community: Correct Input API Key Name in Notebook and Enhance Readability of Comments for ZhipuAI Chat Model (#15529)
- **Description:** This update rectifies an error in the notebook by
changing the input variable from `zhipu_api_key` to `api_key`. It also
includes revisions to comments to improve program readability.
- **Issue:** The input variable in the notebook example should be
`api_key` instead of `zhipu_api_key`.
- **Dependencies:** No additional dependencies are required for this
change.

To ensure quality and standards, we have performed extensive linting and
testing. Commands such as make format, make lint, and make test have
been run from the root of the modified package to ensure compliance with
LangChain's coding standards.

community: Allow deleting by ID and collection in pgvector (#15627)
- **Description:** The `delete_collection` method deletes an entire
collection regardless of custom ID. The `delete` method deletes
everything with the provided custom IDs regardless of collection. It can
be useful to restrict deletion to both the collection and a set of
custom IDs. This change adds support for that by allowing you to
optionally specify that `delete` should be restricted to the collection
defined on the `PGVector` instance.

community: Fixed bug of "system message check" in chat_models/tongyi. (#15631)
- **Description:** This PR is to fix a bug of "system message check" in
langchain_community/ chat_models/tongyi.py

the chat messages, an error of "System message can only be the first
message." will be wrongly raised.
  - **Dependencies:** No.
  - **Twitter handle:** I don't have a Twitter account.

Adds `WasmChat` integration. `WasmChat` runs GGUF models locally or via
chat service in lightweight and secure WebAssembly containers. In this
PR, `WasmChatService` is introduced as the first step of the
integration. `WasmChatService` is driven by
[llama-api-server](https://github.com/second-state/llama-utils) and
[WasmEdge Runtime](https://wasmedge.org/).

Improvement: Allow passing parameters to the underlying es_client. Closes: #14403 (#14435)
### Description

In https://github.com/langchain-ai/langchain/issues/14403, the user
mentioned that he hopes not to verify ssl and needs to pass more
parameters

I found that the `Elasticsearch` class [has very many
parameters](98f2af2134/elasticsearch/_sync/client/__init__.py (L131-L191)
):

<img width="1097" alt="Screenshot 2023-12-08 at 4 24 39 PM"
src="https://github.com/langchain-ai/langchain/assets/10000925/f2201554-b41a-4388-a8e8-c14a2d0466d4">

In order to adapt to more situations, I want to add the kwargs parameter
so that users can enter more `Elasticsearch` parameters. Like
[redis](https://github.com/langchain-ai/langchain/blob/master/libs/langchain/langchain/vectorstores/redis/base.py#L253),
[tair](https://github.com/langchain-ai/langchain/blob/master/libs/langchain/langchain/vectorstores/tair.py#L32),
[myscale](https://github.com/langchain-ai/langchain/blob/master/libs/langchain/langchain/vectorstores/myscale.py#L112)
and so on.

Fix failing serpapi response processing for Google Maps API (#14817)
**Description:** Fix for processing for serpapi response for Google Maps
API
**Issue:** Due to the fact corresponding
[api](https://serpapi.com/google-maps-api) returns 'local_results' as
list, and old version requested `res["local_results"].keys()` of the
list. As the result we got exception: ```AttributeError: 'list' object
has no attribute 'keys'```.

Way to reproduce wrong behaviour:
```
    params = {
        "engine": "google_maps",
        "type": "search",
        "google_domain": "google.de",
        "ll": "@51.1917,10.525,14z",
        "hl": "de",
        "gl": "de",
    }
    search = SerpAPIWrapper(params=params)
    results = search.run("cafe")
```

add api_base to _client_params (community version of #14393) (#14644)
- **Description:** This PR adds `api_base` to `_client_params` in the
`chat_model` of LiteLLM to ensure it's included in API calls.
Previously, `api_base` was set on the client but was not included in the
parameters passed to the completion function. This change ensures that
`api_base` is correctly passed to all API calls.

This change addresses the issue where DashScopeEmbeddingAPI limits
requests to 25 lines of data, and DashScopeEmbeddings did not handle
cases with more than 25 lines, leading to errors. I have implemented a
fix to manage data exceeding this limit efficiently.

community: Integration of New Chat Model Based on ChatGLM3 via ZhipuAI API (#15105)
- **Description:** 
- This PR introduces a significant enhancement to the LangChain project
by integrating a new chat model powered by the third-generation base
large model, ChatGLM3, via the zhipuai API.
- This advanced model supports functionalities like function calls, code
interpretation, and intelligent Agent capabilities.
- The additions include the chat model itself, comprehensive
documentation in the form of Python notebook docs, and thorough testing
with both unit and integrated tests.
- **Dependencies:** This update relies on the ZhipuAI package as a key
dependency.
- **Twitter handle:** If this PR receives spotlight attention, we would
be honored to receive a mention for our integration of the advanced
ChatGLM3 model via the ZhipuAI API. Kindly tag us at @kaiwu.

