- [X] I added a very descriptive title to this issue.
- [X] I included a link to the documentation page I am referring to (if applicable).
### Issue with current documentation:
1.New partner library of [langchain_huggingface](https://huggingface.co/blog/langchain) was released recently but the corresponding documentation on langchain is not updated https://python.langchain.com/v0.1/docs/integrations/chat/huggingface/
2.Classdocs are not updated. Example HuggingFaceEndpoint class doc says you should have installed the huggingface_hub package when infact only langchain_huggingface is enough.
### Idea or request for content:
The current langchain tutorial docs be updated to show the use of new library.
The library's classes' docs be updated. | DOC: <Langchain docs and library classdocs not updated after migration to the new langchain_huggingface library> | https://api.github.com/repos/langchain-ai/langchain/issues/21916/comments | 0 | 2024-05-20T13:51:13Z | 2024-05-20T13:53:35Z | https://github.com/langchain-ai/langchain/issues/21916 | 2,306,051,011 | 21,916 |

Final Answer: Bitcoin is a decentralized digital currency that allows for peer-to-peer transactions without the need for intermediaries. It was created in 2009 by an individual or group of individuals using the pseudonym Satoshi Nakamoto. Bitcoin operates on a decentralized network of computers that verify and record transactions, known as a blockchain. The blockchain is maintained by a network of nodes that work together to validate transactions and ensure the integrity of the network. Bitcoin is often referred to as a cryptocurrency, but it is also considered a form of digital gold, as it is a store of value and a medium of exchange. Bitcoin has gained popularity in recent years due to its potential for fast and secure transactions, as well as its potential for high returns on investment. However, it has also faced criticism and controversy due to its volatility and potential for use in illegal activities. Despite these challenges, Bitcoin remains a popular and widely used digital currency.

### Description
I'm trying to launch Devcontainer with .devcontainer provided in repository using VSCode. Launch failes during poetry install with message `Directory ../partners/openai does not exist`. This was a fresh clone from repository. No changes were introduced.
### System Info

- [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.

### Description
Calls to Ollama embeddings API are very slow (1000 to 2000ms) . GPU utilization is very low. Utilization spikes 30% - 100% once every second or two. This happens if I run main() or testOllamaSpeed() In the example code. This would suggest the problem is with Ollama. But If I run the following code which does not use any langchain imports each call completes in 200-300ms and GPU utilization hovers at a consistent 70-80%. The problem is even more pronounced if I use mxbai-embed-large with the example code taking 1000 to 2000ms per call and the code below taking ~50ms per call. VRAM usage is never above 4ish GB (~25% of my total VRAM).

I encountered a `**ValueError**` when trying to create an SQL agent using LangChain. The error message indicated that the prompt was missing required variables: `agent_scratchpad`, `tool_names`, and `tools`. Despite consulting various resources including Medium blogs, YouTube videos, GitHub references, and the LangChain documentation, I have not been able to find a solution.

OpenAI supports returning the token count while streaming: https://community.openai.com/t/usage-stats-now-available-when-using-streaming-with-the-chat-completions-api-or-completions-api/738156
However, this does not seem to work when using Langchain. It only seems to return 0's for agent_executor.astream_events.
This makes it very difficult to get the exact token counts for my agent. Are there any solutions?

RuntimeError: The expanded size of the tensor (614) must match the existing size (512) at non-singleton dimension 1. Target sizes: [20, 614]. Tensor sizes: [1, 512]
### Description
Hi,
I am using HuggingFaceCrossEncoder to rerank my retriever results for RAG. Generally it works but for some retrieval results I am getting the described error message. I checked the issue and assume that my input is too long as the max_tokens of the model "cross-encoder/msmarco-MiniLM-L12-en-de-v1" is 512.
Therefore I want to truncate the input in order to make it work, but found no solution when reading the docs.
Is this possible to do? Otherwise I have to stick to ColBERT for Reranking, there I don't see this issue.

] | ### 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.
- [X] The bug is not resolved by updating to the latest stable version of LangChain (or the specific integration package).
### Example Code
```python
from langchain_text_splitters import CharacterTextSplitter
from langchain_community.embeddings.fastembed import FastEmbedEmbeddings
from langchain_community.document_loaders import PyMuPDFLoader
from langchain_community.vectorstores import Clickhouse, ClickhouseSettings
file = "some_file.pdf"
loader = PyMuPDFLoader(file)
documents = loader.load()
text_splitter = CharacterTextSplitter(chunk_size=1000, chunk_overlap=0)
docs = text_splitter.split_documents(documents)
embeddings = FastEmbedEmbeddings()
settings = ClickhouseSettings(table="some_table")
docsearch = Clickhouse.from_documents(docs, embeddings, config=settings)
```
I am using clickhouse suggested in the docks
`! docker run -d -p 8123:8123 -p 9005:9000 --name langchain-clickhouse-server --ulimit nofile=262144:262144 clickhouse/clickhouse-server:23.4.2.11`

### Description
I'm trying to use the langchain SQLAlchemyCache with Postgres.
It doesn't work because it is trying to insert some big thing into an index that wants a small thing.

### Example Code

### if i use retriever with LLM chain like below. The filter condition is not working.
rag_chain = (
{"context": retriever | format_docs, "question": RunnablePassthrough()}
| custom_rag_prompt
| llm
| StrOutputParser()
)
rag_chain.invoke(standalone_question)
###In below code the filter condition is working.

query=standalone_question,
k=3,
search_type="similarity",
filters="Header2 eq '" + header_tag + "'",
)
display(docs_retr)
```
### Error Message and Stack Trace (if applicable)
_No response_
### Description
from the below file, under "_get_relevant_documents", while retrieving the documents we are not sending the filter condition from retriever rather the "_get_relevant_documents" expects the filter condition as kwargs. This is not possible while using the retriever with LLM chain which has memory.
https://github.com/langchain-ai/langchain/blob/master/libs/community/langchain_community/vectorstores/azuresearch.py
Existing code:
docs = self.vectorstore.hybrid_search(query, k=self.k, **kwargs)
New code suggested:
docs = self.vectorstore.hybrid_search(query, k=self.k, **self.search_kwargs)
Please update the code for all the search type.

### Error Message and Stack Trace (if applicable)
This is not an error, but rather the actual behavior.
As shown on the referenced page -> [Tracking token usage](https://python.langchain.com/v0.1/docs/modules/model_io/chat/token_usage_tracking/).
```
Tokens Used: 0
Prompt Tokens: 0
Completion Tokens: 0
Successful Requests: 2
Total Cost (USD): $0.0
```
### Description
Description:
I encountered an issue with the get_bedrock_anthropic_callback function in Langchain. According to the [documentation](https://python.langchain.com/v0.2/docs/how_to/chat_token_usage_tracking/#openai), the function should provide token usage details, but it returns all token values as 0.
Steps to Reproduce:
Use get_bedrock_anthropic_callback as described in the documentation.
Observe that token values are returned as 0.
Expected Behavior:
The function should return the correct token usage values.
Actual Behavior:
The function returns all token values as 0.
Considering the use of Claude 3 Opus, it would be beneficial to include Opus (anthropic.claude-3-opus-20240229-v1:0) in the model cost mapping. Here are the current values for reference:
langchain_community.callbacks.bedrock_anthropic_callback
``` python
MODEL_COST_PER_1K_INPUT_TOKENS = {
"anthropic.claude-instant-v1": 0.0008,
"anthropic.claude-v2": 0.008,

