] | ### Issue you'd like to raise.
Hi, I am trying to stream the response from the llm back to the client by using a callback with a custom StreamHandler, but the on_llm_new_token also includes the output from the rephrase_question step. while the final response does not include the rephrased answer. I don't want the rephrased question to be present in the response that is streaming.
the StreamHandler class is given below
`class StreamHandler(BaseCallbackHandler):
def __init__(self):
self.text = ""
def on_llm_new_token(self, token: str, **kwargs):
old_text = self.text
self.text += token
# Calculate the new content since the last emission
new_content = self.text[len(old_text) :]
socketio.emit("update_response", {"response": new_content})`
The qa-chain is defined as below:
qa_chain = ConversationalRetrievalChain.from_llm(
llm=chat,
retriever=MyVectorStoreRetriever(
vectorstore=vectordb,
search_type="similarity_score_threshold",
search_kwargs={"score_threshold": SIMILARITY_THRESHOLD, "k": 1},
),
return_source_documents=True,
rephrase_question=False)
response = qa_chain(
{
"question": user_input,
"chat_history":chat_history,
},callbacks=[stream_handler] )
### Suggestion:

] | ### Issue you'd like to raise.
Recently, langchain released the google gemini independent package to connect the google gemini LLM capabilities.
This is also the first independent package released by langchain, which is a very big progress and change.
But I noticed that the name of this package is langchain-google-genai, which may not be very systematic.
Perhaps, we can use python's namespace feature to manage all langchain-related packages.
Documentation about namespace package:
- https://packaging.python.org/guides/packaging-namespace-packages/
- https://www.python.org/dev/peps/pep-0420/
### Suggestion:
Use the namespace capability to manage and publish all independent packages of langchain. The specific directory structure is as follows：
docs: https://packaging.python.org/en/latest/guides/packaging-namespace-packages/
```
pyproject.toml # AND/OR setup.py, setup.cfg
src/
langchain/ # namespace package
# No __init__.py here.
google-genai/
# Regular import packages have an __init__.py.
__init__.py
module.py
```
and then, you can use like:
```python
import langchain.google-genai
from langchain import google-genai
# ... code
``` | Issue: Use python namespace capabilities to manage standalone packages | https://api.github.com/repos/langchain-ai/langchain/issues/14694/comments | 1 | 2023-12-14T03:49:26Z | 2024-03-21T16:06:07Z | https://github.com/langchain-ai/langchain/issues/14694 | 2,040,852,615 | 14,694 |

With Gemini Pro going GA today (Dec. 13th).
When can users of LangChain expect an update to use the new LLM?

The agent will use the alias names instead of the field name. i.e (workspaceId, dueDate) instead of (workspace_id, due_date)

"{'name': 'Update code', 'workspaceId': 'xxxxxyyyyyzzzzz', 'dueDate': '2023-12-14T00:00:00'}"
```
When the agent calls `_parse_input` function from [langchian_core/tools.py and reaches line 247](https://github.com/langchain-ai/langchain/blob/14bfc5f9f477fcffff3f9aa564a864c5d5cd5300/libs/core/langchain_core/tools.py#L247) the results are filtered out because the results have the field names and the tool_input has the alias names which do not match.

I am attempting to call an instance of ConversationalRetrieverChain with a list of dictionary objects that I've pre-processed with a similarity search and cohere reranker. I've created an extension of BaseRetriever in order to pass my list of dictionary objects to the "retriever=" parameter. However when my extended class instantiates, I get an error saying "seai_retriever object has no field "documents". My code is below. What am I doing wrong?
```

from typing import List
class seai_retriever(BaseRetriever):
def __init__(self, documents):
self.documents = documents
def retrieve(self, query, top_n=10):
retrieved_docs = [doc for doc in self.documents if query.lower() in doc['content'].lower()]
retrieved_docs = sorted(retrieved_docs, key=lambda x: x['content'].find(query), reverse=True)[:top_n]

from langchain.text_splitter import TokenTextSplitter
token_splitter_model_name = "gpt-3.5-turbo"
SPLIT_CHUNK_SIZE = 1024
CHUNK_OVERLAP = 256
text_splitter = TokenTextSplitter.from_tiktoken_encoder(model_name=token_splitter_model_name, chunk_size=SPLIT_CHUNK_SIZE , chunk_overlap = CHUNK_OVERLAP)
blog_content= ' your text here'
blog_splits=text_splitter.split_text(blog_content)
```
### Expected behavior
The ways this token text splitter works , isn't how it is intended to work .
For Example :-
When specified chunk_size = 1024 and overlap = 256 with input text tokens = 991 , it made two chunks ;
first = token[0 : 991]
second = token[768 : 991]
but logically it should work this ways .
If input text token >1024 , there should be two chunks .
first = token[0 : 1024]
second = token[768 : ]
and so on ..............
If input text token <=1024 , there should be one chunk only .
first = token[ 0 : ]

The 1st code is to load PDF documents and use ParentDocumentRetriever to add_documents() and save vectorstore to local disk.
The 2nd code is to load vectorstore and call ParentDocumentRetriever.get_relevant_documents
The problem is, the ParentDocumentRetriever.get_relevant_documents() got empty result.
Any idea??
What is the inMemoryStore for??
Here are the two codes:
### the 1st code: LoadDocumentsAndSaveVectorstore.py
```
loader = DirectoryLoader('data/',

