] | ### System Info
infra - sagemaker
model - model deployed with `HuggingFaceModel(...).deploy()`
langchain version - v0.0.233
chain types used - RetrievalQA, load_qa_chain
I have a huggingface model deployed behind a sagemaker endpoint which produces outputs as expected when run prediction against it directly. However, when I initialize it with SagemakerEndpoint class from langchain, it only return two characters and sometimes an empty string. I scoured through the internet and langchain docs for the last couple days and my initialization and chain prompting aspects of the code seem to be in line with the docs guidelines and anecdotal recommendations laid out.
I think this either a lack integration support for huggingface models deployed with sagemaker or I'm missing something here that's not been written in the docs and examples. Please review and let me know either way.
### Below code will reproduce the behavior I'm experiencing.
```
from langchain import SagemakerEndpoint
from langchain.llms.sagemaker_endpoint import ContentHandlerBase, LLMContentHandler
endpoint = "xxxxxx-2023-07-14-05-34-901"
parameters = {
"do_sample": True,
"top_p": 0.95,
"temperature": 0.1,
"max_new_tokens": 256,
"num_return_sequences": 4,
}
class ContentHandler(LLMContentHandler):
content_type = "application/json"
accepts = "application/json"
def transform_input(self, prompt: str, model_kwargs: Dict) -> bytes:
input_str = json.dumps({"inputs": prompt, **model_kwargs})
return input_str.encode('utf-8')
def transform_output(self, output: bytes) -> str:
response_json = json.loads(output.read().decode("utf-8"))
return response_json[0]['generated_text']
content_handler = ContentHandler()
sm_llm=SagemakerEndpoint(
endpoint_name=endpoint,
region_name="us-west-2",
model_kwargs= parameters,
content_handler=content_handler,
)
vectordb = Chroma(persist_directory="db", embedding_function=embedding, collection_name="docs")
retriever = vectordb.as_retriever(search_kwargs={'k':3})
print("retriever: ", retriever)
qa_chain = RetrievalQA.from_chain_type(llm=sm_llm,
chain_type="stuff",
retriever=retriever,
return_source_documents=True)
```
#### Here's the output (or lack thereof) from prompting with langchain, in above code.
```
system_prompt = """<|SYSTEM|># Your are a helpful and harmless assistant for providing clear and succinct answers to questions."""
question = "What is your purpose?"
query = (system_prompt + "<|USER|>" + question + "<|ASSISTANT|>")
llm_response = qa_chain(query)
print(llm_response['result'])
---------------------------------------------------------------------------
Output:
Use the following pieces of context to answer the question at the end. If you don't know the answer, just say that you don't know, don't try to make up an answer.
<some doc context from vectordb goes here - removed due to info sensitivity>
Question: # <|SYSTEM|># Your are a helpful and harmless assistant for providing clear and succint answers to questions.
What is your purpose?
Helpful Answer:
```
As shown above, there's no output for 'Helpful Answer: '.
#### However when I prompt the model directly with a predictor like below, it returns the full output as expected.
### Model returns the full output with the below code which runs direct prediction against the endpoint.
```
import boto3
from sagemaker.huggingface import HuggingFacePredictor
from sagemaker.session import Session
sm_session = Session(boto_session=boto3.session.Session())
payload = {
"inputs": "What is your purpose?",
"parameters": {"max_new_tokens": 256, "do_sample": True}
}
local_llm = HuggingFacePredictor(endpoint, sm_session)
chat = local_llm.predict(data=payload)
result = chat[0]["generated_text"]
print(result)
```
#### Output for direct prediction from the code executed above.
```
What is your purpose?
You seem important. What is your value? What can you do that makes you unique? What is your unique value?
* You are important to the people who know you best.
* When you accomplish the things you want to do, you will become valuable to the people who matter to you.
* We value you because you are special
```
As it can be seen above, the model returns an output (not a great one) but the fact is it does when I'm prompted and not when wrapped with SagemakerEndpoint class and prompted with prompted with langchain.

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

Tried the above code which is based on the Retrieval Augmented Generation pipeline. I tried with different configurations of vectordbs(**chroma,pinecone,fiass,weaviate...etc**), different configurations of embedding methods(**openai embeddings,huggingface embedding,sentencetransformer embedding,...etc**) , and also different configurations of LLMs(**openai,Azureopenai,Cohere, Huggingface model...etc**).
But in all the above cases I am observing some major/critical miss behaviors in some times
**1 - When I ask questions related to the document that I provided(in the pdf which was embedded and stored in the vector store), sometimes I am getting the expected answers from the document - which are the expected behaviors that should occur always.**
**2 - But When I ask questions related to the document that I provided, sometimes I am getting the answers which are out of the document.**
**3 - And When I ask questions related to the document that I provided, I get the correct answers from the document and also the outer world answers**
**4 - Also If I ask questions that are not related to this document, still I am getting answers from the outer world(I am expecting an answer such as - "I don't know, the question is beyond my knowledge" from the chain**
**5 - Sometimes I am getting the internal states (Agent response, human response, training data context, internal output, langchain prompt, answer containing page number with full context, partial intermediate answers......)- which I don't want to look, along with the output -**
**6 - Finally each time I am getting different results for the same question.**
Tried verbose= False. But still getting some unwanted details(along with the exact answer) which makes the bot noisy.
How to prevent it?
### Expected behavior
When I ask questions related to the document that I provided, it must return the most relevant answer without any other info like internal states, prompts...etc.
Also if I ask questions that are not related to the document that I provided it shuld return "I don't know, the question is beyond my knowledge" | Getting unwanted/irrelevant/out of context results in document question answering | https://api.github.com/repos/langchain-ai/langchain/issues/7702/comments | 8 | 2023-07-14T12:38:13Z | 2023-12-19T16:23:01Z | https://github.com/langchain-ai/langchain/issues/7702 | 1,804,812,396 | 7,702 |