### Example Code
from langchain_openai import ChatOpenAI
### Error Message and Stack Trace (if applicable)
The problem is ~80 seconds of extreme CPU ramping lag, not an error message.
### Description
An incorrect message may be printed to terminal:
"langchain_core/_api/deprecation.py:119: LangChainDeprecationWarning:
The class `ChatOpenAI` was deprecated in LangChain 0.0.10 and will be
removed in 0.3.0. An updated version of the class exists in the
langchain-openai package and should be used instead. To use it
run `pip install -U langchain-openai`
and import as `from langchain_openai import ChatOpenAI`."
when there is no actual problem, only the erronious deprication warning, the line
used in the code is:
from langchain_community.chat_models import ChatOpenAI
The warning says "from LangChain import ChatOpenAI" is deprecated, but that is
a non sequetor, as "from LangChain import ChatOpenAI" is NOT BEING USED.
And the above suggestion is broken: from langchain_openai import ChatOpenAI (DO NOT USE THIS)
Do NOT use this:
# from langchain_openai import ChatOpenAI # do NOT use this, it is broken or wrong or both
This causes a massive rampup in cpu usage for ~80-90 sec before completing the process.
This may not happen, or it may always happen, randomly, for the exact same task.
the working solution is:
from langchain_community.chat_models import ChatOpenAI # correct source
"langchain_community" is a correct source

As an inexperienced Python developer, I do not know how to make the code work without researching Python's co-routines and the `async/await` pattern.
The code in the docs shows me the following error which does not explain how to go about it the correct way:

### Error Message and Stack Trace (if applicable)
_No response_
### Description
As the code provided, I used SQLiteCache to store the result of Anthropic with tools.
**Run the _same code_ twice**, it is expected that
1. the second time is much faster than the first time
2. I do not see any log in Cloudflare AI Gateway during the second run
3. the SQLite database file is not written (i.e. file size is not increased) during the second run
But, what happend is that
1. the second time was as slow as the first time (no speed promotion)
2. I saw logs in Cloudflare AI Gateway during the second run
3. the SQLIte database file size was doubled after the second run
I have investegated the database file, found the `prompt` field of correspond records are completely same, and the `llm` field of correspond records have only one difference:
```diff
-"repr": "<langchain_community.cache.SQLiteCache object at 0x00000234A5107730>"
+"repr": "<langchain_community.cache.SQLiteCache object at 0x00000195B402AA40>"
```
I have another Linux with langchain-community==0.0.36 and Anthropic without tools, which could hit the cache.

### Example Code
I am using the following code to get a response asynchronously and it works fine
```
conversational_rag_chain = RunnableWithMessageHistory(
rag_chain,
get_session_history=self.get_message_history,
input_messages_key="input",
history_messages_key="chat_history",
output_messages_key="answer",
)
self.message_history.add_user_message(search)
answer = conversational_rag_chain.invoke({
"input": search
},
config={
"configurable": {
"session_id": self.session_id
}
}
)["answer"]```
But when I change the invoke to stream as I did before, I don't get an input at all
```
answer = conversational_rag_chain.stream({
"input": search
},
config={
"configurable": {
"session_id": self.session_id
}
}
)["answer"]```
### Error Message and Stack Trace (if applicable)
Am not getting an exception but a weird response,
Am getting a response and its only giving the input data only
{
"input": {the_question_I_asked}
}
This is exactly what I get in the response, followed the documentation and got nothing no different
### Description
I am trying to get the responses to be streamed back to me as they come from OpenAI, with that I will get lower latency and a much better feel compared to waiting for the entire data to be generated, am also working on voice which requires the data to come as a stream

### Description
The openai python library provides a `client` parameter that allows you to configure proxy settings, and disable ssl verification.
The langchain abstraction **ignores** this, and sets a default client, resulting in it not working.
For example, this is the openai equivalent which works
```python
import httpx
from openai import AzureOpenAI
PROXY="PROXY_IP:PORT" # redacted
AZURE_BASE = "insert base url here" # redacted
deployment_name= "gpt4model" # redacted
OPENAI_API_VERSION="2024-02-15-preview"
OPENAI_API_KEY="key" # redacted
http_client=httpx.Client(proxy=PROXY,verify=False, follow_redirects=True)
base_url = "https://AZURE_BASE/openai/deployments/deployment_name"
client = AzureOpenAI(api_key=OPENAI_API_KEY,api_version=OPENAI_API_VERSION,base_url=base_url,http_client=http_client)
client.chat.completions.create(model=deployment_name,messages=[{"role":"user","content":"test"}])
```
## Why?
After setting logging in `httpx` to debug, I discovered that the final client used by the langchain abstraction is a **new** one, probably created along the way. The client parameter passed down is lost along the way somewhere.
### Result from langchain client
The model parameter is wrong (supposed to be deployment_name) and also the host its connecting to is the base url instead of my proxy url.

### Result from openai client (correct)
Observe the differences in the model and host parameters. they are correctly set to deployment_name and the proxy url.
```python

```
## How to fix?
Honestly I have no idea. Theres too many magic abstractions going on here. The client parameter is being ignored somewhere down the line.
I poked into `AzureChatOpenAI` and saw `validate_environment` but I dont see it being called anywhere.
Digging into `BaseChatOpenAI` and `BaseChatModel` didnt do much good either.
How I fixed this on my end was a major hack - replacing the final client used with my httpx client after initialiation.
```python
from langchain_openai import AzureChatOpenAI
import httpx
base_url = "url"
client=httpx.Client(proxy="proxy",verify=False, follow_redirects=True)
model = AzureChatOpenAI(base_url=base_url,openai_api_version=OPENAI_API_VERSION, openai_api_key=OPENAI_API_KEY, temperature=0,client=client)
model.client._client._client = client # replace the SyncHttpxClientWrapper client with own httpx instance
model.invoke("this works")
```

### Example Code
def image_to_base64(image_data: bytes) -> str:
#image_data is 4804036
base64_image = base64.b64encode(image_data).decode('utf-8')
#base64_image size increase to 6405384
return base64_image
### Error Message and Stack Trace (if applicable)
botocore.exceptions.EventStreamError: An error occurred (validationException) when calling the InvokeModelWithResponseStream operation: messages.0.content.1.image.source.base64: image exceeds 5 MB maximum: 6405384 bytes > 5242880 bytes
### Description
Im trying to run query with image using Claude3-sonnet model with an input gif file of 4.6MB. I noticed that the size increase after we run base64 operation on the image data as needed for multimodel prompt. Is this expected?
We know that in anthropic claude at max support 5Mb of image file size per file. But now seems like the size will increase during the operation internally this is causing confusion.

- [X] I added a very descriptive title to this issue.
- [X] I included a link to the documentation page I am referring to (if applicable).
### Issue with current documentation:
Here's an example page that has this flaw: https://api.python.langchain.com/en/latest/langchain_api_reference.html#
So far every langchain API documentation page I have looked at is broken in this way.
Looking at the source code, this seems to be because those buttons are all disabled!
``` html
<div class="btn-group w-100 mb-2" role="group" aria-label="rellinks">
<a href="[#](view-source:https://api.python.langchain.com/en/latest/langchain_api_reference.html#)" role="button" class="btn sk-btn-rellink py-1 disabled"">Prev</a>
<a href="[#](view-source:https://api.python.langchain.com/en/latest/langchain_api_reference.html#)" role="button" class="btn sk-btn-rellink disabled py-1">Up</a>

</div>
```
I'd suggest either:
1. these buttons be made to work (no idea why they don't, but those hyperlinks look hinky -- shouldn't they link to other pages?) or
2. these buttons be stripped out of the pages
Right now these links just create confusion for the reader,

Although the conversation is summarized, the entire chat conversation is still sent to llm without pruning the summarized chats. However, this works as expected with default in-memory list in ConversationSummaryBufferMemory.
Example (work as expected):

)
conversation_with_summary = ConversationChain(

Yes, I am familiar with LangChain. It is a blockchain platform that focuses on language and translation services. It was founded in 2019 and has gained significant popularity in the tech industry. Is there something specific you would like to know about LangChain? I can provide you with more detailed information if needed.

### Description
I'm using a chatbot which is created by python langchain. In that I'm sending requests to the several LLM models (OPENAI , Claude, GEMINI). When I send requests to llm, first I summarize my previous chat. For summarize it I send my previous chats with a prompt mentioning to summarize this chat. It is done by ConversationSummaryBufferMemory using llm = ChatOpenAI(temperature=0, model_name=GPT3_MODEL) . By then I got that summary of the chat history and I stored it in a variable. After when I send my query to the LLM, I send it with the prompt , query and the summery of chat history that I have stored in a variable. But in the verbose I can see whole the chat history in the prompt instead of the summery of the previous chat. I the code chain_memory is the variable that I store the summery of the chat. chat_mem is the whole previous chat that I get from the postgres database. after Summarizing the previous chat It wil be send in to the StreamingChain to generate the response .

