| ### Feature request
Name Entity Recognition is the process of identifying and classifying named entities (like people, organizations, dates, and locations) in text.
### Motivation
NER is useful in various areas:
1. Information Retrieval: Helps in improving the efficiency of search engines. For example, if someone searches for "Apple," understanding whether they mean the fruit or the tech company can be crucial.
2. Content Recommendation: For news or media agencies, knowing what entities are mentioned in articles can help in recommending related content to users.
3. Data Mining: For extracting structured information from unstructured datasets.
4. Question Answering: Helps chatbots and virtual assistants understand and respond to user queries more accurately.
5. Knowledge Graph Construction: Crucial for building structured databases of information extracted from text.

| I have made a Custom Prompt template using:
```
`class CustomPromptTemplate(BaseChatPromptTemplate):
# The template to use

# The list of tools available
tools: List[Tool]
def format_messages(self, **kwargs) -> str:
# Get the intermediate steps (AgentAction, Observation tuples)
# Format them in a particular way
intermediate_steps = kwargs.pop("intermediate_steps")
thoughts = ""
for action, observation in intermediate_steps:
thoughts += action.log
thoughts += f"\nObservation: {observation}\nThought: "
# Set the agent_scratchpad variable to that value
kwargs["agent_scratchpad"] = thoughts
# Create a tools variable from the list of tools provided
kwargs["tools"] = "\n".join([f"{tool.name}: {tool.description}" for tool in self.tools])
# Create a list of tool names for the tools provided
kwargs["tool_names"] = ", ".join([tool.name for tool in self.tools])
kwargs["df_head"]=df.head()
formatted = self.template.format(**kwargs)

```
Calling this:
```
prompt = CustomPromptTemplate(
template=template,
tools=tools,
input_variables=["input","intermediate_steps","df_head","history"]
)
```
I have also created custom agent:
```
llm_chain = LLMChain(llm=llm, prompt=prompt)
tool_names = [tool.name for tool in tools]
agent = LLMSingleActionAgent(
llm_chain=llm_chain,
output_parser=output_parser,

)
```
Executing agent:
```

memory=ConversationBufferWindowMemory(memory_key='chat_history', return_messages=True, output_key='answer',k=2)
agent_executor_new = AgentExecutor.from_agent_and_tools(agent=agent, tools=tools, verbose=True,memory=memory)
```
Running this with (**As per documentation**):
```

```
Results in this error:

| ### Issue you'd like to raise.
I am using the STRUCTURED_CHAT_ZERO_SHOT_REACT_DESCRIPTION agent and I am trying to implement tools that take varying number of arguments (e.g. tool1 takes a single argument and tool2 takes 3 arguments). I am using arg_schema to define the arguments and their types. I am wondering how can I return a message to the agent in case the input arguments do not satisfy the arg_schema without erroring out the service. My objective with this is that the agent will try again after modifying the "Thought". How do I do that?

### Expected behavior
The milvus adapter must allow for http uris.
The exception happens because the adapter assumes the uri always starts with `https://`.
Instead one should parse url and get the netloc:
```python
from urllib import parse
given_address = parse.urlparse(uri).netloc

llm=chat_model,
retriever=retriever,
memory=memory,
chain_type="stuff",
combine_docs_chain_kwargs={"prompt": prompt},
get_chat_history=lambda h: h,
condense_question_llm=ChatOpenAI(temperature=0.04),
verbose=True,
)
```
In retriever, `similarity_score_threshold` is not working as expected. For now, I am using `0.8` as `score_threshold` for retriever. I am not getting any Documents in return.
However, this piece of code is giving me the expected Documents. Note that I am not specifying any score during similarity search. I am checking the score of each Document manually with 0.8 as a threshold.
```py
vectorstore.similarity_search_with_score(
query=query,
k=5,
filter={"source": {"$in": self.config.get("author")}},
namespace="my_namespace",
)
```
### Expected behavior
The below piece of codes should return the same Documents from Pinecone.
```py
retriever = vectorstore.as_retriever(
search_type="similarity_score_threshold",
search_kwargs={
"score_threshold": 0.8,
"k": 5,
"filter": {"source": {"$in": self.config.get("author")}},
}
)
```
```py
vectorstore.similarity_search_with_score(
query=query,
k=5,
filter={"source": {"$in": self.config.get("author")}},
namespace="my_namespace",
)

| ### Issue you'd like to raise.
I am using the ConversationBufferWindowMemory class and I would like to have different memories for different users. So that each user has its individual memory.
memory = ConversationBufferWindowMemory(k=3, memory_key="chat_history", return_messages=True)
qa = ConversationalRetrievalChain.from_llm(llm_model, vector_store.as_retriever(search_kwargs={'k': 2}), memory=memory,

### Reproduction
Reference: https://docs.cerebrium.ai/cerebrium/cortex/examples/langchain
As a result it always returns
```Could not import cerebrium python package. Please install it with `pip install cerebrium`.```
as part of the following code
```
from cerebrium import model_api_request
except ImportError:
raise ValueError(
"Could not import cerebrium python package. "
"Please install it with `pip install cerebrium`."
)
```
### Expected behavior
Returns value from the Cerebrium AI instance. | CerebriumAI model_api_request deprecation | https://api.github.com/repos/langchain-ai/langchain/issues/12705/comments | 2 | 2023-11-01T10:57:49Z | 2024-02-01T18:49:21Z | https://github.com/langchain-ai/langchain/issues/12705 | 1,972,145,406 | 12,705 |