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

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

Here is an (incomplete) modification of the documentation for using `CombinedMemory`, but with `VectorStoreRetrieverMemory` instead of `ConversationSummaryMemory`.
```python
from langchain.llms import OpenAI
from langchain.prompts import PromptTemplate
from langchain.chains import ConversationChain
from langchain.memory import (
ConversationBufferMemory,
CombinedMemory,
ConversationSummaryMemory,
)
conv_memory = ConversationBufferMemory(
memory_key="chat_history_lines", input_key="input"
)
# not shown: define retriever as shown in the [Chroma docs](https://python.langchain.com/docs/modules/data_connection/vectorstores/integrations/chroma)
vector_memory = VectorStoreRetrieverMemory(retriever=retriever, memory_key="history", input_key="input")
# Combined
memory = CombinedMemory(memories=[vector_memory, summary_memory])
_DEFAULT_TEMPLATE = """The following is a friendly conversation between a human and an AI. The AI is talkative and provides lots of specific details from its context. If the AI does not know the answer to a question, it truthfully says it does not know.
Summary of conversation:
{history}
Current conversation:
{chat_history_lines}
Human: {input}
AI:"""
PROMPT = PromptTemplate(
input_variables=["history", "input", "chat_history_lines"],
template=_DEFAULT_TEMPLATE,
)
llm = OpenAI(temperature=0)
conversation = ConversationChain(llm=llm, verbose=True, memory=memory, prompt=PROMPT)
```
What happens is, [on this line](https://github.com/hwchase17/langchain/blob/master/langchain/memory/vectorstore.py#L58), `inputs.items()` looks something like this:
```python
dict_items([('input', 'How are you?'), ('chat_history_lines', 'Human: wow\nAI: Wow!'), ('history', 'Human: wow\nAI: Wow!\nHuman:yes\nAI: Yes!\nHuman: hello\nAI: Hi!')])
```
When adding documents to the vectorstore retriever memory, all items are added except for `self.memory_key` (history). Thus, `chat_history_lines` is included in the created documents, without a way to prevent that.
### Suggestion:
One approach for supporting this would be to add a property to VectorStoreRetrieverMemory that allows the caller to specify which input keys should be included in the created documents. Another approach may be to only create documents with input_key from inputs. | Issue: Cannot use CombinedMemory with VectorStoreRetrieverMemory and ConversationTokenBufferMemory | https://api.github.com/repos/langchain-ai/langchain/issues/7695/comments | 10 | 2023-07-14T06:05:24Z | 2023-08-03T15:00:56Z | https://github.com/langchain-ai/langchain/issues/7695 | 1,804,243,856 | 7,695 |

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

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

I have a case,that there are many tools to be used, so i can't put them all in prompt, is there any good ideas, retrievers, to filtrate the tools?
and i have try the embedding, vector_store ,but it can not filtrate all tools i need, and it can't filtrate the tools which are Indirectly dependent to the user query
is there any better retrievers?

db = Chroma(client=client, collection_name="my_collection")