To ensure quality and standards, we have performed extensive linting and
testing. Commands such as make format, make lint, and make test have
been run from the root of the modified package to ensure compliance with
LangChain's coding standards.

TO DO: Continue refining and enhancing both the unit tests and
integrated tests.

fix(minor): added missing **kwargs parameter to chroma query function (#14919)
**Description:**

This PR adds the `**kwargs` parameter to six calls in the `chroma.py`
package. All functions already were able to receive `kwargs` but they
were discarded before.

**Issue:**

When passing `kwargs` to functions in the `chroma.py` package they are
being ignored.

For example:

```
chroma_instance.similarity_search_with_score(
    query,
    k=100,
    include=["metadatas", "documents", "distances", "embeddings"],  # this parameter gets ignored
)
```
The `include` parameter does not get passed on to the next function and
does not have any effect.

Upgrades the Tongyi LLM and ChatTongyi Model (#14793)
- **Description:** fixes and upgrades for the Tongyi LLM and ChatTongyi
Model
      - Fixed typos; it should be `Tongyi`, not `OpenAI`.
- Fixed a bug in `stream_generate_with_retry`; it's a real stream
generator now.
- Fixed a bug in `validate_environment`; the `dashscope_api_key` should
be properly handled when set by environment variables or initialization
parameters.
- Changed the `dashscope` response to incremental output by setting the
parameter `incremental_output`, which eliminates the need for the
prefix-removal trick.
      - Removed some unused parameters, like `n`, `prefix_messages`.
      - Added `_stream` method.
- Added async methods support, such as `_astream`, `_agenerate`,
`_abatch`.
  - **Dependencies:** No new dependencies.
  - **Tag maintainer:** @hwchase17 

> PS: Some may be confused about the terms `dashscope`, `tongyi`, and
`Qwen`:
> - `dashscope`: A platform to deploy LLMs and provide APIs to invoke
the LLM.
> - `tongyi`: A brand name or overall term about Alibaba Cloud's LLM/AI.
> - `Qwen`: An LLM that is open-sourced and deployed in `dashscope`.
> 
> We use the `dashscope` SDK to interact with the `tongyi`-`Qwen` LLM.

core, community: propagate context between threads (#15171)
While using `chain.batch`, the default implementation uses a
`ThreadPoolExecutor` and run the chains in separate threads. An issue
with this approach is that that [the token counting
callback](https://python.langchain.com/docs/modules/callbacks/token_counting)
fails to work as a consequence of the context not being propagated
between threads. This PR adds context propagation to the new threads and
adds some thread synchronization in the OpenAI callback. With this
change, the token counting callback works as intended.

Having the context propagation change would be highly beneficial for
those implementing custom callbacks for similar functionalities as well.

### Description

I found that the methods in [the doctran

into [synchronized
versions](14944a59f7),

And [the example
ipynb](https://github.com/psychic-api/doctran/blob/main/examples.ipynb)
also shows that the code is synchronized, but the README has not been
updated yet.

so we need to modify the code and update the documentation.

Since `langchain_google_genai.ChatGoogleGenerativeAI` supported A public
image URL, we add to support it in `langchain.chat_models.ChatVertexAI`
as well.

### Example

```py
from langchain.chat_models.vertexai import ChatVertexAI
from langchain_core.messages import HumanMessage

llm = ChatVertexAI(model_name="gemini-pro-vision")
image_message = {
    "type": "image_url",
    "image_url": {
        "url": "https://python.langchain.com/assets/images/cell-18-output-1-0c7fb8b94ff032d51bfe1880d8370104.png",
    },
}
text_message = {
    "type": "text",
    "text": "What is shown in this image?",
}
message = HumanMessage(content=[text_message, image_message])

output = llm([message])
print(output.content)

Update arxiv.py with get_summaries_as_docs inside of Arxivloader (#14953)
Added the call function get_summaries_as_docs inside of Arxivloader

- **Description:** Added a function that returns the documents from
get_summaries_as_docs, as the call signature is present in the parent
file but never used from Arxivloader, this can be used from Arxivloader
itself just like .load() as both the signatures are same.
- **Issue:** Reduces time to load papers as no pdf is processed only
metadata is pulled from Arxiv allowing users for faster load times on
bulk loads. Users can then choose one or more paper and use ID directly
with .load() to load pdf thereby loading all the contents of the paper.

Community: Adds ability to pass a Config to the boto3 client used by Bedrock (#15029)
# Description  
This PR adds the ability to pass a `botocore.config.Config` instance to
the boto3 client instantiated by the Bedrock LLM.

Currently, the Bedrock LLM doesn't support a way to pass a Config, which
means that some settings (e.g., timeouts and retry configuration)
require instantiating a new boto3 client with a Config and then
replacing the LLM's client:

```python
llm = Bedrock(
        region_name='us-west-2',
        model_id="anthropic.claude-v2",
        model_kwargs={'max_tokens_to_sample': 4096, 'temperature': 0},
)

llm.client = boto_client('bedrock-runtime', region_name='us-west-2', config=Config({'read_timeout': 300}))
```

fix: correct spelling mistakes of "seperate, intialise, pre-defined" (#14647)
fix spellings

**seperate -> separate**: found more occurrences, see
https://github.com/langchain-ai/langchain/pull/14602
**initialise -> intialize**: the latter is more common in the repo
**pre-defined > predefined**: adding a comma after a prefix is a
delicate matter, but this is a generally accepted word

also, another word that appears in the repo is "fs" (stands for
filesystem), e.g., in `libs/core/langchain_core/prompts/loading.py`
` """Unified method for loading a prompt from LangChainHub or local
fs."""`
Isn't "filesystem" better?

community[minor]: Azure DocumentIntelligenceLoader/Parser support update with latest SDK (#14389)
- **Description:**
Add DocumentIntelligenceLoader & DocumentIntelligenceParser
implementation using the latest Azure Document Intelligence SDK with
markdown support.
The core logic resides in DocumentIntelligenceParser and
DocumentIntelligenceLoader is a mere wrapper of the parser.
The parser will takes api_endpoint and api_key and creates
DocumentIntelligenceClient for the user. 4 parsing modes are supported:
1. Markdown (default)
2. Single
3. Page 
4. Object

UT and notebook are also updated accordingly.

community[patch]: changed default for VertexAIEmbeddings (#14614)
Replace this entire comment with:
- **Description:** @kurtisvg has raised a point that it's a good idea to
have a fixed version for embeddings (since otherwise a user might run a
query with one version vs a vectorstore where another version was used).
In order to avoid breaking changes, I'd suggest to give users a warning,
and make a `model_name` a required argument in 1.5 months.

community: fix for surrealdb client 0.3.2 update + store and retrieve metadata (#14997)
Surrealdb client changes from 0.3.1 to 0.3.2 broke the surrealdb vectore
integration.
This PR updates the code to work with the updated client. The change is
backwards compatible with previous versions of surrealdb client.
Also expanded the vector store implementation to store and retrieve
metadata that's included with the document object.

community[patch]: Add param "task" to Databricks LLM to work around serialization of transform_output_fn (#14933)
**What is the reproduce code?**

```python
from langchain.chains import LLMChain, load_chain
from langchain.llms import Databricks
from langchain.prompts import PromptTemplate

def transform_output(response):
    # Extract the answer from the responses.
    return str(response["candidates"][0]["text"])

def transform_input(**request):
    full_prompt = f"""{request["prompt"]}
    Be Concise.
    """
    request["prompt"] = full_prompt
    return request

chat_model = Databricks(
    endpoint_name="llama2-13B-chat-Brambles",
    transform_input_fn=transform_input,
    transform_output_fn=transform_output,
    verbose=True,
)
print(f"Test chat model: {chat_model('What is Apache Spark')}") # This works

llm_chain = LLMChain(llm=chat_model, prompt=PromptTemplate.from_template("{chat_input}"))
llm_chain("colorful socks") # this works
llm_chain.save("databricks_llm_chain.yaml") # transform_input_fn and transform_output_fn are not serialized into the model yaml file
loaded_chain = load_chain("databricks_llm_chain.yaml") # The Databricks LLM is recreated with transform_input_fn=None, transform_output_fn=None.
loaded_chain("colorful socks") # Thus this errors. The transform_output_fn is needed to produce the correct output
```


Error:
```
 File "/local_disk0/.ephemeral_nfs/envs/pythonEnv-6c34afab-3473-421d-877f-1ef18930ef4d/lib/python3.10/site-packages/pydantic/v1/main.py", line 341, in __init__
    raise validation_error
pydantic.v1.error_wrappers.ValidationError: 1 validation error for Generation
text
  str type expected (type=type_error.str)
 request payload: {'query': 'What is a databricks notebook?'}'}
```

**What does the error mean?**

When the LLM generates an answer, represented by a Generation data
object. The Generation data object takes a str field called text, e.g.
Generation(text=”blah”). However, the Databricks LLM tried to put a
non-str to text, e.g. Generation(text={“candidates”:[{“text”: “blah”}]})
Thus, pydantic errors.

**Why the output format becomes incorrect after saving and loading the
Databricks LLM?**

Databrick LLM does not support serializing transform_input_fn and
transform_output_fn, so they are not serialized into the model yaml
file. When the Databricks LLM is loaded, it is recreated with
transform_input_fn=None, transform_output_fn=None. Without
transform_output_fn, the output text is not unwrapped, thus errors.

Missing transform_output_fn causes this error.
Missing transform_input_fn causes the additional prompt “Be Concise.” to
be lost after saving and loading.