As you can see in the code below the UnstructuredFileLoader does not work and can not load the file.
```
from langchain.document_loaders import UnstructuredFileLoader

# UnstructuredFileLoader does not work so I am using UnstructuredFileIOLoader
loader = UnstructuredFileLoader('data/scenario/xodr/common_junction_creator.xodr',mode="single", strategy="fast")
documents_xml = loader.load() #
print(documents_xml)
print(f"Number of documents={len(documents_xml)}")
with open("data/scenario/xodr/road_with_custom_roadmarkers.xodr", "rb") as f:
loader = UnstructuredFileIOLoader(

| ### Issue with current documentation:
While reviewing the document, I am learning about the callback functionality of langchain and have a question.
In langchain.callbacks, there are two classes: `BaseCallbackHandler` and `BaseTracer`.
From what I can see in the document, it seems like the roles of these two classes are similar.
Could you please provide an explanation of the differences between these two classes and clarify when it is appropriate to inherit from each class when creating a custom callback?

| ### Issue you'd like to raise.
With the Pinecone index setup with `cosine` metric, so the scores received from the vector database are already in the`cosine` metric.
However, the `_select_relevance_score_fn` of langchain pinecone vector store returns the base vector store's `_cosine_relevance_score_fn` for the `cosine` distance strategy.
https://github.com/langchain-ai/langchain/blob/b2138508cbf17aef3a08cdce072d79fd5dc63dc3/libs/langchain/langchain/vectorstores/pinecone.py#L231
In the base vector store implementation of `_cosine_relevance_score_fn` the score is the complement.
https://github.com/langchain-ai/langchain/blob/master/libs/langchain/langchain/schema/vectorstore.py#L187
So the cosine metric of 0.81 returned by the pinecone vector database indicating a higher similarity is turned into 0.19 in langchain and processed as very low similarity.

### Reproduction
it is easy to reproduction
use AsyncIteratorCallbackHandler() to get ChatTongyi stream data,
it only get warning:
`/venv/lib/python3.10/site-packages/langchain/chat_models/tongyi.py:365: RuntimeWarning: coroutine 'AsyncCallbackManagerForLLMRun.on_llm_new_token' was never awaited
run_manager.on_llm_new_token(chunk.content, chunk=chunk)`
and the reply text dispeared
I look into the code , and find the problem is in the _agenerate() with only using _generate()
we can see, the stream functionality in _generate() is incomplete and problematic. One of them is the questionable support for asynchronous callback,
and this is where error happens
it should use _astream()
pls, fix it , thx

return stream data | ChatTongyi class use _generate method as async call and result in replying text dispeared | https://api.github.com/repos/langchain-ai/langchain/issues/12695/comments | 8 | 2023-11-01T05:20:30Z | 2024-02-19T16:08:10Z | https://github.com/langchain-ai/langchain/issues/12695 | 1,971,721,957 | 12,695 |

| ### Issue with current documentation:
I have searched for a while but there is no example for RetrievalQA batch inference. For example, here is my code:
`model_name = "sentence-transformers/paraphrase-multilingual-mpnet-base-v2"
embeddings = HuggingFaceEmbeddings(model_name=model_name)
db = ElasticVectorSearch(
embedding = embeddings,
elasticsearch_url="http://localhost:9200",
index_name="test_index",
)
model = transformers.AutoModelForCausalLM.from_pretrained('vilm/vietcuna-7b-v3')
generate_text = transformers.pipeline(
model=model,
tokenizer=tokenizer,
batch_size = 8,
return_full_text=True,
task='text-generation',
stopping_criteria=stopping_criteria,
temperature=0,
max_new_tokens=512,
repetition_penalty=1.1
)
model_id = 'vilm/vietcuna-7b-v3'
llm = HuggingFacePipeline(pipeline=generate_text)
qa = RetrievalQA.from_chain_type(
llm=llm,
chain_type="stuff",
retriever=db.as_retriever(),
verbose=True,
return_source_documents=True,
)
`
then I tried:
`qa.batch(inputs=[{'query':'Who is the prime minister of Vietnam'},{'query':'what is desease?'}])`
and
`qa(inputs=[{'query':'Who is the prime minister of Vietnam'},{'query':'what is desease?'}])`
Both failed. I saw the reason is ElasticVectorSearch cannot return two source documents at the same time. But the main problem is that is there any way to get RetrievalQA do batch inferencing with GPU utilization. LLM batch inference is easy to use (defined params) but it seems like the RetrievalQA chain hasn't supported this.

### Expected behavior
The text should have been parsed. Based on the stack trace:

I'm thinking this is probably derived from the boto3 API response, because it works fine with OpenAI. | Missing 'Action:' after 'Thought: | https://api.github.com/repos/langchain-ai/langchain/issues/12689/comments | 3 | 2023-11-01T01:41:04Z | 2024-02-13T16:08:53Z | https://github.com/langchain-ai/langchain/issues/12689 | 1,971,542,844 | 12,689 |

| ### Issue with current documentation:
I´m using https://python.langchain.com/docs/guides/debugging and https://python.langchain.com/docs/modules/chains/document/refine.
Somehow the documentation does not line up. How can I set verbose=True on a chain when using LCEL?
### Idea or request for content:
Add documentation on how to activate verbose logs on a chain when using LCEL. | DOC: When using LCEL, how do I set verbose=True on a chain? | https://api.github.com/repos/langchain-ai/langchain/issues/12659/comments | 3 | 2023-10-31T17:11:43Z | 2023-10-31T19:56:08Z | https://github.com/langchain-ai/langchain/issues/12659 | 1,970,920,738 | 12,659 |

| ### Feature request
The idea is to have an object that can be used in the same way as `LanguageModel` objects, but the object would contain a list of `LanguageModels` that could be chosen according to rules.
For instance I would to call my list of LLM with a round robin strategy in order to distribute requests among multiple LLM.
Example:
```
llm1 = OpenAI(key1)
llm2 = OpenAI(key2)
muti_llm = MultiLLM([llm1, llm2], method="round-robin")
multi_llm.predict(...) # will use llm1
multi_llm.predict(...) # the second time will use the llm2
```
### Motivation
The motivations behind these features are:
- leveraging multi account to avoid API limits per account
- act as a load balancer to easily create balancing strategies (round robin, random, least connection, ...)
- (in the future maybe) have the possibility to make shadowing between multiple LLM or other strategies
### Your contribution
I started working on that but I'm not sure about the object hierarchy I need to implement to achieve this goal properly without impacting too much the existing codebase.
Here is my naive implementation:
```python
LanguageModelInput = TypeVar("LanguageModelOutput")
class BaseMultiLanguageModel(BaseLanguageModel[LanguageModelInput], ABC):
language_models: List[BaseLanguageModel] = Field(
description="List of language models",
min_items=1
)