docs = loader.load()
store = InMemoryStore()

retriever.add_documents(docs, ids=None)
vectorstore.save_local("ppstore")
print("save data to ppstore")
```
The 1st code works fine.
The 2nd file is to load the vectorstore and query.
The strange thing is, the **retriever1.get_relevant_documents(query)** got empty result.
### the 2nd code: load vectorstore and use retriever to get relevant_documents
```
print("load ppstore")

Issue 1:
I am working on the summarization using the stuff and map-reduce of the Langchain. I have integrated it with the AWS Bedrock's anthropic llm which has a token limit of 100000. It is working fine but when the pdf with 40000 tokens is passed, the bedrock is throwing an error:
i) with VPN connected:
An error occurred: Error raised by bedrock service: Could not connect to the endpoint URL: "https://bedrock-runtime.us-east-1.amazonaws.com/model/anthropic.claude-v2/invoke".
ii) without VPN connected:
An error occurred: Error raised by bedrock service: An error occurred (ExpiredTokenException) when calling the InvokeModel operation: The security token included in the request is expired
Any reason why this is happening? thanks in advance!
Issue 2:
2) map-reduce takes a lot of time to produce the summary for the 40000+ tokens documents when the anthropic threshold is reduced to 40000. Sometimes it is taking a lot of time but erroring out. Any help is appreciated. Thanks in advance!

Hello, after forking and cloning the repo on my machine, I tried to open it using docker and specifically in VS Code with the option to "Reopen in Container". While building, the final command of [dev.Dockerfile](https://github.com/langchain-ai/langchain/blob/ca7da8f7ef9bc7a613ff07279c4603cad5fd175a/libs/langchain/dev.Dockerfile#L44) resulted in the following error:
```logs
#0 1.241 Directory ../core does not exist
```
After investigating, I found out that the issue lies in [pyproject.toml](https://github.com/langchain-ai/langchain/blob/ca7da8f7ef9bc7a613ff07279c4603cad5fd175a/libs/langchain/pyproject.toml) which is using relative paths like `../core` and `../community` in some occasions. Additionally, even after replacing `../` with `libs/` (which I am not sure if it breaks something else), the actual `core` and `community` directories are never copied over in [dev.Dockerfile](https://github.com/langchain-ai/langchain/blob/ca7da8f7ef9bc7a613ff07279c4603cad5fd175a/libs/langchain/dev.Dockerfile). These should also be copied in the created docker container, similarly to [line 41](https://github.com/langchain-ai/langchain/blob/ca7da8f7ef9bc7a613ff07279c4603cad5fd175a/libs/langchain/dev.Dockerfile#L41).
After making these two changes, the container was successfully built. I'll check out whether the change of paths in pyproject.toml is affecting any other files, and if not I will create a PR for this.

Add first-class support for Vertex AI Endpoints in Langchain. This would involve providing a similar interface to the existing SageMakerEndpoint class, allowing users to easily connect to and interact with Vertex AI Endpoints.
### Motivation
Although VertexAIModelGarden already exist, there may be instances where users require custom models with unique input and output formats. To address this need, a more versatile class could be developed, upon which VertexAIModelGarden could be built. This would allow for seamless integration of custom models without compromising the functionality of the existing Model Garden class.

### Reproduction
Use the QA With Sources chain with the default prompt. If the chain type is `stuff` or `map_reduce` the default prompts used are [this](https://github.com/langchain-ai/langchain/blob/master/libs/langchain/langchain/chains/qa_with_sources/stuff_prompt.py) and [this](https://github.com/langchain-ai/langchain/blob/master/libs/langchain/langchain/chains/qa_with_sources/map_reduce_prompt.py) respectively. These files are massive, and easily adds a 1000+ tokens to every request. In models like PALM2, there's barely any tokens left for other questions.
### Expected behavior
These prompts should be much more short, even if as a sample input. | QaWithSources default prompt is massive | https://api.github.com/repos/langchain-ai/langchain/issues/14596/comments | 4 | 2023-12-12T13:40:37Z | 2024-03-20T16:06:19Z | https://github.com/langchain-ai/langchain/issues/14596 | 2,037,780,695 | 14,596 |