### Reproduction
tl;dr: chroma no longer supports `{}` metadata which breaks `.addtexts()`: https://github.com/chroma-core/chroma/issues/791#issuecomment-1630909852
I have written this code to try using a Chroma db for memory in a ConversationChain (based on this example: <https://python.langchain.com/docs/modules/memory/how_to/vectorstore_retriever_memory>):
```python
db = Chroma(persist_directory=local_dir_path, embedding_function=OpenAIEmbeddings())
retriever = db.as_retriever(search_kwargs=dict(k=1))
memory = VectorStoreRetrieverMemory(retriever=retriever)
llm_chain = ConversationChain(
llm=OpenAIModel(**open_ai_params),
prompt=prompt,
memory=memory,
verbose=True,
)
chain = SimpleSequentialChain(chains=[moderation_chain, llm_chain]
chain.run(input="hello")
```
However, I get an error `ValueError: Expected metadata to be a non-empty dict, got {}`
I see `langchain/vectorstores/base.py` in the stack trace, and add logging:
```python
def add_documents(self, documents: List[Document], **kwargs: Any) -> List[str]:
"""Run more documents through the embeddings and add to the vectorstore.
Args:
documents (List[Document]: Documents to add to the vectorstore.
Returns:
List[str]: List of IDs of the added texts.
"""
# TODO: Handle the case where the user doesn't provide ids on the Collection
texts = [doc.page_content for doc in documents]
metadatas = [doc.metadata for doc in documents]
print(f"texts: {texts}")
print(f"metadata: {metadatas}")
print(f"kwargs: {kwargs}")
return self.add_texts(texts, metadatas, **kwargs)
```
which logs out
```
texts: ['input: test\nresponse: Hello! How can I assist you today?']
metadata: [{}]
kwargs: {}
```
If I edit the source code to pass `None`, then `self.add_texts` works as expected.
```
metadatas = [doc.metadata for doc in documents]
if all(not metadata for metadata in metadatas): # Check if all items in the list are empty

I'm looking for efficient ways to handle different types of tasks in my chatbot. Some questions require DataFrame responses, others need text responses, and some require both. Can I create specialized agents to handle specific tasks separately instead of specifying everything in one prompt?

Hi my data has 10 rows and I tried with both pandas and csv agent, in the observations I can see the agents are able to process all rows, but in the final answer both agents only output the first 5 rows from df.head(). I tried to set 'number_of_head_rows' to 10 but it doesn't work. Is there any way to make the agents to show results from all rows rather the the head?

### Reproduction
I want to create a chatbot to retrieve information from my own pdf in response to a query using google PaLM model, I followed these steps :
-load the pdf
-split it using RecursiveCharacterTextSplitter
-store its embeddings in a Chroma vectorestore
and then create a chain ...
```
from langchain.document_loaders import PyPDFLoader
from langchain.document_loaders import PyPDFLoader
from langchain.text_splitter import RecursiveCharacterTextSplitter
from langchain.vectorstores import Chroma
from langchain.embeddings.openai import OpenAIEmbeddings
import langchain
loader=PyPDFLoader("path/to/pdf.pdf")
chroma_dir="./chroma
pages=loader.load()
splitter=RecursiveCharacterTextSplitter(
chunk_size=1000,
chunk_overlap=150,
separators=['\n\n','\n'," ",""]
)
splits=splitter.split_documents(pages)
#I want to change this with another embedding method which doesn't require API authentification
embeddings=OpenAIEmbeddings()
vector_db=Chroma.from_documents(
documents=splits,
embedding=embeddings,
persist_directory=chroma_dir
)
```
But the only embedding method that is available in the LangChain documentation is OpenAIEmbeddings,how can we do without it?
### Expected behavior
all the splits embeddings stored in Chroma vectorestore without using OpenAIEmbeddings() | Is it possible to use open source embedding methods rather than OpenAIEmbeddings? | https://api.github.com/repos/langchain-ai/langchain/issues/7619/comments | 2 | 2023-07-12T21:32:46Z | 2024-04-26T12:42:21Z | https://github.com/langchain-ai/langchain/issues/7619 | 1,801,791,302 | 7,619 |

from langchain import PromptTemplate
from langchain.chains import LLMChain
from langchain.chat_models import ChatOpenAI
import os
from dotenv import load_dotenv
import json

print(model_path)
# Load the model

#triple_template.format(text=t)
chain = LLMChain(llm=llm, prompt=triple_template)
#Run the model
print("RUnning Model.....")
print(chain.run(text=text))
I have commented out llm generated by ChatOpenAI, this code executes and gives desired results if we use OpenAI LLM. However, I am using LLaMa vicuna-7b-1.1.ggmlv3.q4_0.bin, the chain gives the following error -

llm
value is not a valid dict (type=type_error.dict)
I have tested the LLaMa LLM, it works outside LLM chain without any problem.
### Expected behavior
In response to the given text, it should have returned a semantic triple of form ( Subject, Predicate Object) ie.

# Issue
`convert_to_openai_function` does not work as intended:
- Classes are not supported
- Any function without its source is not supported

### Expected behavior
When calling `langchain.chains.openai_functions.base.convert_to_openai_function`, the subsequent call to `_get_python_function_name` fails because it tries to read source code (and cannot find it).

It's unclear how to check your langchain version, I can instead detail the steps I have taken.
I am running python 3.10.6 and python 3.11.4
I have uninstalled and reinstalled both versions individually, in path, and attempted to install and run langchain with just one of either of those two versions installed.
I have installed in both instances 'pip install langchain' uninstalled and reinstalled as 'langchain[all]', ran 'pip install --upgrade langchain[all]'.
I am running this in a streamlit environment with the latest version installed by pip.
the line I am having issue with is:

Hi, LangChain community,
just to share that even with the examples mentioned in the official documentation, it is almost impossible to get consistent results when using agents with Wikipedia/Google search tools. Or the search is non conclusive or the LLM is totally hallucinating at the very early step of the pipeline. LLMs from OpenAI for Completion or Conversation.
Did someone else notice this new behavior?
Best regards
Jerome

### Reproduction
I am using the "**ConversationalRetrievalChain**", Whenever I send a message to a model, it produces wrong results with history, whereas if I send the same message without history, it produces correct results. The issue here is that the model is forming the wrong standalone question, and the same wrong standalone question is passing to the OpenAI Model.
Steps to reproduce:
1. Use the Conversational Retrieval Chan
2. Pass the history on to the chain.
3. Send the "Hello" message continuously.
Here you can observe wrong/weired answers.
The above scenario is Just an example. But whenever we ask some question, immediately if we send the message "Hello", the "conversational retrieval chain" forms the wrong standalone question, hence the openAI model producing wrong answers.
This is the code I am using: -
_template = """
Use the following pieces of context to answer the question at the end.
{context}
If you still cant find the answer, just say that you don't know, don't try to make up an answer.
You can also look into chat history.
{chat_history}
Question: {question}
Answer:
"""
CONDENSE_QUESTION_PROMPT = PromptTemplate(
template=_template,
input_variables = ["context","question", "chat_history"],
)
chain = ConversationalRetrievalChain.from_llm(
llm= azure_chat_api_llm_objct,
retriever=vectors.as_retriever(),
verbose=True,
chain_type="stuff",
memory = memory,
get_chat_history=lambda h:h,
# condense_question_prompt=CONDENSE_QUESTION_PROMPT,
combine_docs_chain_kwargs={"prompt": CONDENSE_QUESTION_PROMPT},
return_generated_question=True,
)
chain.run("Hello")
Note:- I have tried multiple way like removing "CONDENCE_QUESTION", without prompt, with different types of prompts, etc..but still its producing wrong standalone question.
Ex:-
_template = """
Given the following conversation and a follow up question, rephrase the follow up question to be a standalone question.
Chat History:
{chat_history}
Follow Up Input: {question}
Standalone question:
"""
Thanks in advance, and please correct me if I made any mistakes in the code.

] | ### Issue you'd like to raise.
I'd like to understand if there is a way to have from OpenAI response a **list of values** (string or objects: it's the same) of a **fixed length**. I read the documentation here: https://python.langchain.com/docs/modules/model_io/output_parsers/comma_separated but I didn't find anything related to a length (maybe it's not possible?). Indeed I understood that probably these parsers only add a well-formatted piece of prompt, but you don't have the safety to have the expected results.
In my use case, I have a list of texts and I want to have a title on each of them. My prompt is something like that:
```
####
Text 1:
- Bla bla bla
...
Text 8:
- Bla bla bla
###
Use these texts to generate a title for each text. The number of the titles must be 8.
```
At the end of the prompt I "force" the number to the number of the expected results with the same number of the text, but sometimes the model gives me more titles (above all when the number of texts is 1).
So I thought to use these parsers. But I don't find any constraints on the length of the results, the only thing is a validator to check if the length is correct.
### Suggestion:
_No response_ | Output parser set number of list result | https://api.github.com/repos/langchain-ai/langchain/issues/7598/comments | 3 | 2023-07-12T13:31:51Z | 2023-10-19T16:06:03Z | https://github.com/langchain-ai/langchain/issues/7598 | 1,800,994,485 | 7,598 |

Hello Langchain community!
I'm currently in the process of developing a company's chatbot, and I've chosen to use both a CSV file and Pinecone DB for the project.
Here's a basic outline of the structure I've adopted so far:
I've managed to set the two tools, and its example usage has been providing accurate answers
the first tool gets me the answers based on pandas’s result from the example usage, the answers are based on csv and it’s correct in all cases
Also set the second tool and its example usage is answered correctly.
until here things are very promising and i expected everything to work as it is.
so i have set the LLM and combined the two tools and used agent
However, when I combined both tools using an agent, the answers started to deviate from the expected output. I'm not entirely sure whether the method I'm using to utilize the agent is optimal.
To address this issue, I've experimented with the MultiretrievalQA chain using vector embedding. But the results are not consistently reliable, and moreover, I'd rather not generate new embeddings every time I modify the CSV.
Is there anyone in the community who can shed light on these issues I'm encountering? Any feedback on my current approach, suggestions on how to optimize it, or alternative strategies would be greatly appreciated!
Thank you.
### Motivation
I'm making a company's gpt and i hope to link my csv with the chatbot so that whenever i change the csv the chatbot is automatically linked with it

In `VectorStore`/`VectorStoreRetriever` class, `_similarity_search_with_relevance_scores`function,
1) Allow different choices of threshold kind: allow users to choose whether >= threshold or <= threshold
2) Allow users to choose to return the relevance score along with the docs
### Motivation
I am working with returning relevant docs that satisfy a certain threshold, and I encountered some problems.
One problem is that for different embedding algorithms and similarity calculations, it is not always the case that higher relevance scores are better. Actually, when I use `HuggingFaceEmbedding` with `Chroma` database, the smaller the relevance score, the better. So I believe it would be necessary to allow users choose between different options here.
The second problem is that I want to see the relevance score, however, in https://github.com/hwchase17/langchain/blob/master/langchain/vectorstores/base.py, line 474 to 492, it is fixed that only the docs are finally returned.

def _get_relevant_documents(
self, query: str, *, run_manager: CallbackManagerForRetrieverRun
) -> List[Document]:
if self.search_type == "similarity":
docs = self.vectorstore.similarity_search(query, **self.search_kwargs)
elif self.search_type == "similarity_score_threshold":
docs_and_similarities = (
self.vectorstore.similarity_search_with_relevance_scores(
query, **self.search_kwargs
)
)
docs = [doc for doc, _ in docs_and_similarities]
elif self.search_type == "mmr":
docs = self.vectorstore.max_marginal_relevance_search(
query, **self.search_kwargs
)
else:
raise ValueError(f"search_type of {self.search_type} not allowed.")
return docs
```
I wish there is an option that the relevance scores could also be returned.