...
def generate_prompt(self, prompts: List[PromptValue], stop: Optional[List[str]] = None, callbacks: Callbacks = None, **kwargs: Any) -> LLMResult:
return self.active_model.generate_prompt(prompts, stop, callbacks, **kwargs)
async def agenerate_prompt(self, prompts: List[PromptValue], stop: Optional[List[str]] = None, callbacks: Callbacks = None, **kwargs: Any) -> LLMResult:
return await self.active_model.agenerate_prompt(prompts, stop, callbacks, **kwargs)
def predict(self, text: str, *, stop: Optional[Sequence[str]] = None, **kwargs: Any) -> str:
return self.active_model.predict(text, stop=stop, **kwargs)
def predict_messages(self, messages: List[BaseMessage], *, stop: Optional[Sequence[str]] = None, **kwargs: Any) -> BaseMessage:
return self.active_model.predict_messages(messages, stop=stop, **kwargs)
async def apredict(self, text: str, *, stop: Optional[Sequence[str]] = None, **kwargs: Any) -> str:
return await self.active_model.apredict(text, stop=stop, **kwargs)
async def apredict_messages(self, messages: List[BaseMessage], *, stop: Optional[Sequence[str]] = None, **kwargs: Any) -> BaseMessage:
return await self.active_model.apredict_messages(messages, stop=stop, **kwargs)
def invoke(self, input: Input, config: Optional[RunnableConfig] = None, **kwargs: Any) -> Output:
return self.active_model.invoke(input, config, **kwargs)
# Example of subclasses creation
class RandomMultiChatModel(BaseMultiLanguageModel[PromptValue]):
@property
def active_model(self) -> BaseLanguageModel:
choice = randint(0, len(self.language_models) - 1)
print(f"Using LLM: {choice}")
return self.language_models[choice]
class RoundRobinMultiChatModel(BaseMultiLanguageModel[PromptValue]):
index: int = 0
@property
def active_model(self) -> BaseLanguageModel:
self.index = (self.index + 1) % len(self.language_models)
print(f"Using LLM: {self.index}")
return self.language_models[self.index]
# Usage
llm1 = ChatOpenAI(openai_api_key=OPENAI_API_KEY_1)
llm2 = ChatOpenAI(openai_api_key=OPENAI_API_KEY_2)
round_robin_multi_llm = RoundRobinMultiChatModel(language_models=[llm1, llm2])
round_robin_multi_llm.predict("Hello, how are you?") # use the same methods as BaseLanguageModel
```
This is working with simple examples but I'm not sure this inheritance hierarchy is the best so any help would be appreciated to define the best solution :) | MultiLanguageModel: work with multiple LLM with the interface of a single one | https://api.github.com/repos/langchain-ai/langchain/issues/12656/comments | 10 | 2023-10-31T16:39:54Z | 2024-02-26T16:07:18Z | https://github.com/langchain-ai/langchain/issues/12656 | 1,970,867,010 | 12,656 |

langchain.debug = True

llm = OpenAI(temperature=0, verbose=True)

)
tools = [events_tool]
agent = initialize_agent(
tools, llm, agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION, verbose=True
)
agent.run("What happened yesterday?")
```

llm = get_watsonx_predictor(

The `Observation:` text is being passed into the tool. For simple tools like search engines, this often is not a problem. However, when your tool expects a structured input, you sometimes end up with tool input like the following:
```
"foo,bar
Observation:"
```
This results in the tool attempting to do something like splitting on `,` and then the second part of the resulting array is:
```
bar
Observation:
```
Which definitely breaks the tool.
### Expected behavior
The `Observation:` text should definitely not be passed as part of the tool input.
The MRKL output parser is here:
https://github.com/langchain-ai/langchain/blob/v0.0.327/libs/langchain/langchain/agents/mrkl/output_parser.py#L26-L77
The regex does appear to match the groups correctly:
https://regex101.com/r/v7Tg1n/1
It's unclear, though, why the `Observation:` text is ending up getting passed into the input.
Although, when you use newline characters (`\n`) in the string, and not actual newlines, it does appear that the `Observation` part is being caught in the group:
https://regex101.com/r/MMCvYn/1
I tried to spelunk into the code to figure out when the agent "base" calls `parse` to see why the `Observation` text would be getting passed into parse in the first place, but it seems that one possible fix here would be to modify the parse RegEx for MRKL to make sure it does NOT capture the observation component.
Changing the RegEx in the MRKL agent to the following:
```python
r"Action\s*\d*\s*:[\s]*(.*?)[\s]*Action\s*\d*\s*Input\s*\d*\s*:[\s]*(.*)Observation:"
```
And then modifying the tool input strip:
```python
if action_match:
action = action_match.group(1).strip()
action_input = action_match.group(2)
tool_input = action_input.strip()
```
fixes the issue if "Observation" got passed in, but I am assuming that `parse` shouldn't have gotten this in the first place. | MRKL agent is passing "Observation" text to tools when using non-OpenAI LLMs and breaks structured input tools | https://api.github.com/repos/langchain-ai/langchain/issues/12645/comments | 9 | 2023-10-31T15:55:50Z | 2024-07-04T08:07:06Z | https://github.com/langchain-ai/langchain/issues/12645 | 1,970,785,521 | 12,645 |