"hwchase17",

] | ### Feature request
As of the current implementation of the QA with sources chain, if `return_source_documents` is set to `True`, [all the sources](https://github.com/langchain-ai/langchain/blob/76905aa043e3e604b5b34faf5e91d0aedb5ed6dd/libs/langchain/langchain/chains/qa_with_sources/base.py#L165) that are retrieved from the vector DB are returned. The `sources` field returns a list of file names that were used by the LLM. I propose we could do something like this
1. Assign each `Document` a unique UUID as the `source` before passing it to the LLM.
2. Once the LLM returns the relevant sources, we can backmap this to the actual `Document`s that were used by the LLM as opposed to getting just the filename.
### Motivation
This information seems vastly more useful than the entire response from the vector DB. For our current use cases, we've ended up overriding these functions to add this functionality.
### Your contribution
I can raise a PR adding this if this is something that you'd find useful as well.
An additional issue to report, the `_split_sources` [function](https://github.com/langchain-ai/langchain/blob/76905aa043e3e604b5b34faf5e91d0aedb5ed6dd/libs/langchain/langchain/chains/qa_with_sources/base.py#L124) splits at the first instance of `SOURCE` which seems to be a bit problematic. I can fix this to split at the last occurence. | Sources returned in QaWithSources can be optimised | https://api.github.com/repos/langchain-ai/langchain/issues/14595/comments | 1 | 2023-12-12T13:30:30Z | 2024-03-19T16:06:24Z | https://github.com/langchain-ai/langchain/issues/14595 | 2,037,760,278 | 14,595 |

```
Result: ` < """"""""""""""""""""""/"`
Requesting you to look into it.
Please let me know in case you need more information.
Thank you.
I have tried the same model file with **[llama-cpp-python](https://github.com/abetlen/llama-cpp-python)** package and it works as expected.
Please find below the code that I have tried:
```
import json
import time
from llama_cpp import Llama
n_gpu_layers = 1 # Change this value based on your model and your GPU VRAM pool.
n_batch = 512
llm = Llama(model_path="../models/deepcoder-gguf/deepseek-coder-6.7b-instruct.Q5_K_M.gguf" , chat_format="llama-2", n_gpu_layers=n_gpu_layers,n_batch=n_batch)
start_time = time.time()
pp = llm.create_chat_completion(
messages = [
{"role": "system", "content": "You are an python language assistant."},
{
"role": "user",
"content": "Write quick sort ."
}
])
end_time = time.time()
print("execution time:", {end_time - start_time})
print(pp["choices"][0]["message"]["content"])
```
Output :
```
## Quick Sort Algorithm in Python
Here is a simple implementation of the quicksort algorithm in Python:
```python
def partition(arr, low, high):
i = (low-1) # index of smaller element
pivot = arr[high] # pivot
for j in range(low , high):
if arr[j] <= pivot:
i += 1
arr[i],arr[j] = arr[j],arr[i]
arr[i+1],arr[high] = arr[high],arr[i+1]
return (i+1)
def quickSort(arr, low, high):
if low < high:
pi = partition(arr,low,high)
quickSort(arr, low, pi-1)
quickSort(arr, pi+1, high)
# Test the code
n = int(input("Enter number of elements in array: "))
print("Enter elements: ")
arr = [int(input()) for _ in range(n)]
quickSort(arr,0,n-1)
print ("Sorted array is:")
for i in range(n):
print("%d" %arr[i]),
This code first defines a helper function `partition()` that takes an array and two indices. It then rearranges the elements of the array so that all numbers less than or equal to the pivot are on its left, while all numbers greater than the pivot are on its right. The `quickSort()` function is then defined which recursively applies this partitioning process until the entire array is sorted.
The user can input their own list of integers and the program will output a sorted version of that list.
[/code]
Conclusion
In conclusion, Python provides several built-in functions for sorting lists such as `sort()` or `sorted()` but it's also possible to implement quick sort algorithm from scratch using custom function. This can be useful in situations where you need more control over the sorting process or when dealing with complex data structures.
```
### Expected behavior
It should inference the model just like the native [llama-cpp-python](https://github.com/abetlen/llama-cpp-python) package. | Not able to inference deepseek-coder-6.7b-instruct.Q5_K_M.gguf | https://api.github.com/repos/langchain-ai/langchain/issues/14593/comments | 6 | 2023-12-12T11:20:20Z | 2024-05-25T13:36:24Z | https://github.com/langchain-ai/langchain/issues/14593 | 2,037,539,816 | 14,593 |