### Description
In the doc of langchain, it said chroma use cosine to measure the [distance](https://python.langchain.com/v0.1/docs/integrations/vectorstores/chroma/#:~:text=The%20returned%20distance%20score%20is%20cosine%20distance.%20Therefore%2C%20a%20lower%20score%20is%20better.) by default, but i found it actually use l2 distence, if we debug and follow into the code of the chroma db we can find that the default distance_fn is [l2](https://github.com/chroma-core/chroma/blob/6203deb45e21d6adc1d264087ddaff2f4627c2ac/chromadb/segment/impl/vector/brute_force_index.py#L32)

I have imported the langchain library for embeddings

And then built the embedding model like below:
```
embedding_model = AzureOpenAIEmbeddings(
azure_endpoint= AOAI_ENDPOINT,
openai_api_key = AOAI_KEY
)
```
When I try to run a simple _token, it succeeds
``` print(embedding_model._tokenize(["Test","Message"],2048)) ```
But if I try to embed a query, it throws an error saying 'Input should be a valid string'
``` print(embedding_model.embed_query("Test Message")) ```

### Description
I am trying to use langchain_openai.embeddings - AzureOpenAIEmbeddings. But I get an error when trying to embed even a simple string. I was trying to use the embedding_model with Vector Search but was getting an error and after some few hours of debugging I found that the embedding_model was having issue.
I tried to then figure out if it is an issue in the code, so I put the embedding code in the most simplest format and then tried to run it but still got error.

model = LlamaCppEmbeddings(

```
### Description
I have downloaded the Llama-3-8B model from https://huggingface.co/SanctumAI/Meta-Llama-3-8B-Instruct-GGUF and tried to run it in the typical Langchain flow to save the embeddings in a vector store.
However, I found several errors. The first, is that the call to `embed_query` (or similarly `embed_documents`) returns the error above. Analyzing the implementation of the method, it turns out that the `self.client.embed(text)` function returns `List[List[float]]` instead of `List[float]`:
```python
def embed_query(self, text: str) -> List[float]:
embedding = self.client.embed(text).
return list(map(float, embedding))
```
So, for the example above, `self.client.embed("Hello world")` returns as much lists as tokens (4 tokens, so 4 different embeddings):
```

]
```
However, running the same embedding on `llama.cpp` binary through:
```bash
$ ./embedding -m models/meta-llama-3-8b-instruct.Q4_K_M.gguf -p "Hello world" --seed 198
-1.294132, -2.531020, 2.608500, ...
```
just a single embedding. So:
- Is any of the implementation missing some parameterization to match outputs?
- Is any LlamaCppEmbeddings wrong implemented?

### Issue with current documentation:
Hello,
Firstly, thank you for releasing version v0.2 of the software. It's greatly appreciated!
I've noticed an issue with the documentation links. Several pages intended for v0.2 are mistakenly pointing to v0.1, which leads to broken URLs. For example, the URL:
https://python.langchain.com/v0.2/v0.1/docs/expression_language/primitives/parallel/
This should likely be:
https://python.langchain.com/v0.1/docs/expression_language/primitives/parallel/
Suggested Solution:
The URL seems to mistakenly include both versions (v0.2 and v0.1). Removing the incorrect segment (v0.2) should resolve the issue.
Thank you for your attention to this matter!

```
### Description
I'm trying to use the `JsonOutputFunctionParser` and realized that this is very specific for the OpenAI response and not for the Together API response:
OpenAI `message.additional_kwargs["function_call"]`:
`{'function_call': {'arguments': '{"query":"SELECT AVG(age) AS average_age FROM users"}', 'name': 'SQLQuery'}}`
Together `message.additional_kwargs["function_call"]`:
`None` -> Error
And this is because from function calls we receive this:
`{'tool_calls': [{'id': 'call_1x6sobhg8l5q95h7cozs28kq', 'function': {'arguments': '{"query":"SELECT AVG(age) FROM users"}', 'name': 'SQLQuery'}, 'type': 'function'}]}`
So the `JsonOutputFunctionParser` is not getting the `function` key-value. Will it be good to have a different `JsonOutputFunctionParser` for Together? It is easy to parse from Together since the output is very similar to the OpenAI response, it will need to get the `function` key instead of `function_call`.
I can work on that if you want.

### Example Code
In the following code:
```
vector_store = AzureSearch(...)
retriever = vector_store.as_retriever(
search_type = "similarity",
search_kwargs = {
"k": 8,
"search_type": 'hybrid',
"filters": "(x eq 'foo') and (y eq 'bar')" # Azure AI Search filter
}
)
```
When `_get_relevant_documents` is called, the provided `search_kwargs` are not used -- the defaults (k=4, similarity, no filter) are used instead. Although these are stored in the retriever in `_lc_kwargs`, this doesn't seem to be referenced anywhere.
This seemed to work before -- there may have been an issue introduced somewhere in between these versions:
langchain==0.1.16 -> 0.1.17
langchain-community==0.0.32 -> 0.0.36
langchain-core==0.1.42 -> 0.1.50
langchain-openai==0.1.3 ->0.1.6
I am using the retriever above as part of a custom doc retriever -- the work-around is for me to set `search_kwargs` directly in the retriever returned by `as_retriever` right before I call `get_relevant_documents`, rather than depending on the args I gave `as_retriever`. (I believe I got an error from pydantic if I try to set these earlier.)

with open(FILE_NAME, 'rb') as file:
# Correctly construct the multipart/form-data payload

}
# Make the POST request
response = requests.post(UNSTRUCTURED_API_URL, headers=headers, files=form_data, verify=False)
assert response.status_code == 200
```
Notice that I have to put verify = False because the site is hosted on a private website with a self signed certificate
however there is no option to do that with Langchain Document loader
```
def test_file_conversation_langchain():

docs = loader.load()
assert len(docs) > 0
```
This code will have until the Loader times out. The Unstructured Loader can't deal with the SSL certificate Error.

"""
Get a connection from the pool and perform an HTTP request. This is the
lowest level call for making a request, so you'll need to specify all
the raw details.
.. note::
More commonly, it's appropriate to use a convenience method
such as :meth:`request`.
.. note::
`release_conn` will only behave as expected if
`preload_content=False` because we want to make
`preload_content=False` the default behaviour someday soon without
breaking backwards compatibility.
:param method:
HTTP request method (such as GET, POST, PUT, etc.)
:param url:
The URL to perform the request on.
:param body:
Data to send in the request body, either :class:`str`, :class:`bytes`,
an iterable of :class:`str`/:class:`bytes`, or a file-like object.
:param headers:
Dictionary of custom headers to send, such as User-Agent,
If-None-Match, etc. If None, pool headers are used. If provided,
these headers completely replace any pool-specific headers.
:param retries:
Configure the number of retries to allow before raising a
:class:`~urllib3.exceptions.MaxRetryError` exception.
If ``None`` (default) will retry 3 times, see ``Retry.DEFAULT``. Pass a
:class:`~urllib3.util.retry.Retry` object for fine-grained control
over different types of retries.
Pass an integer number to retry connection errors that many times,
but no other types of errors. Pass zero to never retry.
If ``False``, then retries are disabled and any exception is raised
immediately. Also, instead of raising a MaxRetryError on redirects,
the redirect response will be returned.
:type retries: :class:`~urllib3.util.retry.Retry`, False, or an int.
:param redirect:
If True, automatically handle redirects (status codes 301, 302,
303, 307, 308). Each redirect counts as a retry. Disabling retries
will disable redirect, too.
:param assert_same_host:
If ``True``, will make sure that the host of the pool requests is
consistent else will raise HostChangedError. When ``False``, you can
use the pool on an HTTP proxy and request foreign hosts.
:param timeout:
If specified, overrides the default timeout for this one
request. It may be a float (in seconds) or an instance of
:class:`urllib3.util.Timeout`.
:param pool_timeout:
If set and the pool is set to block=True, then this method will
block for ``pool_timeout`` seconds and raise EmptyPoolError if no
connection is available within the time period.
:param bool preload_content:
If True, the response's body will be preloaded into memory.
:param bool decode_content:
If True, will attempt to decode the body based on the
'content-encoding' header.
:param release_conn:
If False, then the urlopen call will not release the connection
back into the pool once a response is received (but will release if
you read the entire contents of the response such as when
`preload_content=True`). This is useful if you're not preloading
the response's content immediately. You will need to call
``r.release_conn()`` on the response ``r`` to return the connection
back into the pool. If None, it takes the value of ``preload_content``
which defaults to ``True``.
:param bool chunked:
If True, urllib3 will send the body using chunked transfer
encoding. Otherwise, urllib3 will send the body using the standard
content-length form. Defaults to False.
:param int body_pos:
Position to seek to in file-like body in the event of a retry or
redirect. Typically this won't need to be set because urllib3 will
auto-populate the value when needed.

### Description
I'm trying to use Langchain to turn the incoming JSON from the UnstructuredAPI that I have hosted, into langhcin documents. I can reach the API, but getting it into Langchain format is proving difficult due to SSL certs. Adding a verify=False for SSL certs would be fantastic

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

### Issue with current documentation:
Description:
Currently, the load_query_constructor_runnable function documentation lacks doesn't have usage examples or scenarios, making it challenging for developers to understand.
URL to the documentation: https://api.python.langchain.com/en/latest/chains/langchain.chains.query_constructor.base.load_query_constructor_runnable.html#langchain.chains.query_constructor.base.load_query_constructor_runnable
### Idea or request for content:
I tried running the function and below is the complete code and output:
```python

