| I am trying to use the `add_texts` method on a previously instanciated Neo4jVector object for setting the node_label.
The scenario is that I am processing different types of text and want to create different nodes accordingly. Because I am handling the database connection somewhere else in my code, I don't want to establish the connection to the database when embedding texts.
```python
[...]
# initialize vector store
self.vector_store = Neo4jVector(
embedding=self.embeddings_model,
username=neo4j_config['USER'],
password=neo4j_config['PASSWORD'],
url=neo4j_config['URI'],
database=neo4j_config['DATABASE'], # neo4j by default
index_name="vector", # vector by default
embedding_node_property="embedding", # embedding by default
create_id_index=True, # True by default
)
[...]
# embed text
created_node = self.vector_store.add_texts(
[text],
metadatas=[
{
"label": [node_label]
}
],
embedding=self.embeddings_model,
node_label=node_label, # Chunk by default
text_node_property=text_node_property, # text by default
)
```
Currently the `node_label` property is overwritten with the default value and not respected when used as a parameter in **kwargs.
https://github.com/langchain-ai/langchain/blob/eb572f41a65c9636b9e0e5a5fb4210a00a67a353/libs/langchain/langchain/vectorstores/neo4j_vector.py#L125
https://github.com/langchain-ai/langchain/blob/eb572f41a65c9636b9e0e5a5fb4210a00a67a353/libs/langchain/langchain/vectorstores/neo4j_vector.py#L450
According to the Docstring, the function is supposed to accept vectorstore specific parameters:
https://github.com/langchain-ai/langchain/blob/eb572f41a65c9636b9e0e5a5fb4210a00a67a353/libs/langchain/langchain/vectorstores/neo4j_vector.py#L458
In order to conform with this, I added this function:
```python
def update_vector_store_properties(self, **kwargs):
# List of vector store-specific arguments we want to check and potentially update
vector_store_args = ["node_label", "text_node_property", "embedding_node_property"]
# Iterate over these arguments
for arg in vector_store_args:
# Check if the argument is present in kwargs
if arg in kwargs:
# Update the corresponding property of the Neo4jVector instance
setattr(self, arg, kwargs[arg])
```
I then modified `add_embeddings` like this:
```python
def add_embeddings(
self,
texts: Iterable[str],
embeddings: List[List[float]],
metadatas: Optional[List[dict]] = None,
ids: Optional[List[str]] = None,
**kwargs: Any,
) -> List[str]:
"""Add embeddings to the vectorstore.
Args:
texts: Iterable of strings to add to the vectorstore.
embeddings: List of list of embedding vectors.
metadatas: List of metadatas associated with the texts.
kwargs: vectorstore specific parameters
"""
if ids is None:
ids = [str(uuid.uuid1()) for _ in texts]
if not metadatas:
metadatas = [{} for _ in texts]
self.update_vector_store_properties(**kwargs)
[...]
```
Don't really know if this is a missing feature or a bug or if I am just using the Vectorstore wrong, but I thought I'd leave this here in case it might be the desired behavior.

| ### Feature request
Loaders are designed to load a single source of data and transform it to a list of Documents. If several sources are to be processed, it is up to the developer to call the Loader several times.
The idea is to propose a new `BatchLoader` object that could simplify this task and enable loading tasks to be launched sequentially, mutlithreaded, with mutli processor or asynchronously.
Draft idea:
```
class BatchLoader(BaseLoader):
...
def load(self, method: str = 'sequential', max_workers: int=1) -> List[Document]:
# TODO: faire ça stylé
if method == 'thread':
return self._load_thread(max_workers)
elif method == 'process':
return self._load_process(max_workers)
elif method == 'sequential':
return self._load_sequential()
elif method == 'async':
return asyncio.run(self._async_load())
else:
raise ValueError(f'Invalid method {method}')
...
# Call it with a Loader constructor callable and a set of arguments
batch_loader = BatchLoader(TextLoader, {"file_path": [f"file_{i}.txt" for i in range(1000)]})
```
### Motivation
In most real use case we need to load several Data Sources, combine their outputs and work with them (e.g. store in a vector store). Some use cases also require to wait for I/O intensive tasks or tasks you want to parallelized, so having a Meta loader that wrap this complexity for you could be a good idea.

| ### Feature request
We propose the addition of Google Scholar querying with the serpapi, as google Scholar is a prominent platform for accessing academic and scholarly articles.
### Motivation
Google scholar is a crucial resource for researchers, students, and professionals in various fields. Integrating Google Scholar querying with serpapi would provide users with the ability to programmatically retrieve search results from Google Scholar, giving the llms more better/more reliable information to work with.
### Your contribution
We intend to submit a pull request for this issue at some point in November. | Add support for google scholar querying with serpapi | https://api.github.com/repos/langchain-ai/langchain/issues/11505/comments | 4 | 2023-10-06T23:45:22Z | 2023-11-13T20:13:57Z | https://github.com/langchain-ai/langchain/issues/11505 | 1,931,050,084 | 11,505 |

### Reproduction
I have a simple web page summarize function basacilly followed example
```python
llm = OpenAI(temperature=0)
loader = WebBaseLoader(link)
docs = loader.load()
MAP_PROMPT = PromptTemplate(
template="""Write a concise summary of the following web page(keep all identifiable information about the main entities):
{text}
CONCISE SUMMARY:
""",
input_variables=["text"],
)
REDUCE_PROMPT = PromptTemplate(
template="""Based on the following text, write a concise summary(keep all identifiable information about the main entities)):
{text}
CONCISE SUMMARY:
""",
input_variables=["text"],
)
chain = load_summarize_chain(
llm,
chain_type="map_reduce",
return_intermediate_steps=True,
map_prompt=MAP_PROMPT,
combine_prompt=REDUCE_PROMPT,
)
text_splitter = RecursiveCharacterTextSplitter()
docs = text_splitter.split_documents(docs)
if len(docs) == 0:
return ""
result = chain(
text_splitter.split_documents(documents=docs),
return_only_outputs=True,
)
logging.debug(result)
return result["output_text"]
```
my program loaded in a pdf url link (https://www.fiserv.com/content/dam/fiserv-ent/final-files/marketing-collateral/case-studies/regions-bank-case-study-0623.pdf)
web based loader created 1 page document with a large number of tokens (13524539 characters)
I then started to get openai library error:
```
error_code=rate_limit_exceeded error_message='Rate limit reached for default-text-davinci-003 in organization org-a6hHivOPvKe9X60G8E6YqM5m on tokens_usage_based per min. Limit: 250000 / min. Current: 245411 / min. Contact us through our help center at help.openai.com if you continue to have issues.' error_param=None error_type=tokens_usage_based message='OpenAI API error received' stream_error=False
```
langchain kept retrying on this error definetly more than the default 6 times, I had `14` retry log from langchain in my terminal.
I think this is a quite critical bug, my OpenAI usage limit blew up the $120 limit under 10mins because of this.
### Expected behavior
retry limit should kick it to short circuit this situation or there should be some other method to prevent unexpected length of document being passed to openAI | Retry limit is not respected | https://api.github.com/repos/langchain-ai/langchain/issues/11500/comments | 2 | 2023-10-06T21:37:53Z | 2024-02-07T16:22:18Z | https://github.com/langchain-ai/langchain/issues/11500 | 1,930,961,933 | 11,500 |