### Reproduction
When you use caching with LangChain, it does not distinguish different LLM models. For example, the response for LLama2 was used for a prompt for Claude 2.
```
def ask_name(model_id):
question = 'what is your name?'
bedrock = Bedrock(model_id=model_id, model_kwargs={'temperature': 0.1})
print('me: ' + question)
t0 = datetime.datetime.now()
print(f'{bedrock.model_id}: ' + bedrock(question).strip())
print('({:.2f} sec)'.format((datetime.datetime.now() - t0).total_seconds()))
print()
model_ids = ['meta.llama2-70b-chat-v1','anthropic.claude-v2',]
for model_id in model_ids:
ask_name(model_id)
ask_name(model_id)
```
==>
```
me: what is your name?
meta.llama2-70b-chat-v1: Answer: My name is LLaMA, I'm a large language model trained by a team of researcher at Meta AI.
(2.24 sec)
me: what is your name?
meta.llama2-70b-chat-v1: Answer: My name is LLaMA, I'm a large language model trained by a team of researcher at Meta AI.
(0.00 sec)
me: what is your name?
anthropic.claude-v2: Answer: My name is LLaMA, I'm a large language model trained by a team of researcher at Meta AI.
(0.00 sec)
```
This is because of https://github.com/langchain-ai/langchain/blob/db6bf8b022c17353b46f97ab3b9f44ff9e88a488/libs/langchain/langchain/llms/bedrock.py#L235
```
@property
def _identifying_params(self) -> Mapping[str, Any]:
"""Get the identifying parameters."""
_model_kwargs = self.model_kwargs or {}
return {
**{"model_kwargs": _model_kwargs},
}
```
My current workaround is subclassing the `Bedrock` class:
```
class MyBedrock(Bedrock):
@property
def _identifying_params(self) -> Mapping[str, Any]:
"""Get the identifying parameters."""
return {
'model_id': self.model_id,
**BedrockBase._identifying_params.__get__(self)
}
```
This seems working.

```
### Expected behavior
The output line `received LLM response: generations=[[Generation(text='answer1')]] llm_output=None run=None` should also appear with `answer2`, because that one is also generated while running the chain that was configured to use the `CustomCallbackHandler`.
The callbacks should also be used in the chain that is created inside the OutputFixingParser. In my opinion, the chain doing the retry, should have the overall chain as a parent in the callback methods (`on_chain_start()` an so on). | OutputFixingParser should use callbacks | https://api.github.com/repos/langchain-ai/langchain/issues/14588/comments | 1 | 2023-12-12T09:35:53Z | 2024-03-19T16:06:02Z | https://github.com/langchain-ai/langchain/issues/14588 | 2,037,349,229 | 14,588 |

Currently, SemanticSimilarityExampleSelector only passes `k` as a parameter to vectorstore [see here](https://github.com/langchain-ai/langchain/blob/76905aa043e3e604b5b34faf5e91d0aedb5ed6dd/libs/core/langchain_core/example_selectors/semantic_similarity.py#L55C10-L55C10). vectorstore, depending on the implementation can take multiple other arguments. most notably, `filters` can be passed down [see here](https://github.com/langchain-ai/langchain/blob/76905aa043e3e604b5b34faf5e91d0aedb5ed6dd/libs/community/langchain_community/vectorstores/faiss.py#L505C13-L507C38)
### Motivation
Having the ability to filter down examples (on top of similarity search) would be very helpful in controlling the examples that are added to the prompt. This feature provides significant more control over examples selection.
### Your contribution
It is very easy to update this. add a new attribute `vectorstore_kwargs` to the class
class SemanticSimilarityExampleSelector(BaseExampleSelector, BaseModel):
"""Example selector that selects examples based on SemanticSimilarity."""
vectorstore: VectorStore
"""VectorStore than contains information about examples."""
k: int = 4
"""Number of examples to select."""
example_keys: Optional[List[str]] = None
"""Optional keys to filter examples to."""
input_keys: Optional[List[str]] = None
"""Optional keys to filter input to. If provided, the search is based on
the input variables instead of all variables."""
vectorstore_kwargs: Optional[Dict[str, Any]] = None
"""additional arguments passed to vectorstore for similarity search."""
and then update the `select_examples` function with
`example_docs = self.vectorstore.similarity_search(query, k=self.k, **self.vectorstore_kwargs)` | passing down vectorstore additional argument in SemanticSimilarityExampleSelector | https://api.github.com/repos/langchain-ai/langchain/issues/14583/comments | 1 | 2023-12-12T07:18:55Z | 2024-03-19T16:05:52Z | https://github.com/langchain-ai/langchain/issues/14583 | 2,037,136,239 | 14,583 |

Hi,
I have this issue when working with more than 1 table using the Llama2 model. Let's say table 1 has values A, B, C, and table 2 has values X, Y, Z. When I run the query, it often gives me an error that it creates the query but assumes that table 1 has values X, Y, Z, and it mixes them up. Any suggestions on how to avoid this? I'm trying to solve it with prompts, but the model seems to ignore instructions in these cases.

from langchain.agents.agent_toolkits import PowerBIToolkit
from langchain.utilities.powerbi import PowerBIDataset
from azure.identity import ClientSecretCredential
from azure.core.credentials import TokenCredential
# Create an instance of the language model (llm)
toolkit = PowerBIToolkit(
powerbi=PowerBIDataset(
dataset_id="",
table_names=['WinShareTable'],
credential=ClientSecretCredential(
client_id=",
client_secret='',
tenant_id=""
)
),
llm=llm
)
Either getting field "credential" not yet prepared so type is still a ForwardRef, you might need to call PowerBIDataset.update_forward_refs() error or
Tokencredentials error
### Expected behavior
Should allow to connect to PowerBi datasets | impossible to connect to PowerBI Datasets even after providing all the information | https://api.github.com/repos/langchain-ai/langchain/issues/14538/comments | 1 | 2023-12-11T14:07:35Z | 2024-03-18T16:08:54Z | https://github.com/langchain-ai/langchain/issues/14538 | 2,035,763,317 | 14,538 |

Page: https://python.langchain.com/docs/modules/memory/
In dark mode, there is very little contrast between inputs and outputs. Especially for pages imported from Jupyter notebooks, it can be really confusing figuring out which code blocks are safe to test in a `.py` function and which code blocks are intended for use in Jupyter.
Adding in explicit contrast or labeling between input and output blocks would be helpful.
### Idea or request for content:
_No response_ | DOC: Please add stronger contrast or labeling between notebook input and output blocks | https://api.github.com/repos/langchain-ai/langchain/issues/14532/comments | 2 | 2023-12-11T12:20:45Z | 2024-04-01T16:05:54Z | https://github.com/langchain-ai/langchain/issues/14532 | 2,035,556,970 | 14,532 |

] | ### Feature request
Weaviate has released a beta version of their [python client v4](https://weaviate.io/developers/weaviate/client-libraries/python) which seems to be more robust compared to v3. It follows a different structure but allows for more versatility and better error handling when it comes to queries. I think it would be great to add support in langchain for the new client.
### Motivation
I was using the v3 client (without langchain) to batch import data into Weaviate. It worked, but it was slower than I expected and also resulted in errors that I was not able to manage easily. The new v4 client supports their new [gRPC API](https://weaviate.io/developers/weaviate/api/grpc) which outperforms the traditional REST API that v3 is using.
### Your contribution
I will start creating some custom functions using Weaviate's new client to test its reliability. If I don't encounter any serious errors, I'll try to find the time and create a PR to add support for it in langchain. I think that support for both v3 and v4 should exist, at least until v4 becomes stable. | Support Weaviate client v4 | https://api.github.com/repos/langchain-ai/langchain/issues/14531/comments | 1 | 2023-12-11T12:15:23Z | 2024-03-12T13:14:58Z | https://github.com/langchain-ai/langchain/issues/14531 | 2,035,547,273 | 14,531 |

### Reproduction
I'm looking to run a simple RAG using Qdrant pre instantiated with data (something like the [link from the docs](https://colab.research.google.com/drive/19RxxkZdnq_YqBH5kBV10Rt0Rax-kminD?usp=sharing#scrollTo=fvCHMT73SmKi)) but its giving me the error in the title.
I'm posting it here since the error seems to be on langchain side. not qdrant side.
Ive tried various ways of using langchain to connect to qdrant but it always ends up with this error.
This happens even if i use the deprecated VectorDBQA or RetrievalQA
```
from qdrant_client import QdrantClient
from langchain.chat_models import AzureChatOpenAI
from langchain.embeddings import HuggingFaceEmbeddings
from langchain.vectorstores import Qdrant
QDRANT_ENDPOINT = "localhost"
MODEL_TO_USE = 'BAAI/bge-base-en-v1.5'
collection_name = "collection"
client = QdrantClient(QDRANT_ENDPOINT, port=6333, timeout=120)
embeddings = HuggingFaceEmbeddings(model_name=MODEL_TO_USE)
qdrant = Qdrant(client, collection_name, embeddings)
qdrant.similarity_search("middle east")
```
gives
```
>>> qdrant.similarity_search("middle east")

