] | ### Checked other resources
- [X] I added a very descriptive title to this issue.
- [X] I searched the LangChain documentation with the integrated search.
- [X] I used the GitHub search to find a similar question and didn't find it.
- [X] I am sure that this is a bug in LangChain rather than my code.
### Example Code
```py
async def stream_tokens():
async for event in agent.astream_events(
{"input": prompt},
{"configurable": {"session_id": "some_hard_coded_value"}},
version="v1",
):
kind = event["event"]
if kind == "on_chat_model_stream":
content = event["data"]["chunk"].content
if content:
yield content
yield ""
```
```py
agent_with_history = RunnableWithMessageHistory(
agent,
lambda session_id: CassandraChatMessageHistory(
keyspace="some_hard_coded_value",
session=cluster.connect(),
session_id="some_hard_coded_value"
),

agent = AgentExecutor(

### Description
I'm trying to integrate chat history with Cassandra, like I did for chain. With astream_events on AgentExecutor I have problem that config isn't passed down, so it throws error like in traceback. I tried to manually edit source code at /Library/Caches/pypoetry/virtualenvs/backend-python-Nj9PzyUh-py3.11/lib/python3.11/site-packages/langchain_core/runnables/base.py line 4123, and add on my own to final config configurable["session_id"]. After that, it's working. I'm working with GPT-4, but this bug should appear no matter which LLM you are using.

### Description
When using Vertex AI's Gemini generative models, an exception called ResponseBlockedError is being raised when the generated text reaches either the maximum allowed token limit or a natural stopping point, as defined in the Google Vertex AI Python library (https://github.com/googleapis/python-aiplatform/blob/93036eda04566501e74916814e950236d9dbed62/vertexai/generative_models/_generative_models.py#L640-L644). However, instead of handling the error gracefully within Langchain, the exception is being propagated to the top level of the instance call, causing unexpected behavior and potentially interrupting workflows.

Snippet: Natixis conducted a systematic identification and materiality assessment of climate risk impacts.
This exercise leveraged existing Natixis risk mapping and relied on a qualitative analysis of the materiality
of impacts by Environmental and Social Responsibility and risk experts in the short medium term ( 5 years) and
long term (5.30 years). The analysis led to distinguish between indirect impactsresulting from Natixis
exposure to other entities (clientsassetsetc.) exposed to climate risksand direct impacts to which Natixis is
exposed through its own activities.
Source: conflicts.csv, Row: 14
Snippet: All risksincluding climate related risksare identified and evaluated at the regional level with the
help of regional experts. They cover the entire range of climate related issues (transitional and physical
issues). Risks are assessed on a gross risk basis. Gross risk is defined as risk without mitigation controls.
The risks are analyzed according to the criteria “EBIT effect� and “probability.�

it is returning multiple outputs from the same source, but i was expecting one output from each and every source document. Seems like multiple snippets from the same source should be combined and based out of that combined text it should return that one output for that source. Can you please look into this?

Answer:
Natixis conducts a systematic identification and materiality assessment of climate risk impacts through their
risk mapping process. This involves evaluating all risks, including climate related risks, at the regional
level with the help of regional experts. The risks are assessed on a gross risk basis, meaning without
mitigation controls, and are analyzed according to the criteria "EBIT effect" and "probability." This process
also distinguishes between indirect impacts resulting from Natixis' exposure to other entities and direct
impacts from their own activities.

### Example Code
This is how I get the Azure OpenAI LLM object
```python
def getLlmObject():
getToken()
model = AzureChatOpenAI(
openai_api_version=os.environ['OPENAI_API_VERSION'],
azure_deployment=os.environ['AZURE_OPENAI_DEPLOYMENT'],
azure_endpoint = os.environ['AZURE_ENDPOINT'],
openai_api_type = 'azure',
user = f'{{"appkey": "{APP_KEY}"}}'
)
return model
```
It would be ideal to change line 205 to detect non Streaming capability of the model or provide an option to set ```streaming=False``` during instantiation using ```AzureChatOpenAI``` class.

I have developed a program that allows for the uploading of multiple PDF files, and it includes a feature where you can specify a "vector count" for each PDF. This vector count determines how many similar snippets the program will identify and return from each uploaded PDF. For example, if the vector count is set to 5, the program will find and return 5 similar snippets from each PDF file. My question concerns how the program processes these snippets to answer queries for each PDF file: does it compile the top 5 similar snippets from each PDF, concatenate these snippets together, and then generate a response based on the combined content from each file? Or does it select the most relevant snippet from those top 5 and base its response solely on that single snippet? I just want to know how **RetrievalQA** works

### Description
# Confluence Project Issue
## Problem Description
I am working on a Confluence project where I have implemented an "include attachments=True" feature. The functionality works fine locally, and the code is deployed on two servers. However, on one of the servers, I am encountering a "Bad request" error. Despite having all the necessary dependencies installed, the issue persists.
## Dependency Information
Here are the dependencies installed on all servers:
- Django 4.0
- Django Rest Framework
- Langchain 0.1.1
- Markdownify
- Pillow
- Docx2txt
- Xlrd
- Pandas
- Reportlab
- Svglib
- Pdf2image
- Chromadb
- Unstructured
- OpenAI
- Pypdf
- Tiktoken
- Django-cors-headers
- Django-environ
- Pytesseract 0.3.10
- Beautifulsoup4 4.12.2
- Atlassian-python-api 3.41.9
- Lxml
- Langchain-community
- Langchain-openai
- Python-docx
- Unstructured-inference
- Unstructured[all-docs]
- Pydantic
- Langchainhub
## Additional Information
- The issue occurs specifically on one server.
- The "include attachments" feature is working fine on the local environment and another server.
- All dependencies are installed on the problematic server.
- The server where the issue occurs has Django 4.0 installed.
## Steps Taken
- Checked server logs for any specific error messages.
- Verified that all necessary dependencies are installed on the problematic server.
- Ensured that the codebase is the same across all servers.
## Error Message
On the problematic server, I am receiving a "Bad request" error.
## Request for Assistance
I would appreciate any guidance or suggestions on how to troubleshoot and resolve this issue. If anyone has encountered a similar problem or has insights into Confluence projects and attachment inclusion, your assistance would be invaluable.
Thank you!

- [X] I am a LangChain maintainer, or was asked directly by a LangChain maintainer to create an issue here.
### Issue Content
## Goal
Improve streaming in LangChain for chat models / language models.
## Background
Many chat and language models implement a streaming mode in which they stream tokens one at a time.
LangChain has a callback system that is useful for logging and important APIs like "stream", "stream_log" and "stream_events".
Currently many models incorrectly yield the token (chat generation) before invoking the callback.
## Acceptance criteria
For a PR to be accepted and merged, the PR should:
- [ ] Fix the code to make sure that the callback is called before the token is yielded
- [ ] Link to this issue
- [ ] Change ONE and only ONE model
- [ ] FIx sync and async implementation if both are defined
## Example PR
Here is an example PR that shows the fix for the OpenAI chat model:
https://github.com/langchain-ai/langchain/pull/16909
## Find models that need to be fixed
The easiest way to find places in the code that may need to be fixed is using git grep
```bash
git grep -C 5 "\.on_llm_new"
```
Examine the output to determine whether the callback is called before the token is yielded (correct) or after (needs to be fixed). | Callback for on_llm_new_token should be invoked before the token is yielded by the model | https://api.github.com/repos/langchain-ai/langchain/issues/16913/comments | 1 | 2024-02-02T00:39:51Z | 2024-06-27T20:09:31Z | https://github.com/langchain-ai/langchain/issues/16913 | 2,113,804,737 | 16,913 |