| ### Feature request
The Redis Vectorstore `add_documents()` method calls `add_texts()` which embeds documents one by one like:
```
embedding = (
embeddings[i] if embeddings else self._embeddings.embed_query(text)
)
```
The `add_documents()` method would seem to imply that it is a good way to jointly embed and upload a larger list of documents, but using an API call for each document as above is slow and prone to run into rate limits.
Redis `add_documents()` could pass a kwarg `from_documents=True`to `add_texts()` which would change embedding to
```
embedding = (
embeddings[i] if embeddings else self._embeddings.embed_documents(documents)
)
```
### Motivation
This would simplify the overall use of the Redis Vectorstore and would be more inline with how the example documents imply the add_documents() method should be used. Currently `add_documents()` is not suitable for something like a csv or a long list of smaller documents unless it is used like:
```
add_documents(
documents=split_documents,
embeddings=embedder.embed_documents(texts),
)
```
### Your contribution
I could create a PR for this issue if it makes sense! | Redis Vectorestore.add_documents() should use embed_documents() instead of embed_query() | https://api.github.com/repos/langchain-ai/langchain/issues/11496/comments | 3 | 2023-10-06T20:31:55Z | 2024-02-12T16:12:09Z | https://github.com/langchain-ai/langchain/issues/11496 | 1,930,899,139 | 11,496 |

### Reproduction
Hey!
I have been trying to reproduce the langchain's pgvector official documentation without success. For some reason when I try to use async await around PGVector it throws an error.
`const pgvectorStore = await PGVectorStore.initialize(
new OpenAIEmbeddings(),
config
);`
This is the official documentation.
`export const pgvectorStore = await PGVectorStore.initialize(
new OpenAIEmbeddings(),
config
);`
This is my version.
I'm using TypeScript and it recommends to change both module and target versions inside compilerOptions, **done both without success.**
`Top-level 'await' expressions are only allowed when the 'module' option is set to 'es2022', 'esnext', 'system', 'node16', or 'nodenext', and the 'target' option is set to 'es2017' or higher.ts(1378)`
This is the output if I try to run the code:
`node:internal/process/esm_loader:108
internalBinding('errors').triggerUncaughtException(
^
Error: Transform failed with 1 error:

| ### Issue you'd like to raise.
The llm loader `load_llm_from_config` defined [here](https://github.com/langchain-ai/langchain/blob/master/libs/langchain/langchain/llms/loading.py#L12) only returns `BaseLLM`s. There is no equivalent chat_model loader in langchain to load Chat Model LLMs from a config that I'm aware of.
What do you think of either extending the `load_llm_from_config` such that it returns both `BaseLLM` and `BaseChatModel`
```
load_llm_from_config(config: dict) -> Union[BaseLLM, BaseChatModel]
```
or create a chat_model loader in `langchain.chat_models.loading.py`

# Accessing the OPENAI_API_KEY KEY
import environ
DIR_COMMON = "./common"
env = environ.Env()
environ.Env.read_env(env_file=DIR_COMMON+"/.env_iveco")
# Schema
schema = {
"properties": {

"height": {"type": "integer"},
"hair_color": {"type": "string"},
},
"required": ["name", "height"],
}
# Input
inp = """Alex is 5 feet tall. Claudia is 1 feet taller Alex and jumps higher than him. Claudia is a brunette and Alex is blonde."""
# # Run chain
llm = AzureChatOpenAI(deployment_name="gpt4-datalab",model_name="gpt-4")
chain = create_extraction_chain(schema, llm,verbose= True)
print(chain.run(inp))
```
When i run i get:

### Reproduction
With GPT-3.5 turbo 16k model,
Query - What is universal workflow type?
Thought: Do I need to use a tool? Yes
Action: chat_with_datasource
Action Input: What is universal workflow type?
Observation: The Universal Workflow type represents logic flows in a system. It includes two types: Flows and Subflows.
Thought: Do I need to use a tool? No
raise OutputParserException(f"Could not parse LLM output: `{text}`")
langchain.schema.output_parser.OutputParserException: Could not parse LLM output: `Do I need to use a tool? No`
Analysis -
Although when I checked i found, its using
Langchain/agents/Conversational/prompt.py
--------------------------------------------------
FORMAT_INSTRUCTIONS = """To use a tool, please use the following format:
```
Thought: Do I need to use a tool? Yes
Action: the action to take, should be one of [{tool_names}]
Action Input: the input to the action

```