This function breaks the pattern of how the `embedding_function` is referenced by just calling it `embedding`.
Small issue but definitely makes it a bit confusing to navigate without diving into the code/docs.

### Reproduction
I am using Qdrant on docker with information preloaded. However im unable to get it to search
```
MODEL_TO_USE = 'all-mpnet-base-v2'
client = QdrantClient(QDRANT_ENDPOINT, port=6333, timeout=120)
embeddings = HuggingFaceEmbeddings(model_name=MODEL_TO_USE)
qdrant = Qdrant(client, collection_name, embeddings)
conversation_chain = ConversationalRetrievalChain.from_llm(
llm=llm,
retriever=qdrant.as_retriever(search_kwargs={'k': 5}),
get_chat_history=lambda h : h,
memory=memory
)
# im using a streamlit frontend
import streamlit as st
st.session_state.conversation = conversation_chain
# during chat
result = st.session_state.conversation({
"question": user_query,
"chat_history": st.session_state['chat_history']})
```
Result would then lead to the error.
### Expected behavior
Chat is supposed to work instead of getting

Customize how messages are formatted in MessagesPlaceholder
Currently, history messages are always format to:
'''
Human: ...
AI: ...
'''
Popular chat fine-tunings use all sorts of different formats.
Example:
'''
<|im_start|>user
...<|im_end|>
<|im_start|>assistant
...<|im_end|>
'''
There's currently no way to change how history messages are prompted.
### Motivation
I wanted to use langchain to make chatbots. Currently that use case is not well supported.
### Your contribution
Here's how I got it to work. I have to manually parse the history in a previous step.

