Any import that touches langchain.retrievers currently requires Lark.
Here's one attempt to fix. Not very pretty, very open to other ideas.
Alternatives I thought of are 1) make Lark requirement, 2) put
everything in parser.py in the try/except. Neither sounds much better
Related to #4316, #4275
Fixed two small bugs (as reported in issue #1619 ) in the filtering by
metadata for `chroma` databases :
- ```langchain.vectorstores.chroma.similarity_search``` takes a
```filter``` input parameter but do not forward it to
```langchain.vectorstores.chroma.similarity_search_with_score```
- ```langchain.vectorstores.chroma.similarity_search_by_vector```
doesn't take this parameter in input, although it could be very useful,
without any additional complexity - and it would thus be coherent with
the syntax of the two other functions.

Currently, MultiPromptChain instantiates a ChatOpenAI LLM instance for
the default chain to use if none of the prompts passed match. This seems
like an error as it means that you can't use your choice of LLM, or
configure how to instantiate the default LLM (e.g. passing in an API key
that isn't in the usual env variable).
Fixes#4153
If the sender of a message in a group chat isn't in your contact list,
they will appear with a ~ prefix in the exported chat. This PR adds
support for parsing such lines.
# Add support for Qdrant nested filter
This extends the filter functionality for the Qdrant vectorstore. The
current filter implementation is limited to a single-level metadata
structure; however, Qdrant supports nested metadata filtering. This
extends the functionality for users to maximize the filter functionality
when using Qdrant as the vectorstore.

This pr makes it possible to extract more metadata from websites for
later use.
my usecase:
parsing ld+json or microdata from sites and store it as structured data
in the metadata field
- added `Wikipedia` retriever. It is effectively a wrapper for
`WikipediaAPIWrapper`. It wrapps load() into get_relevant_documents()
- sorted `__all__` in the `retrievers/__init__`
- added integration tests for the WikipediaRetriever
- added an example (as Jupyter notebook) for the WikipediaRetriever
# Minor Wording Documentation Change
```python
agent_chain.run("When's my friend Eric's surname?")
# Answer with 'Zhu'
```
is change to
```python
agent_chain.run("What's my friend Eric's surname?")
# Answer with 'Zhu'
```
I think when is a residual of the old query that was "When’s my friends
Eric`s birthday?".
# Add PDF parser implementations
This PR separates the data loading from the parsing for a number of
existing PDF loaders.
Parser tests have been designed to help encourage developers to create a
consistent interface for parsing PDFs.
This interface can be made more consistent in the future by adding
information into the initializer on desired behavior with respect to splitting by
page etc.
This code is expected to be backwards compatible -- with the exception
of a bug fix with pymupdf parser which was returning `bytes` in the page
content rather than strings.
Also changing the lazy parser method of document loader to return an
Iterator rather than Iterable over documents.

# Add MimeType Based Parser
This PR adds a MimeType Based Parser. The parser inspects the mime-type
of the blob it is parsing and based on the mime-type can delegate to the sub
parser.
## Before submitting
Waiting on adding notebooks until more implementations are landed.

# Fix grammar in Text Splitters docs
Just a small fix of grammar in the documentation:
"That means there two different axes" -> "That means there are two

Add a notebook in the `experimental/` directory detailing:
- How to capture traces with the v2 endpoint
- How to create datasets
- How to run traces over the dataset

This PR adds:
* Option to show a tqdm progress bar when using the file system blob loader
* Update pytest run configuration to be stricter
* Adding a new marker that checks that required pkgs exist
- Update the load_tools method to properly accept `callbacks` arguments.
- Add a deprecation warning when `callback_manager` is passed
- Add two unit tests to check the deprecation warning is raised and to
confirm the callback is passed through.
Closes issue #4096
This commit adds support for passing binary_location to the SeleniumURLLoader when creating Chrome or Firefox web drivers.
This allows users to specify the Browser binary location which is required when deploying to services such as Heroku
This change also includes updated documentation and type hints to reflect the new binary_location parameter and its usage.
fixes#4304
Today, when running a chain without any arguments, the raised ValueError
incorrectly specifies that user provided "both positional arguments and
keyword arguments".
This PR adds a more accurate error in that case.
Related: #4028, I opened a new PR because (1) I was unable to unstage
mistakenly committed files (I'm not familiar with git enough to resolve
this issue), (2) I felt closing the original PR and opening a new PR
would be more appropriate if I changed the class name.
This PR creates HumanInputLLM(HumanLLM in #4028), a simple LLM wrapper
class that returns user input as the response. I also added a simple
Jupyter notebook regarding how and why to use this LLM wrapper. In the
notebook, I went over how to use this LLM wrapper and showed example of
testing `WikipediaQueryRun` using HumanInputLLM.
I believe this LLM wrapper will be useful especially for debugging,
educational or testing purpose.