Similar errors for `abatch` with `max_concurrecy`.

```
config = {**config[0], "max_concurrency": None} # no list is needed
```

| I am trying to use Langchain information extraction chain with OpenAI. Firstly, I am reading a PDF file having some text about products or product. There is no specefic format of PDF, it can be in any format like, there can be only one product on one page or one product can be on two pages or there can be 10 products on one page. So it's completely random. How can I extract the the useful information (some key attributes) for all the products. Currently, I am using Pydantic to validate the output schema and I am using `PyPDFLoader` to load the pdf and then using the `load_and_split`.
```
loader = PyPDFLoader(file_path=file_path)
pages = loader.load_and_split()
```
And then I am looping on the pages like this:
```
llm = ChatOpenAI(temperature=0, model=model_name, openai_api_key=key)
chain = create_extraction_chain(schema, llm)
for index in range(0, len(pages)):
output = chain.run(pages[index])
results.append(output)
```
How can I run the extraction in such a way that it should be completely automated, currently, it is just extracting information from one page and then other and then other. | Langchain Information Extraction | https://api.github.com/repos/langchain-ai/langchain/issues/12636/comments | 7 | 2023-10-31T14:32:45Z | 2024-03-08T16:39:02Z | https://github.com/langchain-ai/langchain/issues/12636 | 1,970,609,183 | 12,636 |

### Reproduction
I want to keep generated cypher queries in the memory to feed into Question/Answer LLM which leads better understanding of the context. Following example helps to reproduce error (I am not providing prompt details etc.).
* I initialize a ConversationBufferMemory to keep both question-answer as well as generated cypher queries.
```python
graph = get_neo4j_graph(neo4j_url, neo4j_db_name, neo4j_username, neo4j_password)
custom_cypher_prompt = generate_custom_cypher_prompt()
custom_qa_prompt = generate_custom_qa_prompt()
# First I did not give any input key to Memory but it gives error when there is multiple input in the prompt template
# 'question' input_key makes it work for cypher_llm and qa_llm but fails in GraphCypherQAChain
# Since GraphCypherQAChain default input_key is 'query'
memory = ConversationBufferMemory(memory_key="chat_history", input_key='question')
readonlymemory = ReadOnlySharedMemory(memory=memory)
graph_chain = GraphCypherQAChain.from_llm(
graph=graph,
cypher_llm=ChatOpenAI(temperature='0', model='gpt-4', openai_api_key=openai_api_key),
qa_llm=ChatOpenAI(temperature='0.5', model='gpt-3.5-turbo-16k', openai_api_key=openai_api_key),

# Return intermediate steps from the Cypher QA Chain

| ### Feature request
Hi there,
Thanks you so much for this awesome library!
I have a suggestion that might improve the AzureChatOpenAI class.
In my company we use AzureChatOpenAI where the initialization of a `chat` object looks like this:
```
os.environ["OPENAI_API_KEY"] = get_token().token
return AzureChatOpenAI(
openai_api_base=AZ_OAI_API_BASE_GPT_4,
openai_api_version="2023-05-15",
deployment_name=AZ_OAI_DEPLOYMENT_ID_GPT_4,
openai_api_type="azuread",
)
```
The problem is that the get_token function returns a token with a ttl of 60 minutes.
This requires us to recreate the chat object before the expiration reaches.
I think it would be great if you could add an optional function as an argument which the AzureChatOpenAI class will trigger in the retry logic incase there is a 401 API error.
Something that looks like this:
```
class AzureChatOpenAI(ChatOpenAI):
# ..... other properties
token_refresh_function: Optional[Callable[[], str]] = None
# call this on the retry function...
def _refresh_token_if_needed(self):
if self.token_refresh_function:
new_token = self.token_refresh_function()
if new_token:
self.client.api_key = new_token
```
### Motivation
The Azure models might have a more strict security requirements where the open_api key is a token with a short ttl.
### Your contribution
I would love to help just don't have the time right now, but I shared a few snippets that might help.. | Add an optional get_token function argument to AzureChatOpenAI to be called on retry | https://api.github.com/repos/langchain-ai/langchain/issues/12632/comments | 1 | 2023-10-31T13:46:03Z | 2024-02-06T16:10:06Z | https://github.com/langchain-ai/langchain/issues/12632 | 1,970,512,615 | 12,632 |

| ### Issue you'd like to raise.
I have created a retrieval QA project. In this project, I want to add memory to LLM so that it can also remember the previous chat. I have configured the LLM not to answer from its own knowledge but from the context I provided, and it is working fine. However, when I add memory to it, it starts to answer from its own knowledge if it is out of context. I just want the LLM to answer based on the context, remember the previous chat, and if the answer is out of context, it should simply state that it is out of context or something similar. Kindly help me or suggest me something which can work.

(my local host heart beats well)
Try the same code with a small piece of business-related conversation doc(~ 1k words) w/ StuffDocumentsChain returns something relevant, but load_summarize_chain only gives

More problem comes, when I double the size on my test doc(4k words, definitely have to be>4096 tokens, that's the point of using summarization), it returns Error 1 and Error 2 mentioned at the beginning, same as attempting replication langchain documentation, so get the trouble it is not able to process long doc gain.

| Hi! Usually I process English documents, but I recently had to process files in Portuguese and UnstructuredFileLoader can't deal with it. I loose characters such as ç, é, í, ã, õ, etc. It doesn't matter if its PDF, HTML or DOCX. Is there a way to encode it properly?

### Reproduction
#### Steps to Reproduce:
1. Query the Bing Search tool with a specific text : `{"keywords":["Everyday C%23", "advanced"]} site:https:learn.microsoft.com'.`
2. Observe that the tool fails to return results and instead displays the message `webPages`.
#### Actual Behavior:
The Bing API fails to return relevant results if there are no matches. In these situations, the API omits the `webPages` property from the response.
### Expected behavior
#### Expected Behavior:
The Bing Search tool should return relevant results for any given keyword or a message that the results can not be found. | [Bing Search Wrapper] KeyError Exception 'webPages' in LangChain Bing Search Tool: Recurring Bug Impacting Search Results | https://api.github.com/repos/langchain-ai/langchain/issues/12575/comments | 4 | 2023-10-30T18:08:40Z | 2024-02-11T16:08:06Z | https://github.com/langchain-ai/langchain/issues/12575 | 1,968,948,475 | 12,575 |

| ### Issue you'd like to raise.
I have a ConversationSummaryBufferMemory object which stores the chat history between human and AI. One such history looks like
```python
[HumanMessage(content='Hi', additional_kwargs={}, example=False),
AIMessage(content='Hi, how can I help you?', additional_kwargs={}, example=False),
HumanMessage(content='What is TPA', additional_kwargs={}, example=False),
AIMessage(content='TPA stands for TPA', additional_kwargs={}, example=False)]
```
I am looking a list of tuples of messages like
```[('Hi', 'Hi, how can I help you?'), ('What is TPA','TPA stands for TPA')]```
How can I do that?