from langchain.chains.query_constructor.schema import AttributeInfo
from langchain_openai import ChatOpenAI

product_name: Gizmo, price: $50
"""
attribute_info: AttributeInfo = [
{"name": "product_name", "type": "string"},
{"name": "price", "type": "number"},

runnable = load_query_constructor_runnable(

schema_prompt="Describe the query schema using allowed comparators and operators.",
fix_invalid=True,
)
# Now you can use the runnable to construct queries based on user input
user_input = "Show me products with price less than 30"
query = runnable.middle[0].invoke(user_input).content
print(f"Constructed query: {query}")
```
Output:
```bash
Constructed query: 1. Wireless Bluetooth Earbuds - $29.99
2. Portable Phone Charger - $24.99
3. Travel Makeup Bag - $19.99
4. Insulated Water Bottle - $15.99

### Error Message and Stack Trace (if applicable)
link: https://data.safetycli.com/v/66962/742/
The XMLOutputParser in LangChain uses the etree module from the XML parser in the standard python library which has some XML vulnerabilities; see: https://docs.python.org/3/library/xml.html This primarily affects users that combine an LLM (or agent) with the `XMLOutputParser` and expose the component via an endpoint on a web-service. This would allow a malicious party to attempt to manipulate the LLM to produce a malicious payload for the parser that would compromise the availability of the service. A successful attack is predicated on: 1. Usage of XMLOutputParser 2. Passing of malicious input into the XMLOutputParser either directly or by trying to manipulate an LLM to do so on the users behalf 3. Exposing the component via a web-service See CVE-2024-1455.

### Example Code
`FAISS._similarity_search_with_score_by_vector` includes the following code:
```
...
if score_threshold is not None:
cmp = (
operator.ge
if self.distance_strategy
in (DistanceStrategy.MAX_INNER_PRODUCT, DistanceStrategy.JACCARD)
else operator.le
)
docs = [
(doc, similarity)
for doc, similarity in docs
if cmp(similarity, score_threshold)
]
...
docs_and_rel_scores = [
(doc, relevance_score_fn(score)) for doc, score in docs_and_scores
]
...
```
in other words the entries are filtered by score. This happens **before** the `relevance_fn` has been applied.
However, after this first filtering step the filtering happens again in `VectorStore.similarity_search_with_relevance_scores` this time **after** the relevancy_fn has been applied.
```
...
docs_and_similarities = self._similarity_search_with_relevance_scores(
...
if score_threshold is not None:
docs_and_similarities = [
(doc, similarity)
for doc, similarity in docs_and_similarities
if similarity >= score_threshold
]
if len(docs_and_similarities) == 0:

I have noticed that in most LCEL examples, the llm module is only executed once. Of course, I know that there is a batch interface that can handle multiple batch situations, but the premise is that each one in the batch is independent. However, I want to implement a loop like structure where the model executes the results of the first round, adds them to the input of the second round, and then produces the final result.

### Example Code
When I use the map_reduce mode of load_summarize_chain with prompt in version 0.1.16 of langchain to summarize the two pdf documents ( The names of the two papers are `LLM+P: Empowering Large Language Models
with Optimal Planning Proficiency` and `Learning to Prompt for Vision-Language Models`) in `/home/user/mytest`, I encounter output_text being occasionally empty. (Here is download links for both articles: https://arxiv.org/pdf/2304.11477, https://arxiv.org/pdf/2109.01134)
Here is the code in question :