] | ### Feature request
It would be nice to write code for any generic LLM to use in a given chain, being able to specify its provider and parameters in a config file outside the source code.
Is there a built-in way to do so? What major roadblocks would you see in doing that?
### Motivation
Most examples that I see in the docs or over the Internet tend to specify from code whether the LLM to be used in a given chain has to be from openAI, anthropic, LLaMA, etc., resulting in different codebases, while it would be great to write one single unified codebase and compare the performance of different open-source or API LLMs by simply changing one line of config.
This would be especially relevant when the specific LLM provider is not set or known from the get-go and multiple ones should be compared to find the most suitable one in terms of perfomance, efficiency and cost for any given LLM-driven application.
### Your contribution
I don't have time for a PR now, but since I have been doing a similar thing for our private codebase at the laboratory, combining openAI, anthropic and LLaMA under a single unified spell without using the langchain framework, I may be interested in supporting that in the future as the framework already has lots of interesting features in terms of tooling, memory and storage. | generic codebase? | https://api.github.com/repos/langchain-ai/langchain/issues/14483/comments | 7 | 2023-12-09T07:06:17Z | 2024-04-09T16:14:17Z | https://github.com/langchain-ai/langchain/issues/14483 | 2,033,679,268 | 14,483 |

] | ### Issue with current documentation:
Hi,
I'm trying to understand _**Pinecone.from_documents**_ as shown [here ](https://python.langchain.com/docs/integrations/vectorstores/pinecone).
I saw it used the same way in another tutorial as well and it seems like it should be calling OpenAIEmbeddings.embed_documents at some point and then upserting the texts and vectors to the pinecone index, but I can't find the actual python file for the method or any documentation anywhere.
I'm trying to adapt it and need to understand how **_from_documents_** works. Specifically I am trying to do the following and am curious if the method could be used in this way
My goals:
- Use Pinecone.from_documents(documents, embeddings, index_name=index_name, namespace=namespace) in a for loop where in each iteration namespace change and the "chunked" documents are different. Each namespace represents a different chunking strategy for an experiment.
Note that I defined embeddings=OpenAIEmbeddingsWrapper(model=embedding_model_name) before the for loop, where OpenAIEmbeddingsWrapper is a wrapper class around the OpenAIEmbeddings object, and embedding_model_name="text-embedding-ada-002".
Why I'm asking:
- It seems like the number of texts and vectors that I can extract from OpenAIEmbeddingsWrapper (using the OpenAIEmbeddings.embed_documents method) for each namespace doesn't match what's in Pinecone (610 texts/vectors from the method vs 1251 in Pinecone).
### Idea or request for content:

### Reproduction
https://github.com/langchain-ai/langchain/pull/14266 added a deprecation for `input_variables` argument of `PromptTemplate.from_file`. It was released in 0.0.346.
However, https://github.com/langchain-ai/langchain/blob/v0.0.346/libs/langchain/langchain/chains/llm_summarization_checker/base.py#L20-L31 still uses `input_variables` at the module-level. So now this `DeprecationWarning` is emitted simply for importing from LangChain.
Can we fix this, so LangChain isn't emitting `DeprecationWarning`s?

I expect LangChain to not automatically emit `DeprecationWarning`s when importing from it | DeprecationWarning: `input_variables' is deprecated and ignored | https://api.github.com/repos/langchain-ai/langchain/issues/14467/comments | 1 | 2023-12-08T21:10:46Z | 2023-12-13T01:43:28Z | https://github.com/langchain-ai/langchain/issues/14467 | 2,033,316,778 | 14,467 |

Hi, I'm using the llama2 model for SQL, and I modified it to work directly using LLM. I also added more tables to test the model, and I'm modifying the prompt. When I do this, it generates longer queries based on the question I send, but when the query is very long, it doesn't complete generating everything. I checked the response character count, and on average, it returns around 400+- maximum response characters (I tried increasing and removing the character limit, but it didn't solve the problem).
llm = Replicate(
model=llama2_13b,
input={"temperature": 0.1,
"max_length": 2000,
Incorrect return type.