| ### Issue with current documentation:
I have a faiss vector store that I created before, when I print it it appears as <langchain.vectorstores.faiss.FAISS object at 0x0000022B3DFBBB50>. Then, I create a new faiss vector store and when I print it, it appears as <langchain.vectorstores.faiss.FAISS object at 0x0000022B7D0F4810>. I want to merge these two faiss objects, so I tried the merge_from method. However, when I try merge_from, vector store appears None. Here is my code:
vector_store = FAISS.from_texts(text_chunks, embeddings,
metadatas=[{"source": f"{created_pkl_name}:{i}"} for i in
range(len(text_chunks))])
print("vector_store_new: ",vector_store) # <langchain.vectorstores.faiss.FAISS object at 0x0000022B7D0F4810>
if os.path.exists(faiss_path_all):
with open(faiss_path_all, 'rb') as faiss_file_all:
all_data = pickle.load(faiss_file_all)
print("all_data: ", all_data) # <langchain.vectorstores.faiss.FAISS object at 0x0000022B3DFBBB50>
all_data = all_data.merge_from(vector_store)
print(all_data) # None
How I can solve this problem? Is there another way for merge two faiss vector stores?
### Idea or request for content:
From the example (https://python.langchain.com/docs/integrations/vectorstores/faiss?highlight=FAISS#merging) I tried the same way, but still it doesn't work for me. | After doing merge_from with Faiss, vector store appears as None. | https://api.github.com/repos/langchain-ai/langchain/issues/12570/comments | 2 | 2023-10-30T17:06:45Z | 2024-05-13T16:55:55Z | https://github.com/langchain-ai/langchain/issues/12570 | 1,968,841,818 | 12,570 |

| ### Update: Pull request here: #12586
Video Demo: [https://youtu.be/wspB6QbDzBc](https://youtu.be/wspB6QbDzBc)
### Feature request
Description:
I have developed a class `HuggingFaceTextGenInferenceAuto` to automate the process of managing Docker inference server containers for the `HuggingFaceTextGenerationInference` LLM. It essentially acts as a factory to create an instance of `HuggingFaceTextGenInference` via the `from_docker` classmethod. This class can create, reuse, or recreate containers as-needed based on parameter changes.
The objective is to simplify the management of HuggingFace TextGen inference servers, and allow users to spin up Docker containers for model inference with ease. The code also contains methods to handle the health checks, wait for model downloads, and ensure container and API readiness before proceeding.
Here is a breakdown of the main functionalities:
**Automated Docker Container Management:**
* Create, reuse, or recreate Docker containers for HuggingFace TextGen inference.
* Auto-increment host port if the specified port is unavailable.
* Provide a health check and wait for model download completion.
**Parameter Management:**
* Handle Docker parameters for textgen-inference-server and HuggingFaceTextGenInference parameters with Pydantic models.
* Provide methods to convert parameters to dictionaries for easier management.
Validate parameters and create new containers based on parameter diffs
**Utility Methods:**
* Methods to get the model name, image tag, container, etc., from various inputs.
* Utility methods for converting shared memory size, checking port availability, and finding available host ports.
The code is ready and I plan to submit a pull request for review and integration. I believe this feature will be a valuable addition to the Langchain library, allowing for easier rapid prototyping of LLM-powered applications.
### Motivation
1. **Reduce Manual Intervention:**
- Minimize the steps a user has to take to spin up a HuggingFace TextGen Inference server, making the process faster and less error-prone.
- By automated handling of health checks, waiting for model downloads, and ensuring the readiness of the container and API, we aim to expedite prototyping of LLM powered applications. (We expect this will be especially useful for things like, e.g. auto-evaluation / parameter searches for LLM apps.)
2. **Ensure Consistency:**
- Provide a structured way to handle parameters and configurations for both container and Langchain LLM wrapper