```
Thought: Do I need to use a tool? No

```"""
-----------------------------------------------------
So, when it does not get any tool to use, it should generate some response in "ai_prefix}:"may be previous response of llm/observation at last step"
but, its unable to generate any response and resulted into parser error.
However, when I run the same code with GPT-4, below is the response I get, and its able to parse the output as well, since llm is able to generate
{ai_prefix}: [Your response here] as per the prompt instruction, but GPT-3.5 model is unable to generate it.

| ### Issue you'd like to raise.
Hello,
I'm trying to change dynamically a prompt, based on the value of the context in a ConversationalRetrievalChain
```
prompt_template = """You are an AI assistant.
Use the following pieces of context to answer the question, in a precise way, at the end.
Context: {context if context else "some default: I don't have information about it"}
Question: {question}
Helpful Answer :"""
QA_PROMPT = PromptTemplate(
template=prompt_template, input_variables=["context", "question"]
)
llm = AzureChatOpenAI(
temperature=0,
deployment_name="gpt-35-turbo",
)
memory = ConversationBufferWindowMemory(
k=1,
output_key='answer',
memory_key='chat_history',
return_messages=True)
retriever = vector.as_retriever(search_type="similarity_score_threshold", search_kwargs={"score_threshold": .70})
qa_chain = ConversationalRetrievalChain.from_llm(llm=llm,
memory=memory,
retriever=retriever,
condense_question_prompt=CONDENSE_QUESTION_PROMPT,
combine_docs_chain_kwargs={'prompt': QA_PROMPT},
return_source_documents=True,
verbose=True)
```
The idea is when the retriever gets 0 documents, to have something in the context that push the model to say I don't know and don't make up and answer. I already try by adding in the prompt "if you don't know the answer don't make it up" and didn't work.
Any idea how to add a condition in the template or control the LLM based on the output of the retriever?

| ### Issue you'd like to raise.
I use Qdrant through langchain to store vectors. But I can't find any example in docs where the dataset is searched based on a previously created collection. How to load the data? I found that Pinecone has "from_existing_index" function, which probably does the thing. But Qdrant doesn't have such a function. I created my own solution using qdrant_client, but I would like to use Langchain to simplify the script. How to do it?

| ### Feature request
I am using Weaviate with ConversationalRetrievalChain
I am using `similarity_score_threshold` search type.
It will call `similarity_search_with_score` in `vectorstore/weaviate.py`
Currently it's written like this
` if not self._by_text:
vector = {"vector": embedded_query}
result = (
query_obj.with_near_vector(vector)
.with_limit(k)
.with_additional("vector")
.do()
)
else:
result = (
query_obj.with_near_text(content)
.with_limit(k)
.with_additional("vector")
.do()
)
`
The `with_additional` function can accept a list of `AdditionalProperties`
So there's no point of hardcoding to be just the vector, and let the user add the additional arguments required.
I've tested this just by changing ` .with_additional("vector")` to ` .with_additional(["vector", "certainty"] )` and it works just fine
### Motivation
I am using the Conversational Chain just because it's easier to manage than creating one. But it's limitations are apparent. I want to retrieve the scores it get which is currently not possible
### Your contribution
I don't know how to pass in the `_additional` arguments from the vectorstore.as_retriever() but just hard coding the args i want the tests worked fine. | Vectorstore and ConversationalRetrievalChain should return the certainty of the relevance | https://api.github.com/repos/langchain-ai/langchain/issues/11470/comments | 1 | 2023-10-06T10:29:22Z | 2024-02-06T16:26:01Z | https://github.com/langchain-ai/langchain/issues/11470 | 1,929,874,506 | 11,470 |

| ### Issue with current documentation:
The first code example following the Pydantic section, right after "Lets define a class with attributes annotated with types."
results for me in the following pydantic errors using gpt-4:
RuntimeError: no validator found for <class '__main__.Properties'>, see `arbitrary_types_allowed` in Config
The following versions of langchain and pydantic were used:
langchain==0.0.309
pydantic==2.4.2
pydantic_core==2.10.1
### Idea or request for content:
It would be nice to have the code updated so that it works out of the box.
Perhaps a reference to the extraction functions in the 'openai functions' section would be nice. | DOC: pydantic extraction example code not working | https://api.github.com/repos/langchain-ai/langchain/issues/11468/comments | 2 | 2023-10-06T09:27:55Z | 2024-02-10T16:14:42Z | https://github.com/langchain-ai/langchain/issues/11468 | 1,929,774,144 | 11,468 |

### Reproduction
Steps to reproduce:
1. Have a google drive folder with multiple documents with formats like`.mp4`, `.md`, `google docs`, `google sheets` etc.
2. Try using `from langchain.document_loaders import GoogleDriveLoader`, it doesn't work as it only supports google docs, google sheets and pdf files.
```
folder_id = "0ABqitCqK0S_MUk9PVA" # have your own folder id, this is an example
loader = GoogleDriveLoader(
gdrive_api_file=GOOGLE_ACCOUNT_FILE,
folder_id= folder_id,
recursive=True,
# num_results=2, # Maximum number of file to load
)
```
3. Try using `from langchain.document_loaders import UnstructuredFileIOLoader` to load
```
folder_id = "0ABqitCqK0S_MUk9PVA" # have your own folder id, this is an example
loader = GoogleDriveLoader(
service_account_key=GOOGLE_ACCOUNT_FILE,
folder_id=folder_id,
file_loader_cls=UnstructuredFileIOLoader,
file_loader_kwargs={"mode": "elements"},
recursive=True
)
```
4. It throws the following error because `.mp4` files are not supported
`The MIME type is 'video/mp4'. This file type is not currently supported in unstructured.

### Expected behavior
Due to its internal rule of processing audio in [20-minute chunks](https://github.com/langchain-ai/langchain/blob/master/libs/langchain/langchain/document_loaders/parsers/audio.py#L47), `OpenAIWhisperParser` is prone to crashing when transcribing audio with durations that are dangerously close to this limit. Given that OpenAI already has a very low audio length threshold of 0.1 seconds, a simple bypass could effectively resolve this issue.
```python
# https://github.com/langchain-ai/langchain/blob/master/libs/langchain/langchain/document_loaders/parsers/audio.py#L47
chunk_duration = 20
chunk_duration_ms = chunk_duration * 60 * 1000
chunk_length_threshold = 0.1
# Split the audio into chunk_duration_ms chunks
for split_number, i in enumerate(range(0, len(audio), chunk_duration_ms)):
# Audio chunk
chunk = audio[i : i + chunk_duration_ms]
if chunk.duration_seconds < chunk_length_threshold:
continue

'db = Chroma(persist_directory=persist_db, embedding_function=embeddings, collection_name=collection_name)'
. . . then extracting with . . .
'db.get(include=['documents'])'
3. That string is now: leflunomide **(LEF) ( ≤20 mg/day)**, with a single space newly inserted before the ≤
This matters because it messes up retrieval augmentation with queries like “what doses of leflunomide are appropriate?” using Claude-2 as the llm
### Expected behavior
See description above | Chroma is adding an extra space (very consistently) in front of '≤ ’ characters and it has a real impact. | https://api.github.com/repos/langchain-ai/langchain/issues/11441/comments | 7 | 2023-10-05T16:00:27Z | 2024-02-12T16:12:14Z | https://github.com/langchain-ai/langchain/issues/11441 | 1,928,619,715 | 11,441 |

| Hello there,
I have deployed an OpenLLM on a managed service that is protected by the use of an auth Bearer token:
```bash
curl -X 'POST' \
'https://themodel.url/v1/generate' \
-H "Authorization: Bearer Sh6Kh4[ . . . super long bearer token ]W18UiWuzsz+0r+U"
-H 'accept: application/json' \
-H 'Content-Type: application/json' \
-d '{
"prompt": "What is the difference between a pigeon",
"llm_config": {
"use[ . . . and so on]
}
}'
```
Curl works like a charm.
In LangChain, I try to create my new llm as such:
```python
llm = OpenLLM(server_url="https://themodel.url/v1/generate", temperature=0.2)
```
But I don't know how to include this Bearer token, I even suspect it is impossible...
**Bot seems to confirm this is impossible as of 5 Oct 2023, as seen in https://github.com/langchain-ai/langchain/discussions/11437** ; this issue would then be a feature request.
Thanks!
Cheers,
Colin