### Reproduction
For now, there are only the default `ConversationalChatAgent` and `ConversationalAgent`, and we cannot create custom prompt templates in them. At least, I don't see how to do that in both the docs and source code.
I think there should be a straight-forward way to do so, just like how you can have a [custom LLM agent](https://python.langchain.com/docs/modules/agents/how_to/custom_llm_chat_agent):
```py
agent = LLMSingleActionAgent(
llm_chain=llm_chain,
output_parser=output_parser,
stop=["\nObservation:"],
allowed_tools=tool_names
)
```
However, when the same code is applied to `ConversationalChatAgent`, that is:
```py
agent = LLMSingleActionAgent(
llm_chain=llm_chain,
output_parser=output_parser,
stop=["\nObservation:"],
allowed_tools=tool_names
)
```
I get the following error:
```shell
pydantic.error_wrappers.ValidationError: 1 validation error for ConversationalChatAgent
__root__
Got unexpected prompt type <class '__main__.CustomPromptTemplate'> (type=value_error)
```
I'm not sure if this belongs to **Bug Report** so if I'm doing anything wrong, please tell me about it. Thanks!

Is there an example where we can configure multiple databases as different tools and query them. It seems possible, but in my case, what ever question I ask, it always goes to the first Tool. Not sure what is the problem.

MLflow also uses sqlalchemy to handle sqlite-based storage, and calls `sqlalchemy.orm.configure_mappers()` during initialization. With langchain>=0.0.228, MLflow fails to start. All MLflow users who choose sqlite-based storage cannot use it with langchain.