### Reproduction
When you try the tutorial:
```
index_name = "vector" # default index name
keyword_index_name = "text_index" # default keyword index name
store = Neo4jVector.from_existing_index(
OpenAIEmbeddings(),
url=url,
username=username,
password=password,
index_name=index_name,
keyword_index_name=keyword_index_name,
search_type="hybrid",
)
```
It produces an error because in fact the keyword index is not created yet:
`ValueError: The specified keyword index name does not exist. Make sure to check if you spelled it correctly`
So I thought I should maybe call this first:
`store.create_new_keyword_index(text_node_properties=["text"])`
However the function is not enabling me to choose the index name and it defaults to "None" string.
I suggest the last method should include the name of the index.
### Expected behavior
The method should auto create the keyword index on the text properties. | Neo4J keyword index creation problem | https://api.github.com/repos/langchain-ai/langchain/issues/12553/comments | 3 | 2023-10-30T13:04:58Z | 2024-02-08T16:11:56Z | https://github.com/langchain-ai/langchain/issues/12553 | 1,968,312,500 | 12,553 |

### Reproduction
from langchain.agents import create_sql_agent
from langchain.agents.agent_toolkits import SQLDatabaseToolkit
from langchain.sql_database import SQLDatabase
from langchain.llms.openai import OpenAI
from langchain.agents import AgentExecutor
from langchain.agents.agent_types import AgentType
from langchain.chat_models import ChatOpenAI
db = SQLDatabase.from_uri("sqlite:///../../../../../notebooks/Chinook.db")
toolkit = SQLDatabaseToolkit(db=db, llm=OpenAI(temperature=0))
agent_executor = create_sql_agent(
llm=OpenAI(temperature=0),
toolkit=toolkit,
verbose=True,
agent_type=AgentType.ZERO_SHOT_REACT_DESCRIPTION,
)
agent_executor.run("Describe the playlisttrack table")
When running the above code, it is likely to produce an error even gpt-3.5 model is used. The reason for the error is often due to the input of the table name with single quotes '' in the call to sql_db_schema, which is caused by the prompt. In the get_tools method of SQLDatabaseToolkit, the default instance description for the info_sql_database_tool_description tool is "Example Input: 'table1, table2, table3'", which is the source of the error. The correct description should be "Example Input: table1, table2, table3". Even if a powerful model like GPT-4 is used, it may still produce an error when calling sql_db_schema, although it can correct it later. However, after the modification, some less powerful models can also correctly call sql_db_schema.
I found the same issue reported by someone else and was troubled by it. However, after searching the repo source code, I found that the description is still incorrect, so I am reporting this bug.
### Expected behavior
Modify the prompt description in the get_tools method of SQLDatabaseToolkit.