```
### Error Message and Stack Trace (if applicable)
_No response_
### Description
Bug: TextSplitter produces smaller chunks than specified with chunk_size, when instantiated `from_huggingface_tokenizer()`.
Explanation: `_merge_splits` counts `total` incorrectly when instantiated with `from_huggingface_tokenizer()`. BertTokenizer appends start and end tokens to any string it is ran on `['101', '102']`. It results in incorrect string length computation during splits merge, with total overestimating "real" chunk length. I.e. :
```python
>>>> self._length_function("")
2
```
therefore, here
```python
177: separator_len = self._length_function(separator)
...
183: _len = self._length_function(d)
...
210: total += _len + (separator_len if len(current_doc) > 1 else 0)
```
total is over counting the real chunk length, and stops the merge earlier than reaching the desired chunk_size. **This impacts resulting chunk sizes significantly when using very commonly occurring separators, i.e. whitespaces. See example.**
Suggested solution:
Replace all occurrences of `tokenizer.encode` for `tokenizer.tokenize` in [text_splitter.py](https://github.com/langchain-ai/langchain/blob/7d03d8f586f123e5059cbd0f45cb4c701bf0976f/libs/langchain/langchain/text_splitter.py#L702).
i.e.
```python
def _huggingface_tokenizer_length(text: str) -> int:
return len(tokenizer.encode(text)) # replace this line with return len(tokenizer.tokenize(text))
```

### Description
I am using RedisCache as per the docs [here](https://python.langchain.com/docs/integrations/llms/llm_caching#redis-cache)
Was testing how robust the system is if the redis connection fails for somereason or it goes out of memory.
Looks like if the redis connection URL is not reachable, the system throws an error.
I wanted langchain to internally handle redis failure and do a direct API calls to the LLM on failure. we can ofcourse log the error. This will make the system more robust to failures.
Does it make sense to add this feature? If so, I can help with raising a PR.

### Error Message and Stack Trace (if applicable)
This class lacks the page and per_page parameters, and I want to add these two parameters to implement pagination functionality.
### Description
The current implementation of GitHubIssuesLoader lacks pagination support, which can lead to inefficiencies when retrieving a large number of GitHub issues. This enhancement aims to introduce pagination functionality to the loader, allowing users to retrieve issues in smaller, manageable batches.
This improvement will involve adding page and per_page parameters to control the pagination of API requests, providing users with greater flexibility and performance optimization. Additionally, proper validation will be implemented to ensure valid and non-negative values for the pagination parameters.
This enhancement will enhance the usability and efficiency of the GitHubIssuesLoader class, making it more suitable for handling repositories with a substantial number of issues.

### Description
It looks like the `HuggingFaceHub` LLM sends `model_kwargs` with a wrong parameters name in the JSON payload. The correct name should be `parameters` instead of `params` according to the [HuggingFace API documentation](https://huggingface.co/docs/api-inference/en/detailed_parameters#text-generation-task).
https://github.com/langchain-ai/langchain/blob/2e5949b6f8bc340a992b9f9f9fb4751f87979e15/libs/community/langchain_community/llms/huggingface_hub.py#L133
As a result, `model_kwargs` has no effect on the model output as can be seen in the example above.