```
### Description
The main problematic code is as follows：`chain = load_summarize_chain(llm, chain_type="map_reduce", return_intermediate_steps=True, map_prompt=PROMPT, combine_prompt=PROMPT)`.
When my input parameters have prompt, my summary output looks like this：
```

{'intermediate_steps': [' \n\nThe paper "Learning to Prompt for Vision-Language Models" by Kaiyang Zhou, Jingkang Yang, Chen Change Loy, and Ziwei Liu presents a method called Context Optimization (CoOp) to improve the performance of large pre-trained vision-language models like CLIP in downstream image recognition tasks. Prompt engineering, which involves designing natural language prompts for classifying images, is challenging and time-consuming. CoOp addresses this by using learnable vectors to model prompt context words while keeping the pre-trained model parameters unchanged. It offers two implementations: unified context and class-specific context. Experiments on 11 datasets show that CoOp outperforms hand-crafted prompts with as few as one or two shots and significantly improves performance with more shots. It also demonstrates strong domain generalization compared to zero-shot models using hand-crafted prompts.', ' \n\nThe study focuses on the comparison between prompt engineering and Context Optimization (CoOp) in the context of pre-trained vision-language models. Prompt engineering, which involves finding the best wordings for class descriptions, can significantly impact performance but is time-consuming and requires task-specific knowledge. An example is shown where adding "a" before a class token in Caltech101 improves accuracy by over 5%. CoOp, on the other hand, automates this process by using learnable vectors to model context words. It offers two implementations: one with unified context for all classes and another with class-specific context for fine-grained categories. During training, CoOp adjusts context vectors while keeping the pre-trained model parameters fixed, effectively learning task-relevant context from the model\'s knowledge.', ' CoOp is a method that enables the knowledge from a pre-trained vision-language model to be refined through text encoding for specific learning tasks. It is demonstrated through benchmarking on 11 diverse visual recognition datasets, including object, scene, action, and fine-grained classification, as well as texture and satellite imagery recognition. CoOp proves to be effective in converting these models into efficient visual learners, needing only one or two training examples (few-shot learning) to outperform hand-crafted prompts. The performance can be further improved. Pronounced as /ku:p/.', ' \n\nThe paper "Learning to Prompt for Vision-Language Models 3" explores the adaptation of vision-language models in downstream tasks, identifying prompt engineering as a critical issue. To address this, the authors propose CoOp, a continuous prompt learning approach with two implementations for different recognition tasks. CoOp surpasses manually crafted prompts and linear probe models in both performance and robustness to domain shifts. The study is the first to show these improvements for large vision-language models. The open-source project aims to facilitate future research on efficient adaptation methods, contributing to the democratization of foundation models. The work is related to advancements in text representation, large-scale contrastive learning, and web-scale datasets, like CLIP and ALIGN. It also connects to prompt learning in NLP but focuses on facilitating the deployment of vision-language models in various applications.', ' \nThis text discusses the use of pre-trained language models to generate answers based on cloze-style prompts, which can improve downstream tasks like sentiment analysis. Jiang et al. (2020) propose generating candidate prompts through text mining and paraphrasing, selecting the best ones for highest accuracy. Shin et al. (2020) use a gradient-based method to find significant tokens. Continuous prompt learning methods (Zhong et al., 2021; Li and Liang, 2021; Lester et al., 2021) optimize word embedding vectors but lack clear visualization of learned words. Liu et al. (2021a) provide a comprehensive survey on prompt learning in NLP. The authors highlight their novel work in applying prompt learning to adapt large vision models, which is a first in the field.', " The paper by Kaiyang Zhou et al. presents a technique called Context Optimization (CoOp) for improving the performance of vision-language models, specifically CLIP, in computer vision tasks. CoOp models the context of a prompt using learnable vectors, which are optimized to maximize the score for the correct class. The approach has two designs: unified context, where all classes share context vectors, and class-specific context, where each class has its own set of vectors. The study shows that prompt learning not only enhances transfer learning performance but also results in models that are robust to domain shifts. The methodology section discusses the vision-language pre-training process with a focus on CLIP's architecture.", ' \n\nCLIP (Contrastive Language-Image Pre-training) is a model with two encoders, one for images (using CNNs like ResNet-50 or ViT) and the other for text (based on Transformers). It converts input text into a byte pair encoding (BPE) representation and maps it to fixed-length word embeddings. CLIP is trained using a contrastive loss to align image and text embedding spaces, using a dataset of 400 million image-text pairs. This enables it to perform zero-shot recognition by comparing image features with classification weights synthesized from text prompts specifying class names.', " \nThe paper proposes a method called Context Optimization (CoOp) for improving the performance of Vision-Language Models, specifically CLIP, in Few-Shot Learning tasks. CoOp avoids manual prompt tuning by using continuous context vectors learned from data, while keeping the pre-trained model parameters frozen. There are two implementations: Unified Context, where a shared context is used for all classes, and Class-Specific Context, where each class has its own unique context vectors. The prediction probability is computed using cosine similarity between the text encoder's output and the image feature. The approach aims to adapt large vision-language models for open-set visual concepts, making the representations more transferable to downstream tasks. Experiments are conducted on 11 image classification datasets, including ImageNet and Oxford-Pets.", ' \n\nThis benchmark consists of 12 diverse datasets: Caltech101, Oxford-Pets, StanfordCars, Flowers102, Food101, FGVCAircraft, SUN397, DTD, EuroSAT, and UCF101, each with varying statistics. These datasets are used for a wide range of visual tasks such as generic and fine-grained object classification, scene recognition, action identification, and specialized tasks like texture and satellite image recognition, providing a comprehensive evaluation platform for computer vision algorithms.', ' \n\nThe study by Kaiyang Zhou et al. demonstrates the effectiveness of CoOp, a method that enhances the few-shot learning capabilities of the CLIP model. CoOp transforms CLIP into a strong learner, outperforming zero-shot CLIP and linear probe approaches when tested on 11 datasets. The evaluation follows the protocol of CLIP, using 1 to 16 shots for training and averaging results from three runs. CoOp comes in four variations based on class token positioning and context options. The default setup employs a ResNet-50 image encoder with 16 context tokens. Other design choices are explored further in the study.', " \n\nThe paper focuses on improving Vision-Language Models, specifically using a method called CoOp, which is built on CLIP's open-source code. CoOp's context vectors are initialized randomly with a zero-mean Gaussian distribution and trained using SGD with an initial learning rate of 0.002, decaying by cosine annealing. The maximum epoch varies based on the number of shots. To prevent gradient explosions, a warm-up trick with a fixed learning rate is used in the first epoch. \n\nTwo baseline methods are compared: zero-shot CLIP, which relies on hand-crafted prompts, and a linear probe model. The linear probe model, trained on top of CLIP's features, is simple yet performs comparably to sophisticated few-shot learning methods. \n\nCoOp significantly outperforms hand-crafted prompts, particularly on specialized tasks like EuroSAT and DTD, with performance increases of over 45% and 20%, respectively. It also shows notable improvements on fine-grained and scene recognition datasets. However, on OxfordPets and Food101, the performance gains are less substantial, possibly due to overfitting. \n\nCoOp also surpasses the linear probe model in overall performance, demonstrating its capability to learn task-relevant prompts efficiently.", ' \nCLIP+CoOp outperforms the linear probe model in terms of overall performance, especially in low-data scenarios like one or two shots. CoOp shows greater effectiveness for few-shot learning, while the linear probe model is competitive on specialized and fine-grained datasets due to the strength of the pre-trained CLIP space. However, both methods encounter challenges with the noisy Food101 dataset.', " \n\nThe study compares the robustness of CLIP (a zero-shot learning model) and CoOp (a prompting method) to distribution shifts using different vision backbones. CoOp outperforms linear probe CLIP on various datasets, showing better potential with more shots. Using unified context generally yields better performance, except for some fine-grained datasets and low-data scenarios where class-specific context (CSC) is more effective. CoOp's domain generalization is evaluated against zero-shot CLIP and linear probe, with ImageNetV2, ImageNet-Sketch, ImageNet-A, and ImageNet-R as target datasets. CoOp demonstrates improved performance relative to the linear probe but is less robust than zero-shot CLIP in distribution shifts.", " \n\nThe study examines prompt learning for Vision-Language Models (VLMs), specifically CoOp, and its impact on model performance and robustness. It is observed that CoOp improves CLIP's robustness to distribution shifts, even without direct exposure to the source dataset. Shorter context lengths enhance domain generalization, possibly due to reduced overfitting, whereas longer context lengths lead to better performance. CoOp consistently outperforms prompt engineering and prompt ensembling across various vision backbones, including ResNet and ViT, with the performance gap being more significant with advanced backbones. The comparison with prompt ensembling, using hand-crafted prompts, highlights CoOp's advantage, indicating the learned prompts' generalizability and effectiveness.", " \n\nThe study by Zhou et al. introduces CoOp, a prompt learning method for fine-tuning large pre-trained vision-language models like CLIP. CoOp outperforms other fine-tuning techniques, such as tuning the image encoder or adding transformation layers. It shows that fine-tuning the text encoder with learned prompts is more effective. CoOp's initialization method doesn't significantly impact performance, and random initialization can be used. However, interpreting the learned prompts is challenging due to the continuous space optimization. The study highlights the potential of prompt learning for vision models but also notes CoOp's difficulty in interpretation and sensitivity to noisy labels. It opens up avenues for future research, including cross-dataset transfer and test-time adaptation.", " \n\nThis work highlights the need for future research on efficient adaptation methods for foundation models, specifically in areas like cross-dataset transfer and test-time adaptation. It also suggests exploring generic adaptation techniques for large-scale vision models. The study's findings and insights are intended to guide future research in this emerging field, which is still in its early stages. The work is supported by various funding sources and the corresponding author is Ziwei Liu. The appendix provides details on the datasets used, including???? for 11 datasets and four ImageNet variants, as well as the prompts employed for zero-shot CLIP. Caltech101 excludes specific classes, and for UCF101, the middle frame of each video serves as input.", ' \n\nThe summary discusses two studies on improving the performance of vision-language models, particularly CLIP, through prompting techniques. CoOp, a method for learning to prompt, is presented, with Table 4 showing the nearest words for its learned context vectors. CoOp is compared with other fine-tuning methods on ImageNet (Table 5) and demonstrates improved performance (+4.77) with only 16 shots. The study also evaluates CoOp and CoCoOp on the DOSCO-2k benchmark (Table 7), which focuses on domain generalization. Both learnable methods outperform zero-shot learning, with CoOp having a higher average performance. These results highlight the potential of efficient adaptation methods like CoOp and CoCoOp for transfer learning tasks.', ' \n\nThe referenced works explore advancements in machine learning, particularly in the areas of visual and language representation. \n\n1.

Summary for: /home/mnt/User/PycharmProjects/pythonProject/documents/llm_planning_paper.pdf
{'intermediate_steps': [' The paper presents LLM+P, a framework that enhances large language models (LLMs) with the ability to solve complex planning problems optimally. By integrating classical planners, LLM+P converts natural language descriptions of planning tasks into PDDL files, finds solutions efficiently, and translates them back into natural language. The study shows that LLM+P outperforms LLMs in providing optimal solutions for robot planning scenarios, while LLMs often fail to generate feasible plans. The framework is demonstrated through experiments and a real-world robot manipulation task. LLMs currently excel in linguistic competence but lack functional competence, especially in problem-solving tasks requiring understanding of the world.', ' The text describes a block-stacking problem with specific goals, and presents a step-by-step solution. It then raises the question of whether large language models (LLMs) should be trained on arithmetic and planning problems, considering existing tools for correct answers. The research discussed in the paper focuses on enabling LLMs to solve planning problems correctly without modifying the models themselves, through a methodology called LLM+P. When given a natural language description of a planning problem, the LLM outputs a problem description that can be used as input for a symbolic planner.', " \n\nThe LLMPlan approach combines a Large Language Model (LLM) with a classical PDDL planner to solve planning problems more effectively than using an LLM alone. It involves three steps: 1) the LLM generates a PDDL description of the problem from natural language input, 2) a general-purpose planner solves the PDDL-formulated problem, and 3) the resulting plan is translated back to natural language using the LLM. This method shows promise in extending to other problem classes with sound solvers, like arithmetic problems. However, the current work doesn't address recognizing prompts suitable for the LLM+P pipeline, which is identified as a future research direction. The planning problem is formally defined using the states, initial state, goal states, actions, and state transition function. PDDL is a standard encoding for these problems, consisting of a domain file and a problem file that describe the rules and specific instance of the problem. The proposed method aims to translate natural language prompts into PDDL for efficient solving by planners.", ' \n\nThe method described here uses large language models (LLMs) to convert planning prompts in natural language into PDDL (Planning Domain Definition Language) format, which is understood by symbolic planners. The LLMs, despite being weak in planning tasks, are adept at text processing and can translate prompts into PDDL, essentially performing "machine translation." The process involves in-context learning, where the LLM learns from a few input-output examples provided alongside the prompt. When GPT-4, a large language model, is given a context and problem description, it generates a solvable PDDL file. The proposed LLM+P approach combines LLMs with classical planners, assuming that a human expert provides a fixed domain description in PDDL for all problem instances. This method can be used as a natural language interface for assigning tasks to robots, like a bartender making cocktails, with the robot inferring the most efficient plan based on given ingredients. A minimal example of a PDDL problem is assumed to be available for the model to learn from.', " \n\nThe LLM+P pipeline is a method that combines large language models (LLMs) with classical planning algorithms for solving complex robot tasks. The agent, upon receiving a new task described in natural language, uses the LLM's in-context learning to infer the corresponding PDDL problem file. This file is then combined with a pre-defined domain PDDL file, describing the robot's capabilities, to generate a plan using a classical planner. The LLM translates the generated PDDL plan back into natural language for execution. The assumptions for this approach include: the robot triggering LLM+P at the right time, a domain PDDL file, and a simple problem description in natural language. The work builds upon classical planning algorithms, which are sound and complete, and leverages LLMs for their zero-shot generalization ability in processing natural language tasks. Prior research has shown LLMs can be used for task planning and decomposing instructions for robots.", " \n\nSayCan is a method that allows robots to plan using affordance functions and natural language requests. However, current Large Language Models (LLMs) like ChatGPT struggle with long-horizon reasoning for complex tasks, often producing incorrect plans. To address this, recent works explore combining classical planning with LLMs, either through prompting or fine-tuning, to solve PDDL planning problems. Some studies improve long-horizon planning by iterative querying, as in Minecraft. In contrast, the proposed work aims to leverage both the planner's accuracy and LLM's generalization for translating natural language into PDDL.\n\nAdditionally, external modules have been used to enhance LLM performance, such as WebGPT integrating web knowledge, using search engines as tools, and human-in-the-loop systems like MemPrompt for error correction. Other examples include retrieval-augmented models like REPLUG and incorporating calculators for computation. The recent ToolFormer model learns to call specific tool APIs as needed. The work under discussion aims to combine the strengths of planners and LLMs without solely relying on the latter.", " \n\nThe paper presents a method called LLM+P, which enhances the capabilities of Large Language Models (LLMs) by integrating them with classical planners without requiring any fine-tuning or re-training. Unlike a concurrent work that integrated LLMs with PDDL using a limited dataset (SayCan), LLM+P offers a more comprehensive study on improving LLMs' long-horizon reasoning and planning abilities. The authors conduct experiments with seven diverse robot planning domains from past competitions and 20 tasks per domain to evaluate their approach. They use GPT-4 for generating text PDDL responses, which are then processed by the FAST-DOWNWARD planner. The results show that LLM+P outperforms a method called LLM-AS-P, highlights the importance of context, and demonstrates its potential in making service robots more efficient in realistic tasks. The dataset and codebase are made publicly available for reproducibility.", ' \n\nThe paper evaluates the performance of different planning methods in seven domains. The baseline methods are manually assessed for optimal plans, while the LLM-based approach, LLM-AS-P (adapted from Tree of Thoughts), uses a breadth-first-search algorithm and language model to generate plans. LLM+P is another variant considered. The success rates are presented in Table I. LLM-AS-P generates a plan for all problems but with varying success rates; it achieves 100% in BARMAN and 95% in GRIPPERS, but fails in other domains. LLM+P shows improved performance, particularly in GRIPPERS and BLOCKSWORLD. The study highlights that while LLM-AS-P provides plans, they are often sub-optimal.', " \nThis study examines the use of large language models (LLMs) for generating optimal robot tidy-up plans. The robot's tasks include picking up and placing items in specific locations. The LLM-based approach called LLM-AS-P struggles with preconditions, tracking object states, complex spatial relationships, and long-horizon planning, often producing suboptimal plans or failing completely. However, the proposed method LLM+P, which combines LLMs with classical planners, successfully generates optimal plans for most problems. Context, in the form of example plans, is crucial for LLM+P's effectiveness. A real-world demonstration shows LLM+P solving a tidy-up task efficiently, while LLM-AS-P produces a less efficient plan. The study concludes that integrating classical planners enhances LLMs' planning capabilities for service robots.", " This work presents a method that combines large language models (LLMs) with classical planners for optimal planning. The LLM+P framework focuses on having LLMs convert natural language planning problems into PDDL, a structured planning language. In-context learning is enhanced by providing LLMs with a demonstration or context of a (problem, PDDL) pair. Future research aims to develop LLM's ability to automatically determine when and how to apply this framework and decrease reliance on human-provided information, possibly through finetuning.", ' \n\nThe references listed cover a range of topics in natural language processing, robotics, and artificial intelligence.

### Issue with current documentation:
I don't see any usage examples for `RetryWithErrorOutputParser`. I'd like to update the following code that uses `chain.with_retry` to use retry with errors instead, but it's not clear how from the documentation:
```python
sonnet = ChatBedrock(model_id="anthropic.claude-3-sonnet-20240229-v1:0")
parser = PydanticOutputParser(pydantic_object=GeneratePlanStructAPI)
generate_args_for_gen_plan_struct_prompt_template = """
You are an expert at reading natural language feedback and generating the most relevant API arguments.
Look at the previous arguments and feedback below and generate the most appropriate arguments for the API endpoint.
Only modify arguments that are relevant to the feedback; leave the rest as they are.
Previous arguments:
{previous_generate_args}
User feedback: {feedback}
Important: Only output valid parsable JSON without any descriptions or comments. Follow the formatting instructions below:
{format_instructions}
"""
prompt = PromptTemplate(
template=generate_args_for_gen_plan_struct_prompt_template,
input_variables=["previous_generate_args", "feedback"],
partial_variables={"format_instructions": parser.get_format_instructions()},
)
chain = prompt | sonnet | parser
retryable_gen_plan_chain = chain.with_retry(
retry_if_exception_type=(ValueError,), # Retry only on ValueError
wait_exponential_jitter=False,
stop_after_attempt=5,
)
feedback = "I want to workout more days per week and do more cardio"
previous_generate_args = {
"workout_prefs": ('strength', 'strength', 'intro'),
"num_days": 3,
}
create_args = retryable_gen_plan_chain.invoke({"previous_generate_args": previous_generate_args, "feedback": feedback})
```

I calculated that each time I submit to GPT, it will cost me prompt: 20214 tokens and completion: 358 tokens. The TPM limit of gpt-4-32k is 80k TPM. So why do I make 7 requests at the same time in the same minute and why are no requests blocked?