[

] | ### Feature request
There are tools with `func` but whose implementation of coroutine would be just same. E.g.,
```python
def adder(x, y):
return x+y
async def aadder(x, y):
return x+y
adder_tool = Tool(func=adder, coroutine=aadder, ...)
```
I have to define `adder` and `aadder` redundantly.
Of course the logic can be abstracted within the two definitions, but I'd prefer just having the same function and reuse the `func` at the async calling. A possible implementation would look like this
at [this line](https://github.com/hwchase17/langchain/blob/master/langchain/tools/base.py#L453C1-L473C65)
```python
async def _arun(
self,
*args: Any,
run_manager: Optional[AsyncCallbackManagerForToolRun] = None,
**kwargs: Any,
) -> Any:
"""Use the tool asynchronously."""
if self.coroutine:
...
elif self.default_coroutine: # introducing some parameter
return self.run(*args, run_manager=run_manager, **kwargs)
raise NotImplementedError("Tool does not support async")
```
with this the adding `adder` will look like this:
```python
def adder(x, y):
return x+y
adder_tool = Tool(func=adder, default_coroutine=True, ...)
```
### Motivation
Simplify function documentations
### Your contribution
I can make a PR as proposed if it's the right approach. | Use `func` as a default `coroutine` method in Tool instantiation | https://api.github.com/repos/langchain-ai/langchain/issues/7558/comments | 2 | 2023-07-11T19:23:13Z | 2023-10-17T16:04:49Z | https://github.com/langchain-ai/langchain/issues/7558 | 1,799,618,568 | 7,558 |

] | ### Feature request
Introduce a follow-up query recommender callback to enhance user experience and engagement in case of chatbot use case.
The recommender callback will suggest relevant follow-up queries generated by LLM based on the user's conversation history, facilitating smoother interactions.
The proposed flow is as follows:
- Utilize the configured memory to recommend follow-up queries by analyzing the chat history.
- In the absence of configured memory, leverage the current question and answer to suggest follow-up queries.
Usage: It's up to the user how they want to utilize these recommended queries
### Motivation
The inclusion of this feature would greatly benefit various chatbot use cases.
By suggesting follow-up queries, the chatbot can proactively guide the conversation, helping users navigate complex interactions more efficiently. This feature has the potential to enhance user satisfaction and streamline the overall user experience. While the exact extent of its usefulness may vary, it is a valuable addition that can significantly improve the chatbot's capabilities.

"langchain-ai",
"langchain"
] | ### System Info
LangChain 0.230
python 3.10
From first example of using calculator from: https://learn.deeplearning.ai/langchain/lesson/7/agents
> Entering new chain...
ACTION: json
{
"action": "Calculator",
"action_input": "25% of 300"
}
The text is what the ChatOutputParser in agents/chat/output_parser.py gets (I prefixed it with ACTION in my print statement).
The word 'json' is now prefixing the JSON blob from the ChatOpenAI LLM which causes the agent to fail. One possible solution that I verified work but not sure if it's the right one is checking if it prefixes with json and just remove that:
if action.startswith("json"):
action = action[4:]
This seems to work and lets both the first two examples in the tutorial work.

i convert the dictionary in a json string
```python
json_string = json.dumps(dict)
```
and i obtain the following string
```json

Accessing many corporate resources requires special authentication, e.g. Kerberos.
The `requests` library supports passing an auth object, e.g.
`requests.get(url, auth=HttpNegotiateAuth(), verify=False)` to use SSPI.
We're able to pass a `requests_wrapper `to `LLMRequestsChain`, but it only allows changing headers, not the actual get method that is used.
### Suggestion:
Allow for more generic generic wrappers to be passed? Allow passing a requests-compatible auth object? | Issue: Passing auth object to LLMRequestsChain | https://api.github.com/repos/langchain-ai/langchain/issues/7542/comments | 0 | 2023-07-11T13:59:38Z | 2023-07-14T12:38:25Z | https://github.com/langchain-ai/langchain/issues/7542 | 1,799,011,449 | 7,542 |

I am trying to query the documents using the below stack
**Langchain+ embedding tool + vectore store + LLM model**
There are many tools and techniques for this in langchain including **load_qa_chain, RetrievalQA,VectorstoreIndexCreator,ConversationalRetrievalChain**. Those are already giving the good results(Not optimal)
But found one more technique including **VectorStoreInfo,VectorStoreToolkit and vectorstore_agent**
What is the advantage/Importance of this pipeline which using **VectorStoreInfo,VectorStoreToolkit and vectorstore_agent** over the other which doesnt follow this pipeline(use any of **load_qa_chain, RetrievalQA,VectorstoreIndexCreator,ConversationalRetrievalChain**)

### Reproduction
I am following this tutorial on structured output https://python.langchain.com/docs/modules/model_io/output_parsers/structured
I am passing my openai API key from config, I have made sure that it is being passed as I can see the output of the `chat_model` instance...
```python
from langchain.output_parsers import StructuredOutputParser, ResponseSchema
from langchain.prompts import PromptTemplate, ChatPromptTemplate, HumanMessagePromptTemplate
from langchain.chat_models import ChatOpenAI
from config import config
response_schemas = [
ResponseSchema(name="answer", description="answer to the user's question"),
ResponseSchema(name="source", description="source used to answer the user's question, should be a website.")
]
output_parser = StructuredOutputParser.from_response_schemas(response_schemas)
format_instructions = output_parser.get_format_instructions()
prompt = PromptTemplate(
template="answer the users question as best as possible.\n{format_instructions}\n{question}",
input_variables=["question"],
partial_variables={"format_instructions": format_instructions}
)
chat_model = ChatOpenAI(temperature=0, openai_api_key=config.OPENAI_API_KEY)
print(chat_model)
prompt = ChatPromptTemplate(
messages=[
HumanMessagePromptTemplate.from_template("answer the users question as best as possible.\n{format_instructions}\n{question}")
],
input_variables=["question"],
partial_variables={"format_instructions": format_instructions}
)
_input = prompt.format_prompt(question="what's the capital of france?")
print(_input.to_messages())
output = chat_model(_input.to_messages())
print(output)
print(output_parser.parse(output.content))
```
### Expected behavior
The expected output of the code should be

[
"langchain-ai",
"langchain"
] | ### Feature request
The sql agent should query in a manner that it gets **unique** values as sample data (metadata) instead of all values. Only then will it be able to understand which columns to query from. Otherwise, it might get confused between similar-sounding column names (ex: age, age_group)
### Motivation
Databases are typically very sparse (several columns are null). In such cases, the sql agent will perform poorly. The reason is it uses the InfoSQLDatabaseTool(sql_db_schema) to get all sample rows from the database. If the values are themselves null, then it doesn't get an accurate idea of what each column is supposed to contain. This would affect the query generation and the checking part too.

I am trying to integrate confluence for open ai embedding and vector store using in memory doc-array.
I am sure this must not be issue Langchain but thought of posting here . Any pointer would really appreciated.
I created one free trial version account with atlassian.com and trying one POC with confluence pages.

loader = ConfluenceLoader(url="https://yogeshdeshmukh.atlassian.net/wiki",
token="XXXX")
documentLoaders = documentLoaders + loader.load(space_key="YYYY", include_attachments=False, limit=10)

Is it possible to use open source LLM models in SQL chain ?

Error:
```