Step 1: Begin by verifying if the provided dataframe and instructions contain sufficient information for the required analysis. In case of insufficient details, respond with:
```json
{
"table": {},
"message": ["Please review and modify the prompt with more specifics."]
}
```
Step 2: Should the query necessitate generating a table, structure your response using the following format:
```json
{
"table": {
"columns": ["column1", "column2", ...],
"data": [[value1, value2, ...], [value1, value2, ...], ...]
},
"message": []
}
```
Step 3: For queries requiring solely a textual response, utilize the following format:
```json
{
"table": {},
"message": ["Your text response here"]
}
```
Step 4: Ensure consistent usage of standard decimal format without scientific notation. Replace any None/Null values with 0.0."

botocore.errorfactory.ValidationException: An error occurred (ValidationException) when calling the InvokeModelWithResponseStream operation: Malformed input request: string [
Observation] does not match pattern ^(\|+|User:)$, please reformat your input and try again.
### Description
The function 'create_react_agent' in langchain/agent/react/agent.py binds the stop sequence ["\nObservation"] to the runnable, making it incompatible with Bedrock's validation regex: ^(\|+|User:)$
When line 103 is changed from
```python
llm_with_stop = llm.bind(stop=["\nObservation"])
```
to
```python
llm_with_stop = llm.bind(stop=["User:"])
```
the call to invoke the model is successful as part of the agent executor chain because "User:" is one of the allowed stop sequences according to AWS. I think these limitations on the stop sequences allowed are a bit nonsensical, and this may be a bug with AWS itself. However, hard coding the stop sequence into the react agent constructor prevents this from being fixed without modifying the Langchain code.

### Error Message and Stack Trace (if applicable)
_No response_
### Description
I'm trying to use the get_openai_callback from langchain_community.callbacks to get the number of token and costs incurred in using the agent but I am getting zero on everything, as you can see here when I print.
I have also set up a custom callback handler to go deep into the issue and what I found is that ChatOpenAI from langchain_openai does not call ainvoke as ChatOpenAI langchain.chat_models did.
THank you for your help

### Example Code

from langchain.vectorstores.weaviate import Weaviate
from langchain.text_splitter import RecursiveCharacterTextSplitter
from langchain_community.document_loaders import TextLoader
import weaviate

from langchain.retrievers.weaviate_hybrid_search import WeaviateHybridSearchRetriever