"hwchase17",
"langchain"
] | During the recent initiative to secure API keys with `SecretStr` (https://github.com/langchain-ai/langchain/issues/12165), some implementations and their corresponding tests were implemented with some flaws. More specifically, they were not really masking the API key.
For instsance, in `libs/langchain/langchain/chat_models/javelin_ai_gateway.py` we have:
```
@property
def _default_params(self) -> Dict[str, Any]:
params: Dict[str, Any] = {
"gateway_uri": self.gateway_uri,
"javelin_api_key": cast(SecretStr, self.javelin_api_key).get_secret_value(),
"route": self.route,
**(self.params.dict() if self.params else {}),
}
return params
```
In the above snippet, `self.javelin_api_key` is cast to `SecretStr`, and then immediately `.get_secret_value()` is invoked, essentially retrieving the original string. Note that Javelin chat lacks unit tests. This could be used to handle the case where the API key is `None`, but then it might appear like there's no masking and it's preferable to address the `None` case directly.
It's worth noting that this pattern is repeated in tests, such as in `libs/langchain/tests/integration_tests/chat_models/test_baiduqianfan.py`:
```
def test_uses_actual_secret_value_from_secret_str() -> None:
"""Test that actual secret is retrieved using `.get_secret_value()`."""
chat = QianfanChatEndpoint(
qianfan_ak="test-api-key",
qianfan_sk="test-secret-key",
)
assert cast(SecretStr, chat.qianfan_ak).get_secret_value() == "test-api-key"
assert cast(SecretStr, chat.qianfan_sk).get_secret_value() == "test-secret-key"
```
The point of the test would be to assert that the API key is indeed a secret, and not just cast it back and forth.
Let me point out that the test suite for baiduqianfan chat does indeed catch whether the API key is indeed masked with a `SecretStr` by capturing the stdout.

import { OpenAIEmbeddings } from 'langchain/embeddings/openai';

const pinecone = new Pinecone();
const indexKey = process.env.PINECONE_INDEX_KEY;
if (!indexKey) {
throw new Error('PINECONE_INDEX_KEY is not set.');
}
const pineconeIndex = pinecone.Index(indexKey);
export async function queryDocuments(query: string, returnSourceDocuments = false) {
const vectorStore = await PineconeStore.fromExistingIndex(
new OpenAIEmbeddings({