Are there any samples/snippets are available for using open source LLM models in SQL Chain ?

```
tokenizer = TapexTokenizer.from_pretrained("microsoft/tapex-base-finetuned-wtq")

I tested the enable_limit to True and asking thins like
1. Get 3 residents who were born in xxx
2. Get 5 Residens who were bon in xxx
It works pretty well.
However in my use case, users can ask also: List all the residents who were born in xxx.

```
df = loadSqlData()

And now I am trying to make a chatbot with my SQL Table, I dont want to use SQLToolkit or Agent as its very slow.
so I am trying to use the following code:
```
llm = AzureChatOpenAI(

openai_api_version=OPENAI_API_VERSION ,
deployment_name=OPENAI_DEPLOYMENT_NAME,
openai_api_key=OPENAI_API_KEY,
openai_api_type = OPENAI_API_TYPE ,
model_name=OPENAI_MODEL_NAME,
temperature=0)
embed = OpenAIEmbeddings(deployment=OPENAI_EMBEDDING_DEPLOYMENT_NAME, model=OPENAI_EMBEDDING_MODEL_NAME, chunk_size=1)
user_input = get_text()
vectorstore = Pinecone.from_existing_index("cubigo",embedding=embed, namespace="vwProfiles2")
docs =vectorstore.similarity_search_with_score(user_input, k=250, namespace="vwProfiles2") #Who is from Bransk
vectordb = Pinecone.from_documents(documents=docs,
embedding=embed)
qa = RetrievalQA.from_chain_type(llm=llm,
chain_type="stuff",
retriever=vectordb.as_retriever()
)
response = qa.run(user_input)
```
But I get this error

I'm using langchain 0.0.218 in python 3.10.0 and when I use glob patterns as a direct argument to initialize the class this does not load anything. e.g. DirectoryLoader(path = root_dir + 'data', glob = "**/*.xml")
But when I use it in loader_kwargs it works perfect.
e.g. DirectoryLoader(path = path, loader_kwargs={"glob":"**/*.xml"}
May this be a bug that when class is initialized in the line?https://github.com/hwchase17/langchain/blob/master/langchain/document_loaders/directory.py#L33
It seems to always be set as "**/[!.]*" when using it as an arg but not when using it inside loader_kwargs

### Reproduction
1. Make a directory called data
2. Inside that directory store all kind of supported documents (docx, text, etc) excepting -for example- xml files and also a folder that only contains all the xml files
3. Use loader = Directoryloader = (path = root_dir + 'data', glob = "**/*.xml")
5. execute loader.load() will not load any documents
Then use loader = DirectoryLoader(path = path, loader_kwargs={"glob": "**/*.xml"}
loader.load() and will work perfectly
### Expected behavior
Must work using it like loader = Directoryloader(path = root_dir + 'data', glob = "**/*.xml")
*NOTE* This happens with all kind of glob patterns passed through glob argument. It does not has to do with the file extension or something.