chunk_overlap=20,
length_function=len))
weave.from_documents(documents=pages,client=client,embedding=None,index_name="people4",text_key="age",vectorizer="text2vec-transformers")
```
### Error Message and Stack Trace (if applicable)
TypeError: Weaviate.__init__() got an unexpected keyword argument 'vectorizer'
### Description
Weaviate allows users to mention a key value pair of vectorizer while creating a class so that users can leverage local vectorization or basically vectorization of their choice for each class.
Currently this is not implemented in langchain and only a default type schema gets created with a singular data property when using the from_documents or from_texts function calls.
Motivation:
I was using langchain weaviate modules as my library to manage my weaviate storage. But the main problem was that I wanted to use weaviate's local text2vec transformers but in langchain there was no way to pass this argument to make sure that particular documents are embedded with particular vectorizers.

### Error Message and Stack Trace (if applicable)
This piece of code doesn't have any errors
But in large-scale data retrieval, the absence of proxies may result in data scraping failures. Therefore, it is recommended to incorporate proxy functionality here to enhance engineering capabilities and efficiency
### Description
## Problem Overview:
The current PlaywrightEvaluator class lacks proxy support, limiting flexibility when processing pages using this class. To enhance functionality and improve the class's applicability, it is suggested to add proxy support within the class.
## Proposed Enhancement:
Modify the PlaywrightEvaluator class to accept proxy parameters, allowing the use of proxies when creating Playwright pages. This improvement would enable users to conveniently utilize proxies for accessing pages, thereby expanding the class's use cases.

I'm creating my Pinecone DB as documentation via Pinecone says and trying to upsert my langchain documents into Pinecone, however it is saying I haven't specified my API key which I clearly have. The index is created fine, but I'm hitting a brick wall trying to get my documents into it.
I'm using pinecone as my vector DB and help from langchain for a RAG application. The langchain documentation for Pinecone is outdated (using pinecone init which is not supported anymore) and I'm seeing other people online say they are getting this issue too ([https://www.reddit.com/r/LangChain/comments/199mklo/langchain_011_is_not_working_with_pineconeclient/](https://www.reddit.com/r/LangChain/comments/199mklo/langchain_011_is_not_working_with_pineconeclient/))

### Description
This new class presents a few problems.
- It is not sqlite compatible
- It uses a `connection_string` parameter, whereas `db_url` is used everywhere.
- It does not allow the call to be encapsulated in a transaction, as it cannot receive an engine parameter instead of `db_url`.
The usage with langchain is to propose an engine parameter to manipulate SQL.
Is the case for :
langchain_community.cache.SQLAlchemyCache
langchain_community.cache.SQLAlchemyMd5Cache

I have followed the documentations guide and create an agent with vector retriever with a Pydantic schema passed as function into the agent, but it seems that there is no information from. the retriever is passed to the schema function, the schema function will just give source [1] as output. I have also tried a exact replicate of the code in the documentation with my own data since I don't have the state_of_the_union text file and I got the same error as what I am getting in my own implementation
This is the documentation link https://python.langchain.com/docs/modules/agents/how_to/agent_structured
during my experiments

You can see that this piece of information containing capstone =. 5.5 is at page chuck 10

In the response to what is my capstone grade, it gives source [] which is definitely not the right information
### Idea or request for content:
I am not too exactly sure about what is causing the problem, maybe I should flag this as a bug or maybe just some configuration error.
My suspicion is that after the creation of the retriever tool, it formats the document using a prompt which strip away the meta data information. I have tried passing an additional prompt when im creating the retriever tool so that it returns the meta data output together with the content.

But it takes a lot of luck and tuning to get the final answer to get the correct source information (have succeeded before once in a while but not most of the time)

### Description
I wanted to make the LLM passed to a runnable a configurable parameters (makes sense semantically in my application). It fails with the error above. Interestingly, if I instead invoke the runnable with a config dict it works:
```
test = MyRunnable().invoke({}, config={"configurable": {"llm": llm}})
```
I looked a little into it, the exact reason still eludes me but it seems like for some reason, when `with_config` is called, the passed parameters are validated by Pydantic *which tries to instantiate them in order to do so*, which fails since the `llm` attribute is annotated with an ABC that cannot be directly instantiated.
This is likely related to https://github.com/langchain-ai/langchain/issues/2636 .

I tried out the tutorial at this link: https://python.langchain.com/docs/modules/model_io/output_parsers/types/retry
But I getting this error related to Retry Parser tutorial example `ValidationError: 1 validation error for Action action_input Field required [type=missing, input_value={'action': 'search'}, input_type=dict] For further information visit https://errors.pydantic.dev/2.5/v/missing`.
After conducting various experiments to find the cause, I found out that changing the part `from pydantic import BaseModel, Field` in the code example to `from langchain_core.pydantic_v1 import BaseModel, Field` makes the example code run correctly. The version of langchain I tested is `0.1.3.`
It seems that the official documentation's examples have not been updated to reflect the changes in syntax due to version updates of langchain, so I'm leaving this issue.
#### 👉 Summary
- I tried out the Retry Parser tutorial example
- I founded an error that seems to be due to the example content not being updated following a version update of langchain.
- from `from pydantic import BaseModel, Field`
- to `from langchain_core.pydantic_v1 import BaseModel, Field`
- I used to `langchain v0.1.3` and I confirmed that the example works correctly when executed as I described.

- [X] I added a very descriptive title to this issue.

- [X] I used the GitHub search to find a similar question and didn't find it.
- [X] I am sure that this is a bug in LangChain rather than my code.
### Example Code
```python
from langchain.vectorstores.weaviate import Weaviate
from langchain.text_splitter import RecursiveCharacterTextSplitter
from langchain_community.document_loaders import TextLoader
import weaviate
client = weaviate.Client(url="http://localhost:8080")
weave = Weaviate(client=client,index_name="people",text_key="age")
file = TextLoader("file.txt",encoding="utf-8")
pages = file.load_and_split(text_splitter=RecursiveCharacterTextSplitter(chunk_size=100,
chunk_overlap=20,
length_function=len))
weave.from_documents(documents=pages,client=client,embedding=None,index_name="people",text_key="age")
props = client.schema.get(class_name="people")['properties']
for prop in props:
print(prop['name'])
```
### Error Message and Stack Trace (if applicable)
No error but a discrepancy due to lack of argument passing in the function call
### Description
* I am trying to use the weaviate vectorstore in langchain to store documents
* When using the **from_documents** function which internally calls **from_texts** there is a mismatch in the expected properties of the schema/class created.
* In the **from_texts** call there is a **_default_schema** function that is called without passing the **text_key**, because of which an additional property named "key" gets created which is not needed.
Example:
When i create a class with **from_documents** with a **text_key** let's say "age". The properties of the class should have only age and source as it's keys and not age,source and text.
**Solution: Pass the text_key inside the _default_schema function and create a class accordingly**

### Description
When I use knowledge bases directly with Boto3 client it works. This makes me suspect error is coming from or callbackManager, but I don't know why that would be used?
for result in results:
documents.append(
Document(
page_content=result["content"]["text"],
metadata={
"location": result["location"],
"score": result["score"] if "score" in result else 0,
},
)
)

### Example Code
Doesn't matter, only matters that you are using the latest stable LangChain and LangChain OpenAI packages. For example
```python
# testing.py
from langchain.prompts import PromptTemplate
from langchain.chains import LLMChain
from langchain_openai import ChatOpenAI
# Assuming OPENAI_API_KEY is set, which it is on my system
llm = ChatOpenAI(model_name="gpt-3.5-turbo")
sentiment = PromptTemplate(
input_variables=["text"],
template="Analyse the sentiment of the following text. Please choose an answer from (negative/neutral/positive). Text: {text}"
)
analyze_sentiment = LLMChain(llm=llm, prompt=sentiment, verbose=True)
if __name__=="__main__":
print(analyze_sentiment.run(text="I am very frustrated right now"))
```
For good measure, I ran the following cURL command from the [OpenAI Docs](https://platform.openai.com/docs/api-reference/chat/create).
```bash
curl https://api.openai.com/v1/chat/completions \
-H "Content-Type: application/json" \
-H "Authorization: Bearer $OPENAI_API_KEY" \
-d '{
"model": "gpt-3.5-turbo",
"messages": [
{
"role": "system",
"content": "You are a helpful assistant."
},
{
"role": "user",
"content": "Hello!"
}
]
}'
```
Which worked fine.
### Error Message and Stack Trace (if applicable)
Here is the Python output.
```bash

### Description
I'm confused as this is a freshly installed project, fresh API key, and I've been using LangChain just fine in other projects all day, and only happens in the latest version. It also happens with the deprecated `langchain.chat_models.ChatOpenAI` and `langchain_community.chat_models.ChatOpenAI`, but not in my other projects with older LangChain versions.

