answer: '.
#### However when I prompt the model directly with a predictor like below, it returns the full output as expected.
### Model returns the full output with the below code which runs direct prediction against the endpoint.
```
import boto3
from sagemaker.huggingface import HuggingFacePredictor
from sagemaker.session import Session
sm_session = Session(boto_session=boto3.session.Session())
payload = {
"inputs": "What is your purpose?",
"parameters": {"max_new_tokens": 256, "do_sample": True}
}
local_llm = HuggingFacePredictor(endpoint, sm_session)
chat = local_llm.predict(data=payload)
result = chat[0]["generated_text"]
print(result)
```
#### Output for direct prediction from the code executed above.
```
What is your purpose?
You seem important. What is your value? What can you do that makes you unique? What is your unique value?
* You are important to the people who know you best.
* When you accomplish the things you want to do, you will become valuable to the people who matter to you.
* We value you because you are special
```
As it can be seen above, the model returns an output (not a great one) but the fact is it does when I'm prompted and not when wrapped with SagemakerEndpoint class and prompted with prompted with langchain.

I've set "langchain.debug=True"; however, it does not work for the DirectoryLoader. I have a notebook that tried to load a dozen or more PDFs, and typically, at least one of the files fails (see attached). I looked at the code, and as far as I can tell, there is no trace or debug feature in (https://github.com/hwchase17/langchain/tree/master/langchain/document_loaders).
My issue is that the loader code is a black box. I can't tell which file is failing; therefore, I have to process each one individually to find out which one is failing. It would be beneficial if a trace/debugger could help me identify which file it's failing on.

| ### Issue with current documentation:
The [Handling Tool Errors section](https://python.langchain.com/docs/modules/agents/tools/how_to/custom_tools#handling-tool-errors) on Defining Custom Tools page has following line as part of the first code cell:
```py
from langchain.schema import ToolException
```
When running this, I get this error:
```py
ImportError: cannot import name 'ToolException' from 'langchain.schema' (<path>\venv\lib\site-packages\langchain\schema\__init__.py)
```
### Idea or request for content:
A quick search for `ToolException` shows that it's defined in `langchain\tools\base.py`, perhaps the docs need to be updated to
```py
from langchain.tools.base import ToolException
``` | DOC: `ToolException` cannot be imported as mentioned on "Defining Custom Tools" page - Python | https://api.github.com/repos/langchain-ai/langchain/issues/7720/comments | 1 | 2023-07-14T17:07:16Z | 2023-07-18T17:08:04Z | https://github.com/langchain-ai/langchain/issues/7720 | 1,805,198,960 | 7,720 |

| ### System Info
Using Lanchain version .233 currently, and each time I make an update and run tests on my project, pip-audit is returning an additional vulnerability. I use Gitlab for the project and I am adding commands to ignore these vulnerabilities in gitlab-ci.yml, but currently the command looks like:
`- pip-audit --ignore-vuln PYSEC-2023-109 --ignore-vuln PYSEC-2023-110 --ignore-vuln PYSEC-2023-98 --ignore-vuln PYSEC-2023-91 --ignore-vuln PYSEC-2023-92`
these are all langchain vulnerabilities.

| ### Feature request
we have the `@tool` decorator and the `Tool.from_function` function.
But they are (or seem to me) inconsistent. The kwargs `handle_tool_error` and `return_direct` are only available in `Tool.from_function` .
Shouldn't be available in both?
Shouldn't be `@tool` just a mirror of `Tool.from_function` ?
### Motivation
I want to be able to do `@tool(handle_tool_error=True)`

**3 - And When I ask questions related to the document that I provided, I get the correct answers from the document and also the outer world answers**
**4 - Also If I ask questions that are not related to this document, still I am getting answers from the outer world(I am expecting an answer such as - "I don't know, the question is beyond my knowledge" from the chain**
**5 - Sometimes I am getting the internal states (Agent response, human response, training data context, internal output, langchain prompt, answer containing page number with full context, partial intermediate answers......)- which I don't want to look, along with the output -**
**6 - Finally each time I am getting different results for the same question.**
Tried verbose= False. But still getting some unwanted details(along with the exact answer) which makes the bot noisy.
How to prevent it?
### Expected behavior
When I ask questions related to the document that I provided, it must return the most relevant answer without any other info like internal states, prompts...etc.
Also if I ask questions that are not related to the document that I provided it shuld return "I don't know, the question is beyond my knowledge" | Getting unwanted/irrelevant/out of context results in document question answering | https://api.github.com/repos/langchain-ai/langchain/issues/7702/comments | 8 | 2023-07-14T12:38:13Z | 2023-12-19T16:23:01Z | https://github.com/langchain-ai/langchain/issues/7702 | 1,804,812,396 | 7,702 |