### Who can help?
Although PGVector implementation utilizes SQLAlchemy that supports connection pooling features, it gets one connection from the pool, saves it as a class attribute and reuses in all requests.
```python
class PGVector(VectorStore):
# ...
def __init__(
self,
# ...
) -> None:
# ...
self.__post_init__()
def __post_init__(
self,
) -> None:
self._conn = self.connect()
# ...
def create_vector_extension(self) -> None:
try:
with Session(self._conn) as session:
# ...
except Exception as e:
self.logger.exception(e)
def create_tables_if_not_exists(self) -> None:
with self._conn.begin():
Base.metadata.create_all(self._conn)
@contextlib.contextmanager
def _make_session(self) -> Generator[Session, None, None]:
yield Session(self._conn)
# ...
```
This means that:
- Since the same connection is user for handle all requests, they will not be executed in parallel but rather enqueued. In a scenario with a large number of requests, this may not scale well.
- Great pool features like connection recycle and test for liveness can not be used.

### Reproduction
1. Configure Postgres to kill idle sessions after 10 seconds (I'm using the `ankane/pgvector` docker image):
```sql
ALTER SYSTEM SET idle_session_timeout TO '10000';
ALTER SYSTEM SET idle_in_transaction_session_timeout TO '10000';
```
2. Restart the database
3. Confirm the new settings are active
```sql
SHOW ALL;
```
4. Create a sample program that instantiate a `PGVector` class and search by similarity every 30 seconds, sleeping between each iteration
```python
if __name__ == '__main__':
# Logging level
logging.basicConfig(level=logging.DEBUG)
load_dotenv()
# PG Vector
driver = os.environ["PGVECTOR_DRIVER"]
host = os.environ["PGVECTOR_HOST"]
port = os.environ["PGVECTOR_PORT"]
database = os.environ["PGVECTOR_DATABASE"]
user = os.environ["PGVECTOR_USER"]
password = os.environ["PGVECTOR_PASSWORD"]
collection_name = "state_of_the_union_test"
connection_string = f'postgresql+{driver}://{user}:{password}@{host}:{port}/{database}'
embeddings = OpenAIEmbeddings()
loader = TextLoader("./state_of_the_union.txt")
documents = loader.load()
text_splitter = CharacterTextSplitter(chunk_size=1000, chunk_overlap=0)
chunks = text_splitter.split_documents(documents)
db = PGVector.from_documents(
embedding=embeddings,
documents=chunks,
collection_name=collection_name,
connection_string=connection_string,
)
for i in range(100):
try:
print('--> *** Searching by similarity ***')
result = db.similarity_search_with_score("foo")
print('--> *** Documents retrieved successfully ***')
# for doc, score in result:
# print(f'{score}:{doc.page_content}')
except Exception as e:
print('--> *** Fail ***')
print(str(e))
print('--> *** Sleeping ***')
time.sleep(30)
print('\n\n')
```
5. Confirm in the console output that some requests fail because the idle connection was closed

### Expected behavior
- Use pooled connections to make feasible executing requests in parallel.
- Allow fine tuning the connection pool used by PGVector, like configuring the its maximum size, number of seconds to wait before giving up on getting a connection from the pool, and enabling [pessimist](https://docs.sqlalchemy.org/en/20/core/pooling.html#pool-disconnects-pessimistic) (liveness testing connections when borrowing them from the pool) or optimistic (connection recycle time) strategies for disconnection dandling.

| ### System Info
I am using Python 3.11.5 and I run into this issue with `ModuleNotFoundError: No module named 'langchain.document_loaders'` after running `pip install 'langchain[all]'`, which appears to be installing langchain-0.0.39
If I then run `pip uninstall langchain`, followed by `pip install langchain`, it proceeds to install langchain-0.0.308 and suddenly my document loaders work again.
- Why does langchain 0.0.39 have document_loaders broken?
- Why does langchain[all] install a different version of langchain?
### Reproduction
1. Install python 3.11.5 (using pyenv on OSX)
2. Run `pip install `langchain[all]'`
3. Observe langchain version that is installed
4. Run `ipython` and execute `from langchain.document_loaders import WebBaseLoader` to receive the module error.
5. Run `pip uninstall langchain`
6. Run `pip install langchain`
7. Note how an older version of langchain is installed
8. Run `ipython` and execute `from langchain.document_loaders import WebBaseLoader` to see how it's working.
### Expected behavior
`pip install langchain` should install the same underlying version of langchain as the version of langchain that includes all of the various modules. | pip installing 'langchain[all]' installs a newer (broken) version than pip install langchain does | https://api.github.com/repos/langchain-ai/langchain/issues/11426/comments | 1 | 2023-10-05T10:49:12Z | 2023-10-05T11:18:44Z | https://github.com/langchain-ai/langchain/issues/11426 | 1,927,989,312 | 11,426 |

| ### System Info
I am using UnstructuredWordDocumentLoader module to load a .docx file. I already tried several things... but the text data returned is always without the percentages that are several times in the .docx file.
How can I maintain / get this (%) percentage symbol?
Thanks

| ### Issue with current documentation:
In the documentation for some examples like [Weaviate](https://api.python.langchain.com/en/latest/vectorstores/langchain.vectorstores.weaviate.Weaviate.html#langchain.vectorstores.weaviate.Weaviate.delete) and [ElasticsearchVectorStore](https://api.python.langchain.com/en/latest/vectorstores/langchain.vectorstores.elasticsearch.ElasticsearchStore.html#langchain.vectorstores.elasticsearch.ElasticsearchStore.delete), the delete method is described as having the ids parameter as optional.
`delete(ids: Optional[List[str]] = None, **kwargs: Any) → None`
However, the ids parameter is mandatory for those vectorstores, and if it is not provided, a ValueError will be raised with the message "No ids provided to delete." Here is the revised [documentation](https://github.com/langchain-ai/langchain/blob/b9fad28f5e093415d76aeb71b5e555eb87fd2ec2/libs/langchain/langchain/vectorstores/elastic_vector_search.py#L336C5-L348C61) to clarify this:
`
def delete(self, ids: Optional[List[str]] = None, **kwargs: Any) -> None:
"""Delete by vector IDs.
Args:
ids: List of ids to delete.
"""
if ids is None:
raise ValueError("No ids provided to delete.")
# TODO: Check if this can be done in bulk
for id in ids:
self.client.delete(index=self.index_name, id=id)
`
### Idea or request for content:
Please clarify in the documentation
Is it also possible to get bulk delete functionality for some vectorstore (ex. ElasticsearchVectorStore/ Weviate)? | DOC: optional ids issue in delete method in vectorstores | https://api.github.com/repos/langchain-ai/langchain/issues/11414/comments | 1 | 2023-10-04T22:50:28Z | 2024-02-06T16:27:01Z | https://github.com/langchain-ai/langchain/issues/11414 | 1,927,090,102 | 11,414 |