### Issue Content
There are a lot of questions on how to use RunnableWithMessageHistory.
We need to improve this page:
https://python.langchain.com/docs/expression_language/how_to/message_history
This page should be updated to include the following information (in approximately this order):
- [ ] Example that uses in memory or on file system chat history to make it easier to test things out and debug
- [ ] Example that shows how to use the config to support user_id in addition to session_id (just passing through config)
- [ ] Clarifications that in production one should use persistent storage (e.g., Redis)
- [ ] Show how to use Redis persistent storage
There is an API reference here:
https://api.python.langchain.com/en/latest/runnables/langchain_core.runnables.history.RunnableWithMessageHistory.html
Example with file system here:
https://github.com/langchain-ai/langserve/blob/main/examples/chat_with_persistence_and_user/server.py
Here are some questions, some of which have answers:
* https://github.com/langchain-ai/langchain/discussions/16582

### Error Message and Stack Trace (if applicable)
_No response_
### Description
I've encountered cases where my langchain runs were not traced with Comet tracer even when enabled. I was able to reproduce with the first minimal reproducing script.
To reproduce the issue, runs into an environment without `comet_ml` nor `wandb` being installed. If you run it as is, the script will runs just fine and won't try to log the LLM generation to Comet or Wandb. If you uncomment the import to `langchain_community.callbacks`, it will now fails with:
```
Traceback (most recent call last):

raise ImportError(
ImportError: To use the CometTracer you need to have the `comet_llm>=2.0.0` python package installed. Please install it with `pip install -U comet_llm`
```
It also happens with Wandb tracer. If you uncomment the line containing `LANGCHAIN_WANDB_TRACING` and run it, you should see the following error:
```
Traceback (most recent call last):

The above exception was the direct cause of the following exception:

raise ImportError(
ImportError: Could not import wandb python package.Please install it with `pip install -U wandb`.
```
I've tried a more advanced example using a chain (second reproduction script) and it always fails.
I'm not sure if it's a bug or not. This was definitely surprising for me as I was expected to get my langchain runs with the first shared script. If it's not a bug, it think it would be useful to clarify when users can expect community tracers to be injected and when they wouldn't.
Let me know what you think about this issue and how can I help.

I expected to be able to pass an object annotated with a Pydantic model (Pydantic is used elsewhere in langchain for annotating input/output types), but when I try to get the input schema for the resulting chain, I get the above error.