| ### Issue you'd like to raise.
Im trying to use an agent as a router for two retrievals. I also want it to have memory so im using the conversational agent with two RetrievalQA chains and ConversationBufferWindowMemory.
Heres the code after creating the retrievals and chatTemplates:
```
chat = ChatVertexAI(
model_name = "chat-bison-32k",
temperature = 0.5,
top_p = 0.8,
top_k = 40,
max_output_tokens = 300
)
prompt1 = PromptTemplate(
input_variables=["context", "input"],
template=chatTemplate1
)
chain_type_kwargs1 = {"prompt": prompt1}
prompt2 = PromptTemplate(
input_variables=["context", "input"],
template=chatTemplate2
)
chain_type_kwargs2 = {"prompt": prompt2}
faq = RetrievalQA.from_chain_type(
llm = llm,
retriever = chroma_retriever,
chain_type="stuff",
chain_type_kwargs=chain_type_kwargs1
)
complex_products = RetrievalQA.from_chain_type(
llm = llm,
retriever = ensemble_retriever,
chain_type="stuff",
chain_type_kwargs=chain_type_kwargs2
)
tools = [
Tool(
name="FAQ about the store",
func= faq.run,
description="useful for when you need to answer questions about related to frequently asked questions. This tool provides information on business hours and store location. To use, input a well-formulated question.",
),
Tool(
name="Product information",
func=complex_products.run,
description="useful for when you need to answer questions about certain products that the costumer needs. Input should be a fully formed question.",
),
]
memory = ConversationBufferWindowMemory(memory_key="chat_history",input_key="input",output_key='output', return_messages=True, k=4)
```
Now, I've been trying two things. The first one is to call my agent with the memory directly. I tried it with and without using .run():
```
agent = initialize_agent(
tools = tools,
llm = chat,
agent = AgentType.CONVERSATIONAL_REACT_DESCRIPTION,
verbose=True,
handle_parsing_errors=True,
max_iterations = 3,
early_stopping_method = 'generate',
memory = memory
)
result = agent("What are the closing hours?")
result["output"]
```
but with some questions, not all, i get the following error:
```
> Entering new AgentExecutor chain...
Thought: Do I need to use a tool? Yes
Action: FAQ about the store

### Suggestion:
- Maybe using a template for the agent can work? I dont know if its possible, but im also having trouble forcing it to use only the tools to search the info or else answer that it doesnt know.
- Using LCEL to add a parser but im not familiar with LCEL.

When trying to reproduce the example of the Scoring evaluator [https://python.langchain.com/docs/guides/evaluation/string/scoring_eval_chain#usage-without-references] with the next code
`evaluator = load_evaluator("labeled_score_string", criteria=criteria, llm=llm, normalize_by=10)
eval_result = evaluator.evaluate_strings(prediction="You can find them in the dresser's third drawer.", reference="The socks are in the third drawer in the dresser", input="Where are my socks?")`
I'm getting the error `ValueError: Invalid output: . Output must contain a double bracketed string with the verdict between 1 and 10.`

Hi,
I build a chatbot using conversationchain. I want to final output to be steamed. I tried StreamingStdOutCallbackHandler and FinalStreamingStdOutCallbackHandler.
The problem with StreamingStdOutCallbackHandler is that it also prints out the memory of the chain.
The problem with FinalStreamingStdOutCallbackHandler is that it did print the final output, but the output is just printed out at once rather than streamed.
How can I fix it?
Thanks,

Okay I have tried both SQL database chain and create SQL agent from agents and what i have seen is that after run and it returns zero records from the database and LLM gives the output from its own. So basically I have only one fruit in my database and if I ask what fruit contains vitamin c which is not in the database and it fetch me the result from its own knowledge base. I tried adding the instructions in the prompt like if query return zero records or observation is empty or the result of the SQL. Query is empty, Do not share anything on your own And just convey the message to the user that for your certain filter criteria that is no records Try different query or elaborate your request but it doesn't seem to be working. is there anyting we can do to fix it?

| ### Feature request
parse the text in a pdf to determine whether it contains header fields such as From:, To:, Date: etc which make it likely that the original data was an email. if so, return the contents of those fields as Document metadata which can, for example, be used as metadata in a database. (reopening of https://github.com/langchain-ai/langchain/issues/8094)
### Motivation
Sometimes it as important to know who said what to whom when as it is to determine what actual facts are. Investigative reporting is one example. There are adequate tools to retrieve email and its metadata from Gmail or Exchange. A similar tool for email which has been saved as a collection of PDFs which parses and retrieves the metadata will make these document collections more accessible and useful.
### Your contribution
I have created a pdf to email tool in the proper format to incorporated with existing langchain document loaders. It's at https://github.com/tevslin/emailai, There's been enough interest so that I'm forking, linting, and will submit a pr. | email with metadata from pdfs | https://api.github.com/repos/langchain-ai/langchain/issues/12494/comments | 2 | 2023-10-28T21:01:17Z | 2024-02-06T16:11:56Z | https://github.com/langchain-ai/langchain/issues/12494 | 1,966,738,613 | 12,494 |

| ### Feature request
Module: langchain.chains.conversational_retrieval.base.ConversationalRetrievalChain
`qa = ConversationalRetrievalChain(
retriever=self.vector_store.as_retriever(), # type: ignore
combine_docs_chain=self.doc_chain,
question_generator=LLMChain(
llm=self.answering_llm, prompt=CONDENSE_QUESTION_PROMPT
),
verbose=False,
)`
`model_response = qa(
{
"question": user_message,
"chat_history": formatted_chat_history,
"custom_personality": self.prompt_content,
}
)`
I would like that the model_response (the result from called the ConversationalRetrievalChain) returns the document ids in which the answer is based
### Motivation
My motivation is to be able to document which documents is the model basing its responses to further analyse and use this input for user experience improvement and transparency.
One possibility would be to use the _get_docs method under ConversationalRetrievalChain, but this would imply calling twice the model
### Your contribution
As of now the model_response returns:
`{'question': 'Who won the Olympics in 92?', 'chat_history': [()], 'custom_personality': 'xxxxxx
', 'answer': 'The US won the Olympics'}`
My proposal would be:
`{'question': 'Who won the Olympics in 92?', 'chat_history': [()], 'custom_personality': 'xxxxxx
', 'answer': 'The US won the Olympics', 'documents_source': [Document(), Document()...]}` | Get document ids from ConversationalRetrievalChain's reponse | https://api.github.com/repos/langchain-ai/langchain/issues/12479/comments | 2 | 2023-10-28T11:44:24Z | 2023-10-29T16:42:00Z | https://github.com/langchain-ai/langchain/issues/12479 | 1,966,563,554 | 12,479 |

Guys,
Just to make it more 'generic' instead of path, could you not make it file handle ? Any reason it has to be file path ?

File handles are anyway used in the codes once file opened. sounds like make sense to use that rather than file/path

Currently: api-based models that pass rate limits raise an error and abort.
Desirable: sending api requests together in parallel, in a way that tracks their global token usage and response times, and waits as needed to avoid the rate limit.

I've successfully generated and stored embeddings for PDF documents, Confluence content, and URL data within a single 'embeddings' folder using ChromaDB. However, I'm looking to enhance the functionality and add the ability to delete and re-add PDF/URL/Confluence data from this combined folder while preserving the existing embeddings.
I believe this feature would significantly improve the versatility of the application and make it more user-friendly. Any guidance or contributions in implementing this functionality would be greatly appreciated.

| ### Issue you'd like to raise.
I'm building an agent to interact with neo4j with a custom chain (I'm aware of the chains already implemented for this case), my problem comes when I try to pass multiple arbitrary arguments to my tool. What i want to know is how can I propagate arguments from the creation of the agent / tool, and how to propagate arguments thorugh the execution of the AgentExecutor. Here is my code so far.
I have a chain that I use as a tool:
```
class LLMCypherGraphChain(Chain, BaseModel):
input_key: List[str] = ["question", "content_type"]
```
Then i create my AgentExecutor and use the initialize_agent method, I instanciate the class previously defined and use the run method as a function to execute.
```
class GraphAgent(AgentExecutor):
@classmethod
def initialize(cls,...)
cypher_tool = LLMCypherGraphChain(
llm=llm,
input_key=["question", "content_type"],
graph=graph,
verbose=verbose,
memory=readonlymemory
)
# Load the tool configs that are needed.
tools = [
Tool(
name="Cypher search",
func=cypher_tool.run,
description="""
Utilize this tool to search within a database, specifically designed to answer x questions.
This specialized tool offers streamlined search capabilities to help you find the movie information you need with ease.
Input should be full question.""", # noqa
)
]
agent_chain = initialize_agent(
tools,
llm,
agent=AgentType.STRUCTURED_CHAT_ZERO_SHOT_REACT_DESCRIPTION,
verbose=verbose,
memory=memory,
return_intermediate_steps=True
)
def run(self, *args, **kwargs):
return super().run(*args, **kwargs)
```
So at this point I only need to instanciate the agent and run it.
```
self.agent_executor = GraphAgent.initialize(
...
)
res = self.agent_executor({"question": "my question",
"input": "my question",
"random_param": "my other param"})
```
So the problem is that I have this agent stored in a variable to avoid recreating it, that means self.agent_executor is only initialized once but then I want to be able to propagate the question and random_param to my tool.
I have seen some posts about passing parameters to tools but none of them actualy solved this problem. I am not sure if using agent_kwargs in the initialize_agent would be a solution (I'm not quiet sure how that propagates to the tools) but that only would happen once, when the instanciation is done.
Right now Im getting this error, so I am not understanding how arguments are propagated:
ERROR:root:A single string input was passed in, but this chain expects multiple inputs ({'question', 'content_type'}). When a chain expects multiple inputs, please call it by passing in a dictionary, eg `chain({'foo': 1, 'bar': 2})`
Any help is appreciated! thanks!

| **Accessing ChromaDB Embedding Vector from S3 Bucket**
**Issue Description:**
I am attempting to access the ChromaDB embedding vector from an S3 Bucket and I've used the following Python code for reference:
```python
# Now we can load the persisted database from disk, and use it as normal.
vectordb = Chroma(persist_directory=persist_directory, embedding_function=embedding)
```
However, I'm uncertain about the steps to follow when I need to specify the S3 bucket path in the code.

- What specific modifications or additions are required to access the embedding vector from an S3 Bucket?
- Are there any configuration changes needed to integrate S3 access seamlessly?

I am using the below code to fetch contents for user queries.
db = PGVector(

embedding_function=embeddings,
)
retriever = db.as_retriever(

while its working fine generally, in some case, the context brought does not represent the contents in the table. While i can query the same content using a simple query with select * from langchain_pg_embedding where document like '%keyword%' fetches records, it fails to bring relevant contents using langchain. I have removed duplicate records in the table, to see if that improves the search, but no improvement. Help me understand the causes and solution please.

### Reproduction
1. Create a retrieval chain with streaming:
```
this.chain = RetrievalQAChain.fromLLM(this.model, this.store.asRetriever(), {
prompt: PromptTemplate.fromTemplate(this.prompt),
returnSourceDocuments: true,
stream: true
});
```
2. Call `stream()` on the chain:
```
const response = await this.chain.stream({
query: question,
callbacks: [
{
handleLLMNewToken(token) {
onChunkCallback(token);
},
handleLLMEnd(result, res2) {
onEnd(result, res2);
}
},
]
});
```
3. View the `sourceDocuments` property on the returned response, and set `verbose: true` on the chain and observe the chain output shows a `sourceDocuments` property that is an empty array.
### Expected behavior
The `sourceDocuments` property is populated the same way it is when not using streaming which shows the source documents the model used to generate the answer. | sourceDocuments are not returned when streaming with RetrievalQAChain but returns properly when *not* using streaming | https://api.github.com/repos/langchain-ai/langchain/issues/12400/comments | 4 | 2023-10-27T03:53:38Z | 2024-06-10T06:23:52Z | https://github.com/langchain-ai/langchain/issues/12400 | 1,964,716,724 | 12,400 |