```
### Error Message and Stack Trace (if applicable)
"module 'playwright.async_api' has no attribute 'AsyncBrowser'"
### Description
After 1 hour of investigation here is my findings:
- The issue is introduced by [this commit](https://github.com/langchain-ai/langchain/commit/9639457222afac372de7ef8fa722434e7692935a)
- As you [can](https://github.com/microsoft/playwright-python/blob/release-1.43/playwright/async_api/__init__.py) [see](https://github.com/microsoft/playwright-python/blob/release-1.43/playwright/async_api/__init__.py) from playwright-python source code, there is no AsyncBrowser or SyncBrowser exports. They were correctly imported ``Browser as AsyncBrowser`` ``Browser as SyncBrowser`` in the past but [this](https://github.com/langchain-ai/langchain/pull/21156/commits/ec8df9e2de997d4cf3a8f0633166b3634bdaaeed#diff-a98f55f30d9f1733f6e399517dd5fbc4d74e9a16ad0840d3b51e3e3fd1ca59b9) PR broke it.
- As a side note to the mentioned PR, the ``lazy_import_playwright_browsers`` uses ``guard_import`` for both of the browsers(although the name of the class called from the module is incorrect), but still ``guard_import`` is called inside ``validate_browser_provided`` and ``from_browser`` again. These 2 functions can just call ``lazy_import_playwright_browsers`` instead of repeating your self 6 times. Just call ``lazy_import_playwright_browsers`` inside the mentions methods.
- The ``lazy_import_playwright_browsers`` body should look like:
```python
def lazy_import_playwright_browsers() -> Tuple[Type[AsyncBrowser], Type[SyncBrowser]]:
"""
Lazy import playwright browsers.
Returns:
Tuple[Type[AsyncBrowser], Type[SyncBrowser]]:
AsyncBrowser and SyncBrowser classes.
"""
return (
guard_import(module_name="playwright.async_api").Browser,
guard_import(module_name="playwright.sync_api").Browser,
)
```
- Side note on `libs/community/langchain_community/tools/gmail/utils.py` changes introduced by the commit:
All the import functions ``import_googleapiclient_resource_builder``, ``import_google``, ``import_installed_app_flow`` were changed to use ``guard_import`` but later in the body of the functions ``get_gmail_credentials`` ``build_resource_service`` instead of using these functions, ``guard_import`` were called again(instead of just calling the import functions directly) to import classes from google libraries. this is obviously a code smell.
I can submit a PR for this