### Description
When using the `VertexAIModelGarden` class to send requests to fine-tuned models on Vertex AI, the class is designed to target endpoints rather than directly to a model. However, for my use case, I need to send requests directly to a fine-tuned model URL. The current implementation seems to only allow sending requests to an endpoint, which does not fit the requirement.
### Steps to Reproduce
1. Instantiate the `VertexAIModelGarden` class with the project ID and endpoint ID.
2. Use the `predict` method to send a prompt to the model.
3. The request is sent to an endpoint URL rather than the fine-tuned model URL.
### Expected Behavior
I expect to be able to specify a fine-tuned model URL directly, similar to how it's done using the `TextGenerationModel` class from the `vertexai` package:
```python
import vertexai
from vertexai.language_models import TextGenerationModel
vertexai.init(project="my-project-id", location="my-location")
model = TextGenerationModel.from_pretrained("base-model-name")
model = model.get_tuned_model("projects/my-project-id/locations/my-location/models/my-model-id")
response = model.predict(prompt, **parameters)

text1 = """Outokumpu Annual report 2019 | Sustainability review 23 / 24 • For business travel: by estimated driven kilometers with emissions factors for the car, and for flights by CO2 eq. reports of the flight companies. Rental car emissions are included by the rental car company report. Upstream transport was assessed on data of environmental product declaration of 2019 but excluded from scope 3 emissions. The recycled content is calculated as the sum of pre and post consumer scrap related to crude steel production. Additionally, we report on the recycled content including all recycled metals from own treated waste streams entering the melt shop. Energy efficiency is defined as the sum of specific fuel and electricity energy of all processes calculated as energy consumption compared to the product output of that process. It covers all company productions: ferrochrome, melt shop, hot rolling and cold rolling processes. Used heat values and the consumption of energy are taken from supplier's invoices. Water withdrawal is measured for surface water, taken from municipal suppliers and estimated for rainwater amount. Waste is separately reported for mining and stainless production. In mining, amount of non-hazardous tailing sands is reported. For stainless production hazardous and non-hazardous wastes are reported as recycled, recovered and landfilled. Waste treated is counted as landfilled waste. Social responsibility Health and safety figures Health and safety figures reflect the scope of Outokumpu’s operations as they were in 2019. Safety indicators (accidents and preventive safety actions) are expressed per million hours worked (frequency). Safety indicators include Outokumpu employees, persons employed by a third party (contractor) or visitor accidents and preventive safety actions. A workplace accident is the direct result of a work-related activity and it has taken place during working hours at the workplace. Accident types • Lost time injury (LTI) is an accident that caused at least one day of sick leave (excluding the day of the injury or accident), as the World Steel Association defines it. One day of sick leave means that the injured person has not been able to return to work on their next scheduled period of working or any future working day if caused by an outcome of the original accident. Lost-day rate is defined as more than one calendar day absence from the day after the accident per million working hours. • Restricted work injury (RWI) does not cause the individual to be absent, but results in that person being restricted in their capabilities so that they are unable to undertake their normal duties. • Medically treated injury (MTI) has to be treated by a medical professional (doctor or nurse). • First aid treated injury (FTI), where the injury did not require medical care and was treated by a person himself/herself or by first aid trained colleague. • Total recordable injury (TRI) includes fatalities, LTIs, RWIs and MTIs, but FTIs are excluded. • All workplace accidents include total recordable injuries (TRI) and first aid treated injuries (FTI) Proactive safety actions Hazards refer to events, situations or actions that could have led to an accident, but where no injury occurred. Safety behavior observations (SBOs) are safety-based discussions between an observer and the person being observed. Other preventive safety action includes proactive measures. Sick-leave hours and absentee rate Sick-leave hours reported are total sick leave hours during a reporting period. Reporting units provide data on absence due to illness, injury and occupational diseases on a monthly basis. The absentee rate (%) includes the actual absentee hours lost expressed as a percentage of total hours scheduled. Total personnel costs This figure includes wages, salaries, bonuses, social costs or other personnel expenses, as well as fringe benefits paid and/ or accrued during the reporting period. Training costs Training costs include external training-related expenses such as participation fees. Wages, salaries and daily allowances for participants in training activities are not included, but the salaries of internal trainers are included. Training days per employee The number of days spent by an employee in training when each training day is counted as lasting eight hours. Bonuses A bonus is an additional payment for good performance. These figures are reported without social costs or fringe benefits. Personnel figures Rates are calculated using the total employee numbers at the end of the reporting period. The calculations follow the requirements of GRI Standards. The following calculation has been applied e.g. Hiring rate = New Hires / total number of permanent employees by year-end Average turnover rate = (Turnover + New Hires) / (total number of permanent employees by year-end × 2) Days lost due to strikes The number of days lost due to strikes is calculated by multiplying the number of Outokumpu employees who have been on strike by the number of scheduled working days lost. The day on which a strike starts is included. n Scope of the report"""

### Error Message and Stack Trace (if applicable)
_No response_
### Description
I'm trying to use `RecursiveCharacterTextSplitter` with `add_start_index=True` but I found out some texts where the `start_index` is wrong. For example:
- given the `text1` in the code, the 6th passage has (4412, 4418) but it's overlapped with the 5th passage that has (4088, 5111)... this is wrong
- if I simply add a char in the `text1` str (i.e. `text2`), now the 6th passage has (5112, 5119) and it's correct

### Description
I noticed a discrepancy in the code comments where the parameter name is mentioned as model_name, but the actual parameter name in the code is model_id. This PR corrects the code comment to accurately reflect the parameter name used in the code. The corrected code snippet is as follows:
```python
from langchain_community.embeddings import SelfHostedHuggingFaceEmbeddings
import runhouse as rh
model_id = "sentence-transformers/all-mpnet-base-v2"
gpu = rh.cluster(name="rh-a10x", instance_type="A100:1")
hf = SelfHostedHuggingFaceEmbeddings(model_id=model_id, hardware=gpu)
```
source code
```python
class SelfHostedHuggingFaceEmbeddings(SelfHostedEmbeddings):
"""HuggingFace embedding models on self-hosted remote hardware.
Supported hardware includes auto-launched instances on AWS, GCP, Azure,
and Lambda, as well as servers specified
by IP address and SSH credentials (such as on-prem, or another cloud
like Paperspace, Coreweave, etc.).
To use, you should have the ``runhouse`` python package installed.
Example:
.. code-block:: python
from langchain_community.embeddings import SelfHostedHuggingFaceEmbeddings
import runhouse as rh
model_name = "sentence-transformers/all-mpnet-base-v2"
gpu = rh.cluster(name="rh-a10x", instance_type="A100:1")
hf = SelfHostedHuggingFaceEmbeddings(model_name=model_name, hardware=gpu)
"""