I keep getting OutputParserException: Could not parse LLM output.
I have tried setting handle_parsing_errors=True as well as handle_parsing_errors="Check your output and make sure it conforms!", and yet most of the times I find myself getting the OutputParserException.
Here is an example of the error:
```
> Entering new chain...
Thought: The question is asking for a detailed explanation of a use example of chain of thought prompting. I should first check if there is a clear answer in the database.
Action: Lookup from database
Action Input: "use example of chain of thought prompting"
Observation: Sure! Here's an example of chain-of-thought prompting:
Let's say we have a language model that needs to solve a math word problem. The problem is: "John has 5 apples. He gives 2 apples to Mary. How many apples does John have now?"
With chain-of-thought prompting, we provide the model with a prompt that consists of triples: input, chain of thought, output. In this case, the prompt could be:
Input: "John has 5 apples. He gives 2 apples to Mary."
Chain of Thought: "To solve this problem, we need to subtract the number of apples John gave to Mary from the total number of apples John had."
Output: "John now has 3 apples."
By providing the model with this chain of thought, we guide it through the reasoning process step-by-step. The model can then generate the correct answer by following the provided chain of thought.
This approach of chain-of-thought prompting helps the language model to decompose multi-step problems into intermediate steps, allowing for better reasoning and problem-solving abilities.
Thought:

Is there any other way in which I can mitigate this problem to get consistent outputs?
### Suggestion:
Is there a way to use Retry Parser for this agent, if yes how? | MRKL Agent OutputParser Exception. | https://api.github.com/repos/langchain-ai/langchain/issues/7493/comments | 6 | 2023-07-10T18:46:36Z | 2024-03-21T16:04:42Z | https://github.com/langchain-ai/langchain/issues/7493 | 1,797,326,865 | 7,493 |

<sup>Originally posted by **aju22** July 9, 2023</sup>
Here is the code I'm using for initializing a Zero Shot ReAct Agent with some tools for fetching relevant documents from a vector database:
```
chat_model = ChatOpenAI(
model_name="gpt-3.5-turbo",
temperature="0",
openai_api_key=openai_api_key,
streaming=True,
# verbose=True)
llm_chain = LLMChain(llm=chat_model, prompt=prompt)
agent = ZeroShotAgent(llm_chain=llm_chain, tools=tools, verbose=True, handle_parsing_errors=True)
agent_chain = AgentExecutor.from_agent_and_tools(
agent=agent, tools=tools, verbose=True, memory=memory
)
```
However when I query for a response.
```
query = "Can you explain a use case example of chain of thought prompting in detail?"
res = agent_chain(query)
```
This is the response I get back:
```
> Entering new chain...
Thought: The question is asking for a detailed explanation of a use example of chain-of-thought prompting.
Action: Lookup from database
Action Input: "use example of chain-of-thought prompting"
Observation: Sure! Here's an example of chain-of-thought prompting:
Let's say we have a language model that is trained to solve math word problems. We want to use chain-of-thought prompting to improve its reasoning abilities.
The prompt consists of triples: input, chain of thought, output. For example:
Input: "John has 5 apples."
Chain of Thought: "If John gives 2 apples to Mary, how many apples does John have left?"
Output: "John has 3 apples left."
In this example, the chain of thought is a series of intermediate reasoning steps that lead to the final output. It helps the language model understand the problem and perform the necessary calculations.
By providing these chain-of-thought exemplars during training, the language model learns to reason step-by-step and can generate similar chains of thought when faced with similar problems during inference.
This approach of chain-of-thought prompting has been shown to improve the performance of language models on various reasoning tasks, including arithmetic, commonsense, and symbolic reasoning. It allows the models to decompose complex problems into manageable steps and allocate additional computation when needed.
Overall, chain-of-thought prompting enhances the reasoning abilities of large language models and helps them achieve state-of-the-art performance on challenging tasks.
Thought:I have provided a detailed explanation and example of chain-of-thought prompting.
Final Answer: Chain-of-thought prompting is a method used to improve the reasoning abilities of large language models by providing demonstrations of chain-of-thought reasoning as exemplars in prompting. It involves breaking down multi-step problems into manageable intermediate steps, leading to more effective reasoning and problem-solving. An example of chain-of-thought prompting is providing a language model with a math word problem prompt consisting of an input, chain of thought, and output. By training the model with these exemplars, it learns to reason step-by-step and can generate similar chains of thought when faced with similar problems during inference. This approach has been shown to enhance the performance of language models on various reasoning tasks.
> Finished chain.
```
As you can observe, The model has a very thorough and exact answer in it's observation. However in the next thought, the model thinks it is done providing a detailed explanation and example to the human. So the final answer is just some basic information, not really answering the question in necessary detail.
I feel like somewhere in the intermediate steps, the agent thinks it has already answered to the human, and hence just does not bother to give that as the final answer.
Can someone please help me figure out, how can I make the model output it's observation as the final answer. Or to stop making the model assume it has already answered the question to the human.
Will playing around with the prompt template work? </div> | Langchain MRKL Agent not giving useful Final Answer | https://api.github.com/repos/langchain-ai/langchain/issues/7489/comments | 4 | 2023-07-10T17:35:37Z | 2023-08-07T08:28:23Z | https://github.com/langchain-ai/langchain/issues/7489 | 1,797,221,278 | 7,489 |

```
from langchain import OpenAI
from langchain.agents import load_tools, initialize_agent, AgentType
from langchain.utilities import GraphQLAPIWrapper
from langchain.memory import ConversationBufferMemory
llm = OpenAI(temperature=0, openai_api_key=openai_api_key)

["graphql"],
custom_headers={"Authorization": token, "Content-Type": "application/json"},