### Example Code
The bug was introduced in `langchain/libs/core/langchain_core/language_models/chat_models.py` [(link to master)](https://github.com/langchain-ai/langchain/blob/master/libs/core/langchain_core/language_models/chat_models.py#L297) since [v0.1.14](https://github.com/langchain-ai/langchain/blob/v0.1.14/libs/core/langchain_core/language_models/chat_models.py#L289).
First, note the definition of the `BaseChatModel._astream()` method [(link to master)](https://github.com/langchain-ai/langchain/blob/master/libs/core/langchain_core/language_models/chat_models.py#L773C1-L779C45):
```
async def _astream(
self,
messages: List[BaseMessage],
stop: Optional[List[str]] = None,
run_manager: Optional[AsyncCallbackManagerForLLMRun] = None,
**kwargs: Any,
) -> AsyncIterator[ChatGenerationChunk]:
```
It accepts the optional `run_manager: Optional[AsyncCallbackManagerForLLMRun]` parameter.
That's how `BaseChatModel.astream()` calls `BaseChatModel._astream()` [(link to master)](https://github.com/langchain-ai/langchain/blob/master/libs/core/langchain_core/language_models/chat_models.py#L297), note that **it never passes the `run_manager` parameter**:
```
(run_manager,) = await callback_manager.on_chat_model_start(
dumpd(self),
[messages],
invocation_params=params,
options=options,
name=config.get("run_name"),
run_id=config.pop("run_id", None),
batch_size=1,
)
generation: Optional[ChatGenerationChunk] = None
try:
async for chunk in self._astream(
messages,
stop=stop,
**kwargs,
):
```
That's how `BaseChatModel.astream()` used to call `BaseChatModel._astream()` in [v0.1.13](https://github.com/langchain-ai/langchain/blob/v0.1.13/libs/core/langchain_core/language_models/chat_models.py#L290), note that the `run_manager` object used to be passed properly:
```
(run_manager,) = await callback_manager.on_chat_model_start(
dumpd(self),
[messages],
invocation_params=params,
options=options,
name=config.get("run_name"),
run_id=config.pop("run_id", None),
batch_size=1,
)
generation: Optional[ChatGenerationChunk] = None
try:
async for chunk in self._astream(
messages,
stop=stop,
run_manager=run_manager,
**kwargs,
):
```
[As stated in the current docs](https://python.langchain.com/docs/modules/model_io/chat/custom_chat_model/#base-chat-model), `BaseChatMode._astream()` method can be overridden by users, so preserving the same API within minor version updates is important. That's why I consider this a bug.
### Error Message and Stack Trace (if applicable)
_No response_
### Description
I am using a `RunnableConfig` object to pass the chat ID through the whole pipeline for logging purposes:
```
async for event in my_chain.astream(
input={"question": ...},
config=RunnableConfig(metadata={"chat_id": chat.id}),
):
```
Then I try to get the chat ID back in my custom model derived from `BaseChatModel` like this:
```
async def _astream(
self,
messages: List[BaseMessage],
stop: Optional[List[str]] = None,
run_manager: Optional[AsyncCallbackManagerForLLMRun] = None,
**kwargs: Any,
) -> AsyncIterator[ChatGenerationChunk]:
if not run_manager.metadata.get("chat_id"):
raise ValueError("chat_id is required to extract the logger")
chat_id = run_manager.metadata["chat_id"]
...
```
This code worked perfectly fine in [v0.1.13](https://github.com/langchain-ai/langchain/blob/v0.1.13/libs/core/langchain_core/language_models/chat_models.py#L290).
Starting with [v.0.1.14](https://github.com/langchain-ai/langchain/blob/v0.1.14/libs/core/langchain_core/language_models/chat_models.py#L289) and up to the current [master](https://github.com/langchain-ai/langchain/blob/master/libs/core/langchain_core/language_models/chat_models.py#L297), the `run_manager` object is never passed inside the `BaseChatModel._astream()` method. Hence, my code always sees `run_manager == None` and fails with the `ValueError` exception.