| ### Feature request
I would like to implement a `ListOutputParser` that could transform Markdown list into a string list
### Motivation
It seems that most of the lists generated by LLMs are Markdown lists, so I think this will be useful.
It might also make it easier to handle cases where the generated list doesn't work with the existing `ListOutputParser` (Numered and CommaSeparated).
### Your contribution
Here is the PR: https://github.com/langchain-ai/langchain/pull/11411 | Feature: Markdown list output parser | https://api.github.com/repos/langchain-ai/langchain/issues/11410/comments | 1 | 2023-10-04T21:38:14Z | 2023-10-07T01:57:03Z | https://github.com/langchain-ai/langchain/issues/11410 | 1,927,019,118 | 11,410 |

### Reproduction
Hi,
I've just started learning to code with python, working with LLMs and I'm following the [tutorial for setting](https://python.langchain.com/docs/integrations/document_transformers/docai) up LangChain with Google Document AI and I’m getting this error “InvalidArgument: 400 Request contains an invalid argument.” with this line of code
`docs = list(parser.lazy_parse(blob))`
Here are the things I’ve tried so far:
• Setting up gcloud ADC so I can run this as authroized session, code wouldn’t work otherwise
• Set the permission in the GSC bucket to Storage Admin so I can read/write
• Chatgpt wrote test to see if current credentials are working, it is
• Chatgpt wrote test to see if DocAIParser object is working, it is
I think there’s some issue with the output path for “lazy_parse” but I can’t get it to work. I've looked into the documentation but I can't tell if I'm missing something or not. How do I get this working?

| ### Issue you'd like to raise.
I am using Lang chain version 0.0.307 and I noticed an issue with the similarity_score_threshold. I just upgraded from 0.0.208 or 288 (I forgot).
This is the code I am using to retrieve the documents from pinecone:
```
docsearch = Pinecone.from_existing_index(index, embeddings, text_key="text")
retriever = docsearch.as_retriever(
search_type="similarity_score_threshold",
search_kwargs={
'score_threshold': 0.6
}
)
retriever_docs_result = retriever.get_relevant_documents(query)
```
it used to work fine but after upgrading the langchain version it stopped returning any docs. Upon investigating the code, I've noticed that inside the `_similarity_search_with_relevance_scores` method in `vectorstore.py` , `docs_and_scores` is returning the scores as expected but then this code tries to calculate the relevance score and inverts the values:
`return [(doc, relevance_score_fn(score)) for doc, score in docs_and_scores]`.
I am getting search score values as 0.7 to 0.85 but then the relevancy score inverts it and makes it (1-score) which is around 0.3 to 0.15. The problem is the score_threshold works the opposite way. So if I set score_threshold to 0.6 it wants scores bigger than 0.6 which is impossible because the relevancy score makes it invert (if the relevancy score is smaller it means it is more closer to what we queried).
I am using dot product and I have used the following code as well but it also didn't help:
`
docsearch = Pinecone(index, embeddings, text_key="text", distance_strategy=DistanceStrategy.MAX_INNER_PRODUCT)
retriever = docsearch.as_retriever(
search_type="similarity_score_threshold",
search_kwargs={
'score_threshold': 0.6
}
)
`
Can someone help or I am missing something here ?

Hi, I have implemented the indexing workflow as in https://python.langchain.com/docs/modules/data_connection/indexing making use of Pinecone and sqlite. This runs perfect within a Pycharm dev environment. But after building the app with Pyinstaller, I get the following error: sqlite3.OperationalError: unable to open database file. I think this one is coming from langchain.indexes.index. The error message is very cryptic. Why can't this file be opened? Is it locked? Is it corrupted - no as I can open it with a desktop sql manager app. I tried different locations for storing the sqlite database but makes no difference.
Does anyone has some ideas on how to solve this?

### Who can help?
The `ConversationBufferMemory` returns an empty string instead of an empty list when there's nothing stored, which breaks the expectations of the `MessagesPlaceholder` used within the Conversational REACT agent.
Related: https://github.com/langchain-ai/langchain/issues/7365 (where it was commented that changing the loading logic in `ConversationBufferWindowMemory` could break other things).
A possible solution that seems safer (in light of the subsequent type-checking code) could be to default empty strings to empty lists in the `format_messages` method of the `MessagesPlaceholder`, i.e.:
```
class MessagesPlaceholder(BaseMessagePromptTemplate):
...
def format_messages(self, **kwargs: Any) -> List[BaseMessage]:
value = kwargs[self.variable_name]
if not value: ## <-- ADDED CODE
value = [] ## <-- ADDED CODE
if not isinstance(value, list):
raise ValueError(...)
for v in value:
if not isinstance(v, BaseMessage):
raise ValueError(...)
return value
...
```

### Reproduction
To reproduce the behaviour, make sure you have an OPENAI_API_KEY env var and run the following:
```
# pip install langchain openai
import os
from langchain.memory import ChatMessageHistory, ConversationBufferMemory
from langchain.chat_models import ChatOpenAI
from langchain.agents import initialize_agent
from langchain.tools import BaseTool
conversational_memory = ConversationBufferMemory(
memory_key="chat_history",
chat_memory=ChatMessageHistory()
)
llm = ChatOpenAI(
openai_api_key=os.environ['OPENAI_API_KEY'],
temperature=0,
model_name="gpt-4"
)
class MyTool(BaseTool):
name = "yell_loud"
description = "The tool to yell loud!!!"
def _run(self, query, run_manager=None):
"""Use the tool."""
return 'WAAAAH!'
async def _arun(self, query, run_manager=None):
"""Use the tool asynchronously."""
raise NotImplementedError("no async")
agent = initialize_agent(
agent="chat-conversational-react-description",
tools=[MyTool()],
llm=llm,
max_iterations=5,
verbose=True,
memory=conversational_memory,
early_stopping_method='generate'
)
print(agent.run("Please yell very loud, thank you, and then report the result to me."))
# Will raise:
# ValueError: variable chat_history should be a list of base messages, got
# at location:
# "langchain/prompts/chat.py", line 98, in format_messages
```
### Expected behavior
I would expect the script to not complain when the memory is empty and result in something like the following agent interaction (as I got from the modified `format_messages` tentatively suggested above):
```
$> python agent_script.py
> Entering new AgentExecutor chain...
'''json
{
"action": "yell_loud",
"action_input": "Please yell very loud, thank you"
}
'''
Observation: WAAAAH!
Thought:'''json
{
"action": "Final Answer",
"action_input": "The response to your last comment was a loud yell, as you requested."
}
'''
> Finished chain.
The response to your last comment was a loud yell, as you requested.

Hi, I want to clarify some questions about tool and llm usage.
If an agent is initialized with multiple llm and tools,
1. how does the agent choose which llm or tool to use to answer the prompt?
2. How is llm different from tools? Can you give some examples of each category?
3. Can the agent use multiple tools/llm? If the agent can use multiple tools, what happen if the output generated by such tools/llm conflict with each other? In that case, which result will be returned to user?
for example, in the code beloew (cited from langchain doc), the agent is initialized with both 'llm_chain=llm_chain' (where llm_chain is OpenAI)and 'tools=tools' (where tool is google search engine). Which one is used to generate the result?
```search = GoogleSearchAPIWrapper()
tools = [