model_id: str = DEFAULT_MODEL_NAME
"""Model name to use."""
model_reqs: List[str] = ["./", "sentence_transformers", "torch"]
"""Requirements to install on hardware to inference the model."""
hardware: Any
"""Remote hardware to send the inference function to."""
model_load_fn: Callable = load_embedding_model
"""Function to load the model remotely on the server."""
load_fn_kwargs: Optional[dict] = None
"""Keyword arguments to pass to the model load function."""
inference_fn: Callable = _embed_documents
"""Inference function to extract the embeddings."""
```
This code indicates that the parameter should be `model_id` instead of `model_name`.
I'm willing to fix it by submitting a pull request. Would that be helpful, and should I proceed with preparing the PR?

I'm trying out this tutorial: https://python.langchain.com/docs/modules/model_io/prompts/example_selector_types/similarity
But I'm getting this error related to the Chroma vector store:
`vectorstore
instance of VectorStore expected (type=type_error.arbitrary_type; expected_arbitrary_type=VectorStore)`
What is the correct way to do this?
I already tried:
- changing the import to `from langchain_community.vectorstores.chroma import Chroma`
- changing the import to `from langchain_community.vectorstores import chroma`
- trying out different versions of lanchain-community (0.0.15, 0.0.14, 0.0.13)

] | ## Feature request
I'd like the option to pass the OpenAI api key to the `openai.Openai` client at runtime.
- ConfigurableField ([docs](https://python.langchain.com/docs/expression_language/how_to/configure)) already supports passing this variable to the client, and in fact allows me to change any config except `openai_api_key`.
- I suspect the original intent may have been to make it configurable: if `openai_api_key` is defined with a `configurable_field` there is no warning or Exception raised.
I can submit a PR; I'm already using the proposed change in my code.
## Motivation
There are many scenarios where I'd like to change the API key depending on the task I'm performing. This is especially true when using Langchain in the context of a microservice or API with a high volume of requests: building "cloned" modules or re-initializing modules is impractical.
## Your contribution
I can submit a PR in short order but am soliciting input here first.
The proposed change is to the validation function found here [(source)](https://github.com/langchain-ai/langchain/blob/2b2285dac0d6ae0f6b7c09c33882a0d5be26c078/libs/partners/openai/langchain_openai/chat_models/base.py#L344):
*Proposed change at the bottom*
```python
@root_validator()
def validate_environment(cls, values: Dict) -> Dict:
"""Validate that api key and python package exists in environment."""
if values["n"] < 1:
raise ValueError("n must be at least 1.")
if values["n"] > 1 and values["streaming"]:
raise ValueError("n must be 1 when streaming.")
values["openai_api_key"] = get_from_dict_or_env(
values, "openai_api_key", "OPENAI_API_KEY"
)
# Check OPENAI_ORGANIZATION for backwards compatibility.
values["openai_organization"] = (
values["openai_organization"]
or os.getenv("OPENAI_ORG_ID")
or os.getenv("OPENAI_ORGANIZATION")
)
values["openai_api_base"] = values["openai_api_base"] or os.getenv(
"OPENAI_API_BASE"
)
values["openai_proxy"] = get_from_dict_or_env(
values,
"openai_proxy",
"OPENAI_PROXY",
default="",
)
client_params = {
"api_key": values["openai_api_key"],
"organization": values["openai_organization"],
"base_url": values["openai_api_base"],
"timeout": values["request_timeout"],
"max_retries": values["max_retries"],
"default_headers": values["default_headers"],
"default_query": values["default_query"],
"http_client": values["http_client"],
}
##### PROPOSAL: REMOVE MARKED IF STATEMENTS FROM THIS CODE #####
if not values.get("client"): # <--- REMOVE
values["client"] = openai.OpenAI(**client_params).chat.completions
if not values.get("async_client"): # <--- REMOVE
values["async_client"] = openai.AsyncOpenAI(
**client_params
).chat.completions
##### END PROPOSAL #####
```
This would require no change in user behavior (putting OPENAI_API_KEY in the environment variables still works).
I'm not sure why these IF checks are here. If they're necessary to avoid re-defining `openai.OpenAI`, I'd suggest the benefit of a dynamic api key outweighs the cost of re-instantiation (and could be solved regardless by a quick check on whether the client_params changed).

### Example Code
The following code :
```python
from langchain_community.vectorstores.chroma import Chroma
from langchain_community.embeddings.openai import OpenAIEmbeddings
from dotenv import load_dotenv
load_dotenv()
DBPATH = './tmpdir/'
print("[current db status]")

persist_directory=DBPATH)
chroma2 = Chroma(collection_name='tmp2',
embedding_function=OpenAIEmbeddings(),
persist_directory=DBPATH)
print("tmp1 : ", chroma1.get()['documents'])
print("tmp2 : ", chroma2.get()['documents'])
print("[add texts]")
chroma1 = Chroma.from_texts(texts=['aaaaa', 'bbbbb'],
collection_name='tmp1',
embedding=OpenAIEmbeddings(),
persist_directory=DBPATH)
chroma2 = Chroma.from_texts(texts=['11111', '22222'],
collection_name='tmp2',
embedding=OpenAIEmbeddings(),
persist_directory=DBPATH)
chroma1.persist()
chroma2.persist()
print("tmp1 : ", chroma1.get()['documents'])
print("tmp2 : ", chroma2.get()['documents'])
print("[reload db]")
chroma1 = None
chroma2 = None
chroma1 = Chroma(collection_name='tmp1',