### Example Code
The following python code can be used for reproducibility
```
import random
import asyncio
from langchain_core.runnables import RunnableLambda
from langchain_core.runnables.retry import RunnableRetry
def random_exception(a):
if random.randint(0, 2) < 2:
raise Exception(f"Failed {a}")
else:
return f"Pass {a}"
_chain = RunnableLambda(random_exception)
chain = RunnableRetry(
bound=_chain,
retry_exception_types=(
Exception,
),
max_attempt_number=2,
wait_exponential_jitter=True,
)
# output = chain.batch([1, 2, 3, 4, 5], return_exceptions=True)
coro = chain.abatch([1, 2, 3, 4, 5], return_exceptions=True)
output = asyncio.get_event_loop().run_until_complete(coro)
print(output)
```
### Error Message and Stack Trace (if applicable)
Output of this function
```
['Pass 1', 'Pass 1', Exception('Failed 2'), Exception('Failed 3'), 'Pass 5']
```
As can we seen output of 1st function is copied into 2nd, output of second copied into 3rd and so on
### Description
I found the issue, it is inside code in both _batch() and _abatch method, pasted below line of code
```
def _batch(
self,
inputs: List[Input],
run_manager: List["CallbackManagerForChainRun"],
config: List[RunnableConfig],
**kwargs: Any,
) -> List[Union[Output, Exception]]:
results_map: Dict[int, Output] = {}
def pending(iterable: List[U]) -> List[U]:
return [item for idx, item in enumerate(iterable) if idx not in results_map]
try:
for attempt in self._sync_retrying():
with attempt:
# Get the results of the inputs that have not succeeded yet.
result = super().batch(
pending(inputs),
self._patch_config_list(
pending(config), pending(run_manager), attempt.retry_state
),
return_exceptions=True,
**kwargs,
)
# Register the results of the inputs that have succeeded.
first_exception = None
for i, r in enumerate(result):
if isinstance(r, Exception):
if not first_exception:
first_exception = r
continue
results_map[i] = r
# If any exception occurred, raise it, to retry the failed ones
if first_exception:
raise first_exception
if (
attempt.retry_state.outcome
and not attempt.retry_state.outcome.failed
):
attempt.retry_state.set_result(result)
except RetryError as e:
try:
result
except UnboundLocalError:
result = cast(List[Output], [e] * len(inputs))
outputs: List[Union[Output, Exception]] = []
for idx, _ in enumerate(inputs):
if idx in results_map:
outputs.append(results_map[idx])
else:
outputs.append(result.pop(0))
return outputs
```
if you look closely to last for loop preparing the `outputs` object, there are 2 assumptions
1. results_map : should contain only those results that are passed
2. result: should contain all failed exceptions
There are 2 issues in this code
1. Result also contains no_exception output, because we are not filtering result after last attempt
2. In between attempt we are overriding result map because of this lines, here idx is not original idx but of a filtered inputs
```
for i, r in enumerate(result):
if isinstance(r, Exception):
if not first_exception:
first_exception = r
continue
results_map[i] = r
```

### Issue with current documentation:
Summary:
I've noticed an inconsistency in the parameter name for the API key in the OpenAI Embeddings library.
The error message indicates a different parameter name than what the library code expects.
Detailed Explanation:
Upon failing to initialize OpenAI Embeddings due to a missing API key, the following error is generated:
`ValidationError: 1 validation error for OpenAIEmbeddings
__root__
Did not find openai_api_key, please add an environment variable `OPENAI_API_KEY` which contains it, or pass `openai_api_key` as a named parameter. (type=value_error)
`
This error message requests openai_api_key either as an environment variable or a direct parameter.
However, the library seems to require the API key under the parameter name api_key.
This mismatch could lead to configuration errors and confusion among users.
Steps to Reproduce:
Attempt to initialize the OpenAI Embeddings without setting the API key.
Note the error message requesting openai_api_key.
Expected Behavior:
The error message should reflect the correct parameter name (api_key) as expected by the library.
Suggested Solution:
To enhance clarity and prevent confusion, I recommend either:
- Adjusting the error message to correctly ask for api_key.
- Modifying the code to accept openai_api_key as indicated by the error message.
Environment:
OpenAI version: 1.12.0
Python version: 3.10
Thank you for your attention to this matter and for your continued support in improving the library.
Best regards,

### Description
> So what's happening up here is I'm trying to use **ChatOllama** as a langchain agent, but it looks like my code breaks as soon as I try to create an instance of **AgentExecutor** class using model as **ChatOllama**.
> I investigated the langchain code-base and it looks like unlike "ChatOpenAI", "ChatOllama" is not compatible with AgentExecutor. As AgentExecutor calls Pydantic pipeline data and validations and ensures that it receives a Pydantic "BaseModel" as an argument, as you can see from above error message, it broke on validate_model function above:
``` values, fields_set, validation_error = validate_model(__pydantic_self__.__class__, data) ```
> One more thing to notice here is it's successfully creating "agent" instance and returns the required output "RunnalbeSequence" .
``` Agent type: <class 'langchain_core.runnables.base.RunnableSequence'> ```
> But the issue is with **pydantic method -> model_validation** as it doesn't allow, to run the flow.
> Somehow If you pass the **validation_check** in **pydantic** for **ChatOllama** we can use a free of cost model as an agent > and create advance LLM applications.

### Description
# Description
I am attempting to generate summaries for long documents using the Langchain library combined with Llama-3 model, but I encounter a ValueError indicating that "a single document was longer than the context length, we cannot handle this." This issue occurs even after splitting the document into smaller chunks.
# Expected Behavior
I expect the summary chain to generate concise summaries for each document chunk without exceeding the token limit.
# Actual Behavior
The process results in a ValueError as mentioned above, suggesting that the document chunks still exceed the token limit configured in the summary chain.
# Possible Solution
I suspect this might be related to how the RecursiveCharacterTextSplitter handles the tokenization and chunking, but I'm not sure how to adjust it correctly to ensure all chunks are within the acceptable token limit.
# Additional Context
I tried reducing the chunk_size and adjusting the chunk_overlap, but these attempts did not resolve the issue. Any guidance on how to ensure that the document chunks conform to the specified token limits would be greatly appreciated.

### Description
I'm trying to migrate from the deprecated convert_pydantic_to_openai_function with the previous Pydantic class, but the new function is not going beyond the first level. The produced output is
```json

"description": "List of tasks",
"parameters": {
"type": "object",
"properties": {},
"required": ["task_list"]
}
}
]
```
Is this a known bug, do i have to manually produce the full schema to pass as a dictionary now? I can't find anything in how to generate the full openai function using the new function.
Thanks

From some internet sleuthing it seems this is a problem specific to Windows?
If I put the code into a `.py` file and run it directly it does run correctly, so the environment is installed correctly, but it is a Jupyter-related invocation problem.
### Idea or request for content:
* If this is not supported on Windows, then the documentation should indicate as such.
* If there is a Windows-specific workaround then that should be documented.
* Ideally, of course, the example is copy-paste workable across all platforms. | DOC: AsyncChromiumLoader instructions do not work in Windows Jupyter notebook | https://api.github.com/repos/langchain-ai/langchain/issues/21246/comments | 1 | 2024-05-03T10:59:52Z | 2024-08-09T16:09:03Z | https://github.com/langchain-ai/langchain/issues/21246 | 2,277,437,821 | 21,246 |

### Example Code

### Error Message and Stack Trace (if applicable)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: Can't instantiate abstract class ListOutputParser with abstract method parse
### Description
* I'm trying to get multiple answers from a single llm call. I thought using `n=5` would be fine but found multiple issues with that: #1422 #8581 #6227 #8789
* But the suggested result is just to use a for loop and get the `.generations` attribute but I'm using LCEL so I struggle to find how I should change the output attribute.
* I tried removing the `StrOutputParser()` but I still get only one AIMessage instead of 5
* I planned to try using `ListOutputParser()` but couldn't even instantiate it, and there are no examples showing how to use it. (It's bad that there are no examples IMO)
edit: I just stumbled upon [an answer from dosu](https://github.com/langchain-ai/langchain/discussions/17153#discussioncomment-8390377) that might explain it:
> The output_parser in the LangChain codebase is implemented as an abstract base class BaseOutputParser with a derived class ListOutputParser. The ListOutputParser class has three subclasses: CommaSeparatedListOutputParser, NumberedListOutputParser, and MarkdownListOutputParser
So actually, ListOutputParser if more like a BaseClass, but it's really confusing that it's in the same "hierarchy" as StrOutputParser. And nothing in the [documentation of ListOutputParser](https://api.python.langchain.com/en/latest/output_parsers/langchain_core.output_parsers.list.ListOutputParser.html#langchain_core.output_parsers.list.ListOutputParser) seems to indicate that it should not be called directly.

As you can see here, Agent cannot extract the memory context correctly because it is not able to recognize which country's national anthem is being asked about, whereas you can clearly see in the Chat message history that Canada is the country in question. Is this a bug, and it actually works but is wrong in the docs? Or is there a new way to do this and docs haven't been updated?