| ### System Info
Today, all of a sudden I'm getting a error status code 429 using the Conversation chain. Nothing has changed, expect the day I've run the script. Any ideas?
It works with the normal LLM chain, so it must be to do with the Conversation Chain not working or the memories.
Using Flowise.

| ### Issue you'd like to raise.
Hi! I am trying to create a question answering chatbot with PDFs. There is something different in these documents. I have different articles with their number, example: article 1.2.2.1.3, article 1.2.3.4.5, article 2.3.4.1.3, etc.
When I ask for a specific article, it can't find the answer and return "the article x.x.x.x.x is not in the context". I have tried with some embeddings techniques and vector store, but it does not work.
Any ideas?
PD: The PDF documents are around 450 pages

| ### Issue you'd like to raise.
Yeah, so I've been attempting to load Llama2 and utilize Langchain to create a condensed model for my documents. I managed to accomplish the task successfully, as Llama2 generated the results quite effectively. However, when I tried to speed up the process by referencing Langchain's [LLMChain ](https://api.python.langchain.com/en/latest/chains/langchain.chains.llm.LLMChain.html?highlight=llmchain#langchain.chains.llm.LLMChain)and one of its function -- arun, I kept encountering an error that said "Not Implement Error". It didn't matter which function I tried to use, whether it was acall, arun, or apredict, they all failed.
So here are my codes:
```
# load LLama from local drive
tokenizer=AutoTokenizer.from_pretrained("/content/drive/MyDrive/CoLab/LLama7b")
model=LlamaForCausalLM.from_pretrained("/content/drive/MyDrive/CoLab/LLama7b",quantization_config=quant_config,device_map="auto",)
# define output parameters
prefix_llm=transformers.pipeline(
model=model, tokenizer=tokenizer,
return_full_text=True,
task="text-generation",# temperature=0,
top_p=0.15, top_k=15,
max_new_tokens=1060, repetition_penalty=1.2,
do_sample=True
)
# wrap up with Langchain HuggingfaceLLm class
llm=HuggingFacePipeline(pipeline=prefix_llm, cache=False)
# Combine with LLMChain
prompt: PromptTemplate, input_variables="words"
llm_chain = LLMChain(prompt=prompt, llm=llm)
# calling arun
input: list[str]
llm_chain.run(input[num]) || llm_chain.run(words=input[num]) # run smoothly
llm_chain.arun(input) || llm_chain.arun(words=input) # Raise error NotImplementError
```
```
error comes from langchain/llms/base.py in _agenerate(self, prompts, stop, run_manager, **kwargs)
479 ) -> LLMResult:
480 """Run the LLM on the given prompts."""
--> 481 raise NotImplementedError()
482
483 def _stream(
NotImplementedError:
# in this last function, "run_manager" should be None, "stop" too.
```
As far as I explored, this process will call 10 frames. Start on
```
langchian/chains/base.py -> def acall() to
langchian/chains/base.py -> def agenerate()
then jump to
langchian/chains/llm.py -> def _acall() to
langchian/chains/llm.py -> def agenerate()
in the last it stopped at
langchian/llms/base.py -> def agenerate() to
langchian/llms/base.py -> def agenerate_prompt(),
langchian/llms/base.py -> def agenerate_helper()
langchian/llms/base.py -> def _agenerate()
```
I don't know what "thing" I should implement or Langchian didn't implement. the calling code is 100% refer to the [Langchain example](https://python.langchain.com/docs/modules/chains/how_to/async_chain). I suspect maybe it's because Langchain didn't fully support Llama? Since it runs smoothly on OpenAI API.

### Reproduction
Steps to reproduce:
1. Get a document (or set of documents) that will produce a few hundred chunks
2. Run the sample code provided by Langchain to index those documents into the Azure Search vector store (sample code below)
3. Run steps 1 and 2 on another vector store that supports batch embedding (milvus implementation supports batch embeddings)
4. Analyze the delta between the two vectorization speeds (Azure Search should be noticeably slower)
Sample code:
```python
import openai
import os
from langchain.embeddings import OpenAIEmbeddings
from langchain.vectorstores.azuresearch import AzureSearch
vector_store_address: str = "YOUR_AZURE_SEARCH_ENDPOINT"
vector_store_password: str = "YOUR_AZURE_SEARCH_ADMIN_KEY"
embeddings: OpenAIEmbeddings = OpenAIEmbeddings(deployment=model, chunk_size=1)
index_name: str = "langchain-vector-demo"
vector_store: AzureSearch = AzureSearch(
azure_search_endpoint=vector_store_address,
azure_search_key=vector_store_password,
index_name=index_name,
embedding_function=embeddings.embed_query,
)
from langchain.document_loaders import TextLoader
from langchain.text_splitter import CharacterTextSplitter
loader = TextLoader("../../../state_of_the_union.txt", encoding="utf-8")
documents = loader.load()
text_splitter = CharacterTextSplitter(chunk_size=1000, chunk_overlap=0)
docs = text_splitter.split_documents(documents)
vector_store.add_documents(documents=docs)
```
### Expected behavior
The expected behavior for the Azure search implementation to also support batch embedding if the implementation of the embedding class supports batch embedding. This should result in significant speed improvements when comparing the single embedding approach vs the batch embedding approach. | Azure Cognitive Search vector DB store performs slow embedding as it does not utilize the batch embedding functionality | https://api.github.com/repos/langchain-ai/langchain/issues/11313/comments | 6 | 2023-10-02T21:42:29Z | 2024-02-27T11:12:59Z | https://github.com/langchain-ai/langchain/issues/11313 | 1,922,776,905 | 11,313 |