```python
from langchain.document_loaders import Docx2txtLoader
def main():
file = 'elon_doc.docx'
loader = Docx2txtLoader(file)
text = loader.load()
print(text)
if __name__ == '__main__':
main()

| ### Feature request
Self-RAG is a new open-source technique (MIT license) that implements:
1. **Adaptive retrieval via retrieval tokens:** allows you to fine-tune LLMs to output `[Retrieval]` tokens mid-generation to indicate when to perform retrieval. It has been empirically shown to improve open-source models to match ChatGPT level of performance in RAG tasks.
2. **Critique tokens:**
- w_rel (default 1.0): This variable controls the emphasis on relevance during beam search.
- w_sup (default 1.0): This variable controls the emphasis on support from the document during beam search.
- w_use (default 0.5): This variable controls the emphasis on overall quality during beam search.
Requirements:
- make it compatible with vLLM for inference such that any fine-tuned Self-RAG model can be deployed in a framework with PagedAttention implemented.
- able to query vector database

| ### Issue you'd like to raise.
I have been experimenting with SelfQueryRetriever. I am trying to use it to find a book based on a query.
For example:
"Find me a book that was written by Hayek".
The LLM correctly creates the query:
"query='Hayek' filter=Comparison(comparator=<Comparator.EQ: 'eq'>, attribute='Autor', value='Hayek') limit=None"
But, the problem is that in my metadata, I have full names of authors, for example:
"Autor": "Friedrich A. Hayek"
And because the comparator is `eq`, therefore equality, the retriever does not find my book. A solution would be:
1. Add `contains` operator to the SelfQueryRetriever and allows us to turn it on/off using some parameter. We could do this by ourselves if you gave us access to the prompt that is being used to generate the query. I already requested this in a [separate issue](https://github.com/langchain-ai/langchain/issues/11735).
2. Allow using of lists (so I could split the full name into an array of names). However [LangChain documentation](https://python.langchain.com/docs/modules/data_connection/retrievers/self_query/) says that it is possible to use lists for attributes, the testing shows that it is not possible. When trying to use a list, you will get the following error:
`ValueError: Expected metadata value to be a str, int, float or bool, got ["Friedrich", "A.", "Hayek"] which is a <class 'list'>`
### Suggestion:
Please allow one of the two solutions. Either using `contains` with SelfQueryRetriever or allow using lists. | Issue: SelfQueryRetriever and contains('string') | https://api.github.com/repos/langchain-ai/langchain/issues/12370/comments | 1 | 2023-10-26T20:45:02Z | 2023-11-05T16:45:47Z | https://github.com/langchain-ai/langchain/issues/12370 | 1,964,343,443 | 12,370 |
