Fixes: ChatAnthropic was mutating the input message list during
formatting which isn't ideal bc you could be changing the behavior for
other chat models when using the same input

Update arize_callback.py (#6433)
Arize released a new Generative LLM Model Type, adjusting the callback
function to new logging.

Added arize imports, please delete if not necessary.

Specifically, this change makes sure that the prompt and response pairs
from LangChain agents are logged into Arize as a Generative LLM model,
instead of our previous categorical model. In order to do this, the
callback functions collects the necessary data and passes the data into
Arize using Python Pandas SDK.

Arize library, specifically pandas.logger is an additional dependency.

Update web_base.py _fetch() method For SiteMapLoader (#6256)
A must-include for SiteMap Loader to avoid the SSL verification error.
Setting the 'verify' to False by ``` sitemap_loader.requests_kwargs =
{"verify": False}``` does not bypass the SSL verification in some
websites.

There are websites (https:// researchadmin.asu.edu/ sitemap.xml) where
setting "verify" to False as shown below would not work:
sitemap_loader.requests_kwargs = {"verify": False} 

We need this merge to tell the Session to use a connector with a
specific argument about SSL:
 \# For SiteMap SSL verification
if not self.request_kwargs['verify']:
    connector = aiohttp.TCPConnector(ssl=False)
else:
    connector = None

Iterate through filtered file types instead of all listed files (#6258)
# Iterate through filtered file types instead of all listed files

Fixes https://github.com/hwchase17/langchain/issues/6257

https://github.com/hwchase17/langchain/pull/4926 originally added the
functionality to filter by file type, storing the filtered files in
`_files`

https://github.com/hwchase17/langchain/pull/5220 removed the
functionality when adding code to filter trashed files by using the
`files` variables instead of the `_files` variable.

This PR simply adds the functionality back by using `_files` again.

add max_context_size property in BaseOpenAI (#6239)
Hi, I make a small improvement for BaseOpenAI.

I added a max_context_size attribute to BaseOpenAI so that we can get
the max context size directly instead of only getting the maximum token
size of the prompt through the max_tokens_for_prompt method.

Fix LLM types so that they can be loaded from config dicts (#6235)
LLM configurations can be loaded from a Python dict (or JSON file
deserialized as dict) using the
[load_llm_from_config](8e1a7a8646/langchain/llms/loading.py (L12))
function.

However, the type string in the `type_to_cls_dict` lookup dict differs
from the type string defined in some LLM classes. This means that the
LLM object can be saved, but not loaded again, because the type strings
differ.

Fix output final text for HuggingFaceTextGenInference when streaming (#6211)
The LLM integration
[HuggingFaceTextGenInference](https://github.com/hwchase17/langchain/blob/master/langchain/llms/huggingface_text_gen_inference.py)
already has streaming support.

However, when streaming is enabled, it always returns an empty string as
the final output text when the LLM is finished. This is because `text`
is instantiated with an empty string and never updated.

This PR fixes the collection of the final output text by concatenating
new tokens.

Fix class promotion (#6187)
In LangChain, all module classes are enumerated in the `__init__.py`
file of the correspondent module. But some classes were missed and were
not included in the module `__init__.py`

This PR:
- added the missed classes to the module `__init__.py` files
- `__init__.py:__all_` variable value (a list of the class names) was
sorted
- `langchain.tools.sql_database.tool.QueryCheckerTool` was renamed into
the `QuerySQLCheckerTool` because it conflicted with
`langchain.tools.spark_sql.tool.QueryCheckerTool`
- changes to `pyproject.toml`:
  - added `pgvector` to `pyproject.toml:extended_testing`
- added `pandas` to
`pyproject.toml:[tool.poetry.group.test.dependencies]`
- commented out the `streamlit` from `collbacks/__init__.py`, It is
because now the `streamlit` requires Python >=3.7, !=3.9.7
- fixed duplicate names in `tools`
- fixed correspondent ut-s

Add the ability to run the map_reduce chains process results step as async (#6181)
This will add the ability to add an AsyncCallbackManager (handler) for
the reducer chain, which would be able to stream the tokens via the
`async def on_llm_new_token` callback method



Fixes # (issue)
[5532](https://github.com/hwchase17/langchain/issues/5532)


 @hwchase17  @agola11 
The following code snippet explains how this change would be used to
enable `reduce_llm` with streaming support in a `map_reduce` chain

I have tested this change and it works for the streaming use-case of
reducer responses. I am happy to share more information if this makes
solution sense.

Extend `ArgillaCallbackHandler` support (#6153)
Hi again @agola11! 🤗

## What's in this PR?

After playing around with different chains we noticed that some chains
were using different `output_key`s and we were just handling some, so
we've extended the support to any output, either if it's a Python list
or a string.

Kudos to @dvsrepo for spotting this!