Hi everyone,
I've encountered an issue while trying to instantiate the ConversationalRetrievalChain in the Langchain library. It seems to be related to the abstract class BaseRetriever and the required method _get_relevant_documents.
Here's my base code:
```
import os
from langchain.vectorstores import FAISS
from langchain.chat_models import ChatOpenAI
from langchain.chains.question_answering import load_qa_chain
from langchain.embeddings.openai import OpenAIEmbeddings
from dotenv import load_dotenv
from langchain.memory import ConversationBufferMemory
from langchain.chains import ConversationalRetrievalChain
# Load environment variables
load_dotenv("info.env")
OPENAI_API_KEY = os.getenv("OPENAI_API_KEY")
# Initialize the FAISS vector database
embeddings = OpenAIEmbeddings(openai_api_key=OPENAI_API_KEY)
index_filenames = ["index1", "index2"]
dbs = {f"category{i+1}": FAISS.load_local(filename, embeddings) for i, filename in enumerate(index_filenames)}
# Load chat model and question answering chain
llm = ChatOpenAI(model_name="gpt-3.5-turbo", temperature=0, openai_api_key=OPENAI_API_KEY)
chain = load_qa_chain(llm, chain_type="map_reduce")
# Initialize conversation memory
memory = ConversationBufferMemory(memory_key="chat_history", return_messages=True)
# Set the role of the AI
role = "Assistant"
# Write the role of the AI
memory.save_context({"input": f"AI: As an {role}, I can help you with your questions based on the retrievers and my own data."}, {"output": ""})
# Initialize the ConversationalRetrievalChain with memory and custom retrievers
qa = ConversationalRetrievalChain.from_llm(llm, retriever=dbs, memory=memory)
# Pass in chat history using the memory
while True:
user_input = input("User: ")
# Add user input to the conversation history
memory.save_context({"input": f"User: {user_input}"}, {"output": ""})
# Check if the user wants to exit
if user_input == "!exit":
break
# Run the chain on the user's query
response = qa.run(user_input)
# Print the response with a one-line space and role indication
print("\n" + f"{role}:\n{response}" + "\n")
```
And here's the error message I received:
```
pydantic.v1.error_wrappers.ValidationError: 1 validation error for ConversationalRetrievalChain
retriever
Can't instantiate abstract class BaseRetriever with abstract method _get_relevant_documents (type=type_error)
```
It appears that the retriever I provided doesn't fully implement the required methods. Could someone provide guidance on how to properly implement a retriever for ConversationalRetrievalChain and help update the code based on that?
Any help would be greatly appreciated. Thank you!

| ### Feature request
we are using your VLLMOpenAI class in a project to connect to our vLLM. we however don't use openAI, and found kind of weird that you have this implemented, but naming suggests it is specifically for openAI only. You could generalise this class so that it can be used with any kind of vLLM (which it already does). So basically just some refactoring might be the whole thing.
### Motivation
We are using this VLLMOpenAI class with other open source models. Kind of misleading and unintuitive to say we use the VLLMOpenAI class. We wish ourselves a custom class for open source models or any other kind of vLLM deployment.
### Your contribution
No time capacity :( So other than my genuine enthusiasm on your project and the whole documenting of the feature I can't really offer much more... | VLLMOpenAI class should be generalised | https://api.github.com/repos/langchain-ai/langchain/issues/11291/comments | 5 | 2023-10-02T14:25:10Z | 2024-02-09T16:19:48Z | https://github.com/langchain-ai/langchain/issues/11291 | 1,922,030,381 | 11,291 |

| ### Feature request
Hi, I'd like to request the chain type of Chain-of-Verification (CoVe).
### Motivation
I see that there's already a `LLMCheckerChain` and a `SmartLLMChain` which use related techniques, but implementing the below four-step process as described in https://arxiv.org/abs/2309.11495 would, I think, still be a very popular feature.
**Chain-of-Verification steps:**
1. drafts an initial response
2. plans verification questions to fact-check its draft
3. answers those questions independently so the answers are not biased by other responses
4. generates its final verified response

### Reproduction
Steps to reproduce:
Installing langchain
Importing langchain.chat_modules
### Expected behavior
Module loads successfully | ModuleNotFoundError: No module named 'langchain.chat_models' | https://api.github.com/repos/langchain-ai/langchain/issues/11277/comments | 4 | 2023-10-02T06:45:42Z | 2024-02-21T16:08:24Z | https://github.com/langchain-ai/langchain/issues/11277 | 1,921,339,371 | 11,277 |

| ### Feature request
I want simple methods to use on the various memory classes to enable easy serialization and de serialization of the current state of the convo, crucially including system messages as json dictionaries.
If this is currently already included, I cannot for the life of me find it anywhere in the documentation or the source code.
In particular there doesn't seem to be a way to add system messages directly to the memory.
Heres some pseudo code outlining what this would look like
```python
serialized_memory = memory_instance.serialize_to_json()
new_memory = MemoryClass()
new_memory.load_from_json(serialized_memory)
```
In the new memory, the entire contents of the history(at least what has not been pruned) would be included. Including any system messages, which with the summary variants would include the convo summaries.
### Motivation
The absence of easy serialization and deserialization methods makes it difficult to save and load conversations in JSON files or other formats. Working with dictionaries is straightforward, and they can be easily converted into various data storage formats.
### Your contribution
Possibly. I just started messing around with this module today, and I am relatively new to Python. I will be doing my best to learn more about how this library works so I can add this feature.
With some more research and experimentation this could be something I could do. | Simple Serialization and Deserialization of Memory classes to and from dictionaries w/ System Messages included | https://api.github.com/repos/langchain-ai/langchain/issues/11275/comments | 8 | 2023-10-02T04:50:53Z | 2024-02-15T16:09:05Z | https://github.com/langchain-ai/langchain/issues/11275 | 1,921,243,571 | 11,275 |

| ### System Info
I'm trying to use langchain with cache using gptcache, using pydantic models
(prior to this message I'm building prompt of mixed human and system messages)
```
chain = create_structured_output_chain(Job, llm, prompt, verbose=False)
res = chain.run({'job': job})
```
when not using cache everything seems to work but when getting from cache I'm seeing this error:
```
File "/Users/orlevy/Projects/tfg/llm-service/venv/lib/python3.9/site-packages/langchain/schema/output.py", line 62, in set_text
values["text"] = values["message"].content
KeyError: 'message'
```
When I digged a little further it seems like this code, is not generating the same response (we are losing function call response) :
<img width="661" alt="image" src="https://github.com/langchain-ai/langchain/assets/21291210/cfeccb45-4806-4f85-a01c-67b42a882c8d">
modified code a bit(not sure if this is actually a good idea) but this one seems to work for chat:
```
res = get(prompt, cache_obj=_gptcache)
if res:
return [
ChatGeneration(
message=AIMessage(content='',
additional_kwargs=generation_dict['message']['additional_kwargs']
),
generation_info=dict(finish_reason=generation_dict.get("finish_reason")),
) for generation_dict in json.loads(res)
]
```
would really appreciate
your help with this