)
pd_agent.run(prompt)
def test_spark_agent(file, prompt):
spark = SparkSession.builder.getOrCreate()
df = spark.read.csv(file, header=True, inferSchema=True)
spark_agent = create_spark_dataframe_agent(
llm=OpenAI(temperature=0),

)
spark_agent.run(prompt)
if __name__ == "__main__":
file = 'test.csv'

### Expected behavior
**Expected:** No code is execued.
**Suggestion:** Add a sanitizer to check the sensitive prompt and code before passing it into `PythonAstREPLTool`.
**Root Cause:** This vuln is caused by `PythonAstREPLTool._run`, it can run arbitrary code without any checking.
**Real World Impact:** The prompt is always exposed to users, so malicious prompt may lead to remote code execution when these agents are running in a remote server. | Prompt injection which leads to arbitrary code execution | https://api.github.com/repos/langchain-ai/langchain/issues/7700/comments | 5 | 2023-07-14T10:11:00Z | 2023-10-27T19:17:54Z | https://github.com/langchain-ai/langchain/issues/7700 | 1,804,604,289 | 7,700 |

# Combined
memory = CombinedMemory(memories=[vector_memory, summary_memory])
_DEFAULT_TEMPLATE = """The following is a friendly conversation between a human and an AI. The AI is talkative and provides lots of specific details from its context. If the AI does not know the answer to a question, it truthfully says it does not know.

dict_items([('input', 'How are you?'), ('chat_history_lines', 'Human: wow\nAI: Wow!'), ('history', 'Human: wow\nAI: Wow!\nHuman:yes\nAI: Yes!\nHuman: hello\nAI: Hi!')])
```
When adding documents to the vectorstore retriever memory, all items are added except for `self.memory_key` (history). Thus, `chat_history_lines` is included in the created documents, without a way to prevent that.
### Suggestion:
One approach for supporting this would be to add a property to VectorStoreRetrieverMemory that allows the caller to specify which input keys should be included in the created documents. Another approach may be to only create documents with input_key from inputs. | Issue: Cannot use CombinedMemory with VectorStoreRetrieverMemory and ConversationTokenBufferMemory | https://api.github.com/repos/langchain-ai/langchain/issues/7695/comments | 10 | 2023-07-14T06:05:24Z | 2023-08-03T15:00:56Z | https://github.com/langchain-ai/langchain/issues/7695 | 1,804,243,856 | 7,695 |

| ### Issue you'd like to raise.
Hi!
I have some problem with the `NotebookLoader` loader:
I'm trying to access my repo and detect all of the `.ipynb` files, and then load them to the LLM Chain I'm implementing using LangChain. The repo can be viewed [here](https://github.com/eilone/RepoReader/tree/eilon-br)
```
for ext in extensions:
glob_pattern = f'**/*.{ext}'
try:
loader = None
if ext == 'ipynb':
loader = **NotebookLoader**(str(repo_path), include_outputs=True, max_output_length=20,
remove_newline=True, loader_kwargs={"content_type": "text/plain"})
```
Yet I don't know how to pass the `glob_pattern` to this loader, resulting in going to the base dir and not being able to look for the notebook files...
```
[Errno 21] Is a directory: 'my_dir'
```
Can you please help me figure it out? Considering I don't want to pass each `ipynb` file-path individually?

| ### Feature request
Hello, and thanks for this fantastic library!!
In pyproject.toml, the Pydantic library [is pinned to version 1.x](https://github.com/hwchase17/langchain/blob/master/pyproject.toml#L15)
I'd like to unpin that dependency by changing `^1` to `>=1`.
### Motivation
Pydantic 2.0.2 is apparently production-ready, and it has a feature we badly need but our dependency on langchain prevents us from using it.
Deep background on dependency pinning here: https://iscinumpy.dev/post/bound-version-constraints/
### Your contribution
Two tiny commits like [this](https://github.com/rec/langchain/commits/master) and [this one in langsmith](https://github.com/rec/langchainplus-sdk/commits/main) are all that is needed.
I can test the langchain commit and submit it for review; I can send the langsmith one for review, but not sure how to test it. | Uncap pydantic dependency (allow pydantic 2.x) | https://api.github.com/repos/langchain-ai/langchain/issues/7663/comments | 11 | 2023-07-13T14:59:49Z | 2024-02-08T17:41:20Z | https://github.com/langchain-ai/langchain/issues/7663 | 1,803,218,927 | 7,663 |