);
const model = new OpenAI({

});
const chain = VectorDBQAChain.fromLLM(model, vectorStore, {
k: 5,
returnSourceDocuments,
});
return await chain.call({ query });
}
```
The embeddings have been created and confirmed to exist in the Pinecone console, e.g.:

Hello Team,
We are using opensearch vectordb to store the embeddings, then we are using these embeddings to retrieve the similar document during conversastnal retrieval. while checking the settings of the index created by vector_db.add_text(page_content,metadatas). i have seen the number_of_replicas as 5 and shards as 1(this is the default behaviour of vector_db.add_text(page_content,metadats)
**I want to pass as number_of_replicas as 1** and shards as 1 whenever the index is created on opensearch. Can you please help me with this, how can i custom pass this replicas value. Also i am adding code for better understanding below
In the below code if u see the **langchain vector_db.add_text() in Line 109** creating a index with 5 shards by default. i just want to pass this parameter manually lets say 1 shard. Can u please help me out here. Please let me know if you want any more info to understand my issue.

When utilizing custom_table_info in the sqldatabase instance while employing the create_sql_agent function, it appears that there is an issue where it disregards the sql_db_schema. Currently, it only utilizes either the custom_table_info or the sql_db_schema. This poses a challenge, especially when crucial information, such as identifying which ID column corresponds to other tables, cannot be specified in the custom table info. There is a need for an option to use both the custom table information and the sql_db_schema
table_info={'invoice':" the customer_id in invoice table is referenced to customers table's company_id",}
db=SQLDatabase(engine=dbengine,include_tables=["invoice","customer"],custom_table_info=table_info)
Invoking: `sql_db_schema` with `customer, invoice`
CREATE TABLE customer (
id SERIAL NOT NULL,
key VARCHAR NOT NULL,
company_id VARCHAR NOT NULL,
company_name VARCHAR NOT NULL,
)
/*
1 rows from customer table:
id key company_id company_name
670 CUST-0ab15 17 Aim Inc
*/
the customer_id in invoice table is referenced to customers table's company_id,
It doesnt have the schema of invoice table so generating wrong sql queries
### Motivation
I need both custom_table_info and sql_db_schema to work, as some kinda metadata is needed to specify that is specific to my use cases.

### Reproduction
Description:
The issue encountered revolves around the inability of the retrieval process to filter data based on metadata, specifically focusing on the 'file_name' object in the metadata. The context pertains to utilizing Milvius as the database for the vector store.
Details:
Metadata Structure: The metadata comprises a list of dictionaries, where each dictionary holds key-value pairs containing metadata information. The 'file_name' attribute is utilized for filtration purposes.
Example Metadata List:
[{'page_number': '4', 'file_name': 'Apple_history.pdf', 'source_path': '.../Apple_history.pdf'}, ...]
Applied Options and Observations:
Attempted a approach by directly using a 'filter_query' with the 'file_name'.
filter_query = {"filter": {"file_name": 'samsung.pdf'}, "k": self.top}
retriever = vectorstore.as_retriever(search_kwargs=filter_query) # Retrieval of top k results
result = retriever.get_relevant_documents(agent_query)
Similar observations were made where the retrieval fetched data unrelated to the specified 'samsung.pdf' filename.
### Expected behavior
The anticipated functionality was to filter the retrieval process based on the 'file_name' metadata attribute. In scenarios where there are no chunks associated with the specified 'file_name', the retrieval should ideally return no data. | Retrieval Inability to Filter Based on Metadata in Milvius Database | https://api.github.com/repos/langchain-ai/langchain/issues/14429/comments | 2 | 2023-12-08T04:37:35Z | 2024-03-17T16:10:02Z | https://github.com/langchain-ai/langchain/issues/14429 | 2,031,914,421 | 14,429 |

### Reason to Install litellm
@xavier-xia-99 and I are collaborating on finishing the tasks of #12165 for _libs/langchain/langchain/chat_models/litellm.py_. We have finished the implementation and is adding unit tests to verify our logic when we discovered that we need to include litellm for the unit tests, or `make test` will just skip our newly added unit tests. Yet as we try to add the optional dependency litellm according to the instructions provided in langchain/.github/CONTRIBUTING.md, it shows the following dependency conflict. Hence, we will appreciate any help in addressing this conflict or running the CI. Thank you!

I am using langchain 0.0.316 an trying to create a ElasticsearchStore to do some similarity_search
However, whenever I try to create it (using from_documents or not) I get the following error :
`raise ValueError("check_hostname requires server_hostname")`
This is a SSL error, and I suspect it to be the problem as I cannot use SSL. Somewhere else in the project, I cannot with Python to Elastic using verify_certs = False and everything works perfectly.
Thus I tried to create ElasticsearchStore with the following arguments :
```
db = ElasticsearchStore(texts,
es_url='...',
index_name = '...',
embedding,
ssl_verify = {'verify_certs'=False'})
```
But I still have the error and nothing has changed.
How can I make langchain to initialize Elastic without checking for ssl certificates ?

Hello community,
I'm currently working on a project that involves using the langchain library for natural language processing. I'm encountering an issue with the LLMChain class, and I'm hoping someone can help me troubleshoot.
I've initialized a Hugging Face pipeline and constructed a prompt using PromptTemplate. However, when I attempt to load a QA chain using the load_qa_chain function, I get a ValidationError related to the Runnable type. The error suggests that an instance of Runnable is expected, but it seems there's a mismatch.
Here's a simplified version of my code:
```
from langchain.prompts import PromptTemplate
from langchain import load_qa_chain
from transformers import HuggingFacePipeline
hf = HuggingFacePipeline.from_model_id(
model_id="ai-forever/rugpt3large_based_on_gpt2",
task="text-generation",
pipeline_kwargs={"max_new_tokens": 10},
)
prompt = """Question: {question}
Answer: {text}"""
# The next line is where the error occurs
chain = load_qa_chain(hf(prompt=prompt), chain_type="stuff")
```
```
ValidationError: 2 validation errors for LLMChain
llm
instance of Runnable expected (type=type_error.arbitrary_type; expected_arbitrary_type=Runnable)
llm
instance of Runnable expected (type=type_error.arbitrary_type; expected_arbitrary_type=Runnable)
```
I have checked the documentation and versions of the libraries, but I'm still having trouble understanding and resolving the issue. Could someone please provide guidance on what might be causing this ValidationError and how I can address it?
Thank you in advance for your help!

How does conversationbuffermemory works with routerchain for suppose if I wanted to create a chat application I need memory to store the conversations how does that thing work with routerchain?
I'm currently using the same implementation that has shown in the documentation
please respond as soon as possible
thank you:))

### Reproduction
I noticed that the **OutputFixingParser** class does not work when applied to a **PydanticOutputParser** class.
Something has probably changed in **Pydantic**.
Doing step-by-step debugging, I saw that in **PydanticOutputParser**, at line 32 (see below)...
...the exception caught is indeed a **ValidationError**, but _it is not the same_ **ValidationError**...
The **ValidationError** expected from that `try..except` block is of this type.
While the **ValidationError** raised is of this other type.
### Expected behavior
I therefore imagine that the **LangChain** code needs to be updated to also handle the new exception (since the old one belongs to a "**v1**" package). | OutputFixingParser does not work with PydanticOutputParser | https://api.github.com/repos/langchain-ai/langchain/issues/14387/comments | 2 | 2023-12-07T09:01:20Z | 2024-03-17T16:09:31Z | https://github.com/langchain-ai/langchain/issues/14387 | 2,030,232,645 | 14,387 |

### Reproduction
Hi there!
I'm currently exploring the index feature in Langchain to load documents into the vector store upon my app startup.
However, I've encountered an issue where the index doesn't delete old documents when utilizing Redis as the vector store. After some investigation, I discovered that the `delete` function in `langchain.vectorstores.redis.base.Redis` is a static method, which poses a limitation—it cannot access instance variables, including the essential `key_prefix`. Without the `key_prefix`, Redis is unable to delete documents correctly.
This leads me to question why the `delete` method of the Redis vector store is static. I've noticed that other vector stores, such as Pinecone, do not have a static `delete` function and seem to handle this differently.
### Expected behavior
index with Redis as vector store should delete documents correctly.