### Bug Detail
Playing around with a recursive function to decrement value `k` and ran into an issue whereby `self` is overwritten and bound to instance of `openai.error.InvalidRequestError` when the exception is caught. Note in the code below, the `AttributeError` exception is thrown when `self.save()` is executed upon a successful `run()` or `try` where `openai.error.InvalidRequestError` is not thrown.

| ### Feature request
Is it possible to integrate any language model (LM) trained on source code or opensource codebases on various programming languages e.g. :
- [StarCoder](https://github.com/bigcode-project/starcoder)
- [replit/replit-code-v1-3b](https://huggingface.co/replit/replit-code-v1-3b)
- [Bloom](https://bigscience.huggingface.co/blog/bloom)
- etc...
as an [LLM Model](https://python.langchain.com/en/latest/modules/models.html) or an [Agent](https://python.langchain.com/en/latest/modules/agents.html) with [LangChain](https://github.com/hwchase17/langchain), and [chain](https://python.langchain.com/en/latest/modules/chains.html) it in a complex usecase?
It would be really cool if, during a general query, the LangChain system has the capability to understand code context (possibly when chained to a vector DB or any data source that contains code or a full code repo), _kind of like chatting with your codebase_!
Any help / hints on the same would be appreciated!
### Motivation
Initially inspired by this [Issue #173](https://github.com/nomic-ai/gpt4all/issues/173)
Raised a similar Issue long back with StarCoder [Issue #53](https://github.com/bigcode-project/starcoder/issues/53)

| ### Feature request
We all want to have our clients to interact with the database using LLM, langchain with create_sql_agent, are great, the only problem I see, there is no way to limit user access to the database and fence him to his data.
For example we have table called AI_Product with many columns and one of them is storeid, for normal user, he should have limited access to this table, I also don't trust the AI to limit that, there should be a way to programmatically do that.
So let's look at AI_Product
```
id, name, price, store_id
1, water, 2, 10001
2, pepsi, 4, 10001
3, cokezero , 5, 10002
```
For the above table, the user only have rights to access storeid= 10001, for security and true data we need a way to limit what this user can see.
One solution could be is to allow include_tables to have sql
`include_tables = ['AI_Product']
`
to
`include_tables = ['(select * from AI_Product where store_id = '10001') AI_Product']
`
The other one, is allow the SQL query to come back before execution and allow me to modify it
So if I asked , "How many products do we have?"
```
agent: sql:"select count(*) from AI_Product"
Then we can modify the sql to
protected_sql = sql.replace("AI_Product", "(select * from AI_Product where store_id = '10001') AI_Product")
#sql = "select count(*) from (select * from AI_Product where store_id = '10001') AI_Product"
agent.run (protected_sql)
```

| ### Issue you'd like to raise.
while RAG we create a db and then we ask a query to the db in this way,
`index = VectorstoreIndexCreator(
vectorstore_cls=DocArrayInMemorySearch
).from_loaders([loader])`
`index.query(llm=chat, question=query)`
we get some response.
Now lets say wanted to create dataset with the generations ive got from gpt to fintune llama2 llm.
the main problem comes here, now how to know what is the reference we got from the index search as it is totaly abstracted!!
i need the exact querry that gone into llm(gpt) in this process.
Or else can i have any other meathod that solves my problem(tried similarity search and fed reference+query manualy the quality of the output droped so i need index search it self.

| ### Feature request
[LanguageParser](https://github.com/langchain-ai/langchain/blob/e9b51513e9bab738c741a348ffbf0f36ce19faf6/libs/langchain/langchain/document_loaders/parsers/language/language_parser.py#L21C7-L21C21) is a parser for Document Loaders that, given source code, splits each top-level function or class into separate documents. As stated in its documentation:
> This approach can potentially improve the accuracy of QA models over source code.
>
> Currently, the supported languages for code parsing are Python and JavaScript.
We would like to add support for additional languages, such as C, C++, Rust, Ruby, Perl, and so on.
### Motivation
There is an [open request](https://github.com/langchain-ai/langchain/issues/10996) for "CPP" (presumably C++) support. By integrating a generic parsing library (such as [tree-sitter](https://github.com/tree-sitter/py-tree-sitter#py-tree-sitter)), we could make LanguageParser work with many more languages, and thus be more generally useful.

How do you stream a langchain response from Flask to React?
I am having issues with it. I successfully implemented it with Azure OpenAI API only but langchain doesn't give me the right implementation.

| ### System Info
Following the steps of indexing from [ https://python.langchain.com/docs/modules/data_connection/indexing ](url) you'll find the following error "redis.exceptions.ResponseError: my_docs: no such index".
You'll get this exception while using redis as retriever:

### Reproduction
The error is here:
If you look for the index you'll get (empty list or set).
This line makes impossible to save in the wanted format, and there's another thing: The index is not created for some reason.
I'll try to fix, but I'm not sure if it's possible for me at the moment, so I'm reporting this, I hope it helps.

### Reproduction
As of Bedrock GA today, I get this error:
"/var/task/langchain/llms/bedrock.py", line 237, in _prepare_input_and_invoke raise ValueError(f"Error raised by bedrock service: {e}") ValueError: Error raised by bedrock service: An error occurred (ValidationException) when calling the InvokeModel operation: The requested operation is not recognized by the service.

It should invoke the model.

### Reproduction
Steps to reproduce:
1. Initialize ChatAnthropic model, with keyword "anthropic_api_key", as documented: https://api.python.langchain.com/en/latest/chat_models/langchain.chat_models.anthropic.ChatAnthropic.html#langchain.chat_models.anthropic.ChatAnthropic
2. Call chat model via __call__ method, e.g.:
"""
chat = ChatAnthropic(..., anthropic_api_key=os.environ["ANTHROPIC_API_KEY"])
messages = [....]
response = chat(messages)
"""
### Expected behavior
A normal response for a chat model is expected, but instead we get:

| ### Feature request
Bedrock added support for Cohere models and the Bedrock llm code must be updated with the right prompt formatting.
The prompt must be passed as `"prompt"` field and not as the code below does as `"input"`
```
{
"modelId": "cohere.command-text-v14",
"contentType": "application/json",
"accept": "*/*",
"body": {
"prompt": "Write a LinkedIn post about starting a career in tech:",
"max_tokens": 100,
"temperature": 0.8,
"return_likelihood": "GENERATION"
}
}