chroma2 = Chroma(collection_name='tmp2',
embedding_function=OpenAIEmbeddings(),
persist_directory=DBPATH)
print("tmp1 : ", chroma1.get()['documents'])
print("tmp2 : ", chroma2.get()['documents'])
```
### What I am doing :
I want to make multiple collections in same single persistent directory.
### What is currently happening :
Running the following code gives this output :
```bash
[current db status]
tmp1 : []
tmp2 : []
[add texts]
tmp1 : ['aaaaa', 'bbbbb']
tmp2 : ['11111', '22222']
[reload db]
tmp1 : []
tmp2 : ['11111', '22222']
```
### What I expect :
I expect that the results below [reload db] should be same as results below [add texts].
But tmp1 collection has no texts saved after I init chromadb client object like this `chroma2=None`.
As you can see printed result.
I am not getting why this is happening.
Any help would be much appreciated.

### Example Code
To reproduce, simply open a dev container [here](https://github.com/langchain-ai/langchain/tree/master/.devcontainer#vs-code-dev-containers).
### Two problems:
1. Dependency azure-ai-vision [has been yanked ](https://pypi.org/project/azure-ai-vision/) from Pypi and replaced by [another MS package](replaced by https://pypi.org/project/azure-ai-vision-imageanalysis/1.0.0b1/). This change is not reflected in `pyproject.toml`.
2. Upon updating the package reference, Poetry dependency resolution takes hours before it ultimately crashes.
### Error Message and Stack Trace (if applicable)
### The first problem is here:

---> [17](vscode-notebook-cell:?execution_count=33&line=17) spam.invoke("bar")
TypeError: BaseRetriever.invoke() got an unexpected keyword argument 'spam'
### Description
# Details
`.bind()` does not seem to be working well with `Retrievers`.
The `BaseRetriever.invoke()` does not support variadics arguments. Runtime binding on a retriever raises a `TypeError`.
A possible workaround is to use a `RunnableLambda` wrapping the `retriever.get_relevant_documents` and dispatching the bounded arguments to a `get_relevant_documents. `.
# How to reproduce
Instantiate a `CustomRetriever` as per [Langchain's documentation](https://python.langchain.com/docs/modules/data_connection/retrievers/) and `bind` an argument to it.
# What to expect
`bind` should dispatch bounded argument to `retrievers` too.

f"Expected annotation of 'Type[BaseModel]'"

f"Expected class looks like:\n"
f"{typehint_mandate}"
)
```
### Error Message and Stack Trace (if applicable)
_No response_
### Description
This code first checks if args_schema_type is not None, and then immediately checks if it is None, which doesn't make logical sense.
It should be:
```
if args_schema_type is not None and args_schema_type == BaseModel:
```
Also, perhaps the TODO should have an issue associated with it, though I'm not sure I have enough context to create the issue.

This is why `BaseChatMemory.chat_memory` doesn't pruning https://github.com/langchain-ai/langchain/issues/14957#issuecomment-1907951114

### Example Code
Attempting to initialize PineconeConnected
```

from langchain.embeddings.openai import OpenAIEmbeddings
from langchain.vectorstores import Pinecone
from langchain.schema import Document
class PineconeConnected():
def __init__(self, index_name: str, pinecone_api_key: str, pinecone_env: str, openai_key: str):

self.vector_db = Pinecone.from_existing_index(index_name, embeddings) # VectorStore object with the reference + Pinecone index loaded
def query(query:str, book_title=None)

### Description
when initializing PineconeConnected class, I get this error:
*Please note that this was previously working. pinecone-client updated its library a few days ago hence why this integration with 'init' no longer works.
```
AttributeError: init is no longer a top-level attribute of the pinecone package.
Please create an instance of the Pinecone class instead.
Example:
import os
from pinecone import Pinecone, ServerlessSpec
pc = Pinecone(
api_key=os.environ.get("PINECONE_API_KEY")
)
# Now do stuff
if 'my_index' not in pc.list_indexes().names():

### Idea or request for content:
I think it's a problem with the last input with agent, it expects str, but I don't know. | DOC: <Problem with imput in agent: ' prefix> | https://api.github.com/repos/langchain-ai/langchain/issues/16511/comments | 9 | 2024-01-24T12:51:58Z | 2024-05-01T16:07:19Z | https://github.com/langchain-ai/langchain/issues/16511 | 2,098,204,503 | 16,511 |

### Example Code
The following code: https://github.com/langchain-ai/langchain/blob/master/libs/community/langchain_community/retrievers/google_vertex_ai_search.py
Gives the error 'MethodNotImplemented: 501 Received http2 header with status: 404'
### Description
I'm trying to use the Google Vertex AI Wrapper.
I expect to get results from my datastore.
But got the error 'MethodNotImplemented: 501 Received http2 header with status: 404'.
The 'content_search_spec' parameter creates the problem as it's not seen in the API call.
Will be glad to share the working version.

### Example Code
I created two different indexes using
```
def create_index(node_label, index, text_properties):
existing_graph = Neo4jVector.from_existing_graph(
embedding=embedding_model,
url=url,
username='neo4j',
password=password,
index_name=index,
node_label=node_label,
text_node_properties=text_properties,
embedding_node_property=f"embedding",
)
create_index('Chunk','ockham',['document','text'])
create_index('Embed','tr10', ["text", "number"])
```
I then tried to return the tr10 index using:
```
def neo4j_index(index_name):
"""Use langchain to return the neo4j index"""
index = Neo4jVector.from_existing_index(
embedding=embedding_model(),
url=NEO4J_URI,
username=NEO4J_USER,
password=NEO4J_PASS,
index_name=index_name,
)
return index
index = neo4j_index('tr10')
```
But instead returned the 'ockham' index.
This was fixed by changing my function that created the index to specify different embedding property names.
```
def create_index(node_label, index, text_properties):
existing_graph = Neo4jVector.from_existing_graph(
embedding=embedding_model,
url=url,
username='neo4j',
password=password,
index_name=index,
node_label=node_label,
text_node_properties=text_properties,
embedding_node_property=f"embedding_{index}",
)

请问如何将create_extraction_chain作为SequentialChain中的子链来运行。