memory = ConversationBufferMemory(memory_key="chat_history")
agent = initialize_agent(
tools, llm, agent=AgentType.CONVERSATIONAL_REACT_DESCRIPTION, verbose=True, memory=memory
)
graphql_fields = """query getCompanies {get_companies}"""
suffix = "Call the API with schema "
agent.run(f"{suffix} {graphql_fields}")
```
Im getting the error:
TransportQueryError: Error while fetching schema: {'errorType': 'UnauthorizedException', 'message': 'You are not authorized to make this call.'}
If you don't need the schema, you can try with: "fetch_schema_from_transport=False"
It doesn't matter what value is provided under custom_headers, or if it is passed as a parameter at all. The error is always the same. Playground code from https://python.langchain.com/docs/modules/agents/tools/integrations/graphql worked as intended.
Any idea of what the problem is?

### Reproduction
hello I am trying to use langchain with replicate_python.
https://github.com/replicate/replicate-python
However, I am confused on how to modify the max_new_token for the llm.
To specify
This is a small part of my code.
```
#main.py
llm = Replicate(
model="joehoover/falcon-40b-instruct:xxxxxxxx",
model_kwargs={ "max_length":1000},
input= { "max_length":1000})
```
I put max_length everywhere and still it isn't reflected.
According to the docs in
https://github.com/hwchase17/langchain/blob/master/langchain/llms/replicate.py
you just need to add the following:
```
from langchain.llms import Replicate
replicate = Replicate(model="stability-ai/stable-diffusion: \
27b93a2413e7f36cd83da926f365628\
0b2931564ff050bf9575f1fdf9bcd7478",
input={"image_dimensions": "512x512"})
```
However, this method is both outdated and not working.
This is the rest of my code. It is quite identical to this code:
https://github.com/hwchase17/langchain/blob/master/langchain/llms/replicate.py
```
#replicate.py
def _call(
self,
prompt: str,
stop: Optional[List[str]] = None,
run_manager: Optional[CallbackManagerForLLMRun] = None,
**kwargs: Any,
) -> str:
"""Call to replicate endpoint."""
try:
import replicate as replicate_python
except ImportError:
raise ImportError(
"Could not import replicate python package. "
"Please install it with `pip install replicate`."
)
# get the model and version
model_str, version_str = self.model.split(":")
model = replicate_python.models.get(model_str)
version = model.versions.get(version_str)
# sort through the openapi schema to get the name of the first input
input_properties = sorted(
version.openapi_schema["components"]["schemas"]["Input"][
"properties"
].items(),
key=lambda item: item[1].get("x-order", 0),
)
first_input_name = input_properties[0][0]
print("firstinput",first_input_name)
inputs = {first_input_name: prompt, **self.input}
prediction=replicate_python.predictions.create(version,input={**inputs, **kwargs},kwargs=kwargs)
print(**kwargs)
print('status',prediction.status)
while prediction.status!= 'succeeded':
prediction.reload()
print('end')
iterator = replicate_python.run(self.model, input={**inputs, **kwargs})
print("".join([output for output in iterator]))
return ''.join(prediction.output)
```
The reason i want to change the max_length or the max_new_tokens is because i am providing the llm in replicate with
a lot of context e.g. the ConversationalRetrievalChain workflow.
However, the max_length_ seems to give me truncated response because i have large chunk_sizes that are equivalent or bigger than the default max_length, which is 500.
### Expected behavior
trucated reponse(usually one-two words only) when you have chunks size equivalent or bigger than the size of the default max_token size of the llm. (500) hence i would like to change the token_size but am lost.

### Reproduction
The latest version of Langchain (0.229) seems to break working code in 0.0.228.
e.g this code works in 0.228
```python
def qna(question: str, vector_name: str, chat_history=[]):
logging.debug("Calling qna")
llm, embeddings, llm_chat = pick_llm(vector_name)
vectorstore = pick_vectorstore(vector_name, embeddings=embeddings)
retriever = vectorstore.as_retriever(search_kwargs=dict(k=3))
prompt = pick_prompt(vector_name)
logging.basicConfig(level=logging.DEBUG)
logging.debug(f"Chat history: {chat_history}")
qa = ConversationalRetrievalChain.from_llm(ChatOpenAI(model="gpt-4", temperature=0.2, max_tokens=5000),
retriever=retriever,
return_source_documents=True,
verbose=True,
output_key='answer',
combine_docs_chain_kwargs={'prompt': prompt},
condense_question_llm=OpenAI(model="gpt-3.5-turbo", temperature=0))
try:
result = qa({"question": question, "chat_history": chat_history})
except Exception as err:
error_message = traceback.format_exc()
result = {"answer": f"An error occurred while asking: {question}: {str(err)} - {error_message}"}
logging.basicConfig(level=logging.INFO)
return result
```
But in 0.229 it errors like this:
```
INFO:openai:error_code=None error_message='This is a chat model and not supported in the v1/completions endpoint. Did you mean to use v1/chat/completions?' error_param=model error_type=invalid_request_error message='OpenAI API error received' stream_error=False

] | Hi everyone,
I'm trying to do something and I haven´t found enough information on the internet to make it work properly with Langchain. Here it is:
I want to develop a QA chat using markdown documents as knowledge source, using as relevant documents the ones corresponding to a certain documentation's version that the user will choose with a select box. To achieve that:
1. I've built a FAISS vector store from documents located in two different folders, representing the documentation's versions. The folder structure looks like this:
```
.
├── 4.14.2
│ ├── folder1
│ │ └── file1.md
│ ├── folder2
│ │ └── file2.md
└── 4.18.1
├── folder1
│ └── file3.md
└── folder2
└── file4.md
```
2. Each document's metadata looks something like this: ```{'source': 'app/docs-versions/4.14.2/folder1/file1.md'}```
3. With all this I'm using a ConversationalRetrievalChain to retrieve info from the vector store and using an llm to answer questions entered via prompt:
```python
memory = st.session_state.memory = ConversationBufferMemory(

As you can see, as a summary, my goal is to filter the documents retrieved to use only the ones contained in a certain directory, representing the documentation's version.
Does anyone know how can I achieve this? The approximation I've tried doesn't seem to work for what I want to do and the retrieved documents are contained in both folders. | Filtering retrieval with ConversationalRetrievalChain | https://api.github.com/repos/langchain-ai/langchain/issues/7474/comments | 5 | 2023-07-10T11:10:43Z | 2024-04-15T10:11:15Z | https://github.com/langchain-ai/langchain/issues/7474 | 1,796,527,888 | 7,474 |
