Rounak Datta	7688bf9182	WhatsApp document loader - update regex (#2776 ) I was testing out the WhatsApp Document loader, and noticed that sometimes the date is of the following format (notice the additional underscore): ``` 3/24/23, 1:54_PM - +91 99999 99999 joined using this group's invite link 3/24/23, 6:29_PM - +91 99999 99999: When are we starting then? ``` Wierdly, the underscore is visible in Vim, but not on editors like VSCode. I presume it is some unusual character/line terminator. Nevertheless, I think handling this edge case will make the document loader more robust.	1 year ago

Matt Robinson	f0be3b0689	feat: add support for non-html in `UnstructuredURLLoader` (#2793 ) ### Summary Adds support for processing non HTML document types in the URL loader. For example, the URL loader can now process a PDF or markdown files hosted at a URL. ### Testing ```python from langchain.document_loaders import UnstructuredURLLoader urls = ["https://www.understandingwar.org/sites/default/files/Russian%20Offensive%20Campaign%20Assessment%2C%20April%2011%2C%202023.pdf"] loader = UnstructuredURLLoader(urls=urls, strategy="fast") docs = loader.load() print(docs[0].page_content[:1000]) ```	1 year ago
Tim Connors	e081c62aac	Fixed k=0 bug on ConversationBufferWindowMemory (#2796 ) Updated the "load_memory_variables" function of the ConversationBufferWindowMemory to support a window size of 0 (k=0). Previous behavior would return the full memory instead of an empty array.	1 year ago
dev2049	a094b7f807	Improve eval chain prompt (#2798 ) Eval chain is currently very sensitive to differences in phrasing, punctuation, and tangential information. This prompt has worked better for me on my examples. More general q: Do we have any framework for evaluating default prompt changes? Could maybe start doing some regression testing?	1 year ago

Joshua Snyder	59d054308c	Add type inference for output parsers (#2769 ) Currently, the output type of a number of OutputParser's `parse` methods is `Any` when it can in fact be inferred. This PR makes BaseOutputParser use a generic type and fixes the output types of the following parsers: - `PydanticOutputParser` - `OutputFixingParser` - `RetryOutputParser` - `RetryWithErrorOutputParser` The output of the `StructuredOutputParser` is corrected from `BaseModel` to `Any` since there are no type guarantees provided by the parser.

vr140	dd59193757	Remove unnecessary method from Qdrant vectorstore and clean up docstrings (#2700 ) Problem: The `from_documents` method in Qdrant vectorstore is unnecessary because it does not change any default behavior from the abstract base class method of `from_documents` (contrast this with the method in Chroma which makes a change from default and turns `embeddings` into an Optional parameter). Also, the docstrings need some cleanup. Solution: Remove unnecessary method and improve docstrings. --------- Co-authored-by: Vijay Rajaram <vrajaram3@gatech.edu>	1 year ago
Matthew Plachter	933dfac583	Add Zapier NLA OAuth access_token to be used (#2726 ) This change allows the user to initialize the ZapierNLAWrapper with a valid Zapier NLA OAuth Access_Token, which would be used to make requests back to the Zapier NLA API. When a `zapier_nla_oauth_access_token` is passed to the ZapierNLAWrapper it is no longer required for the `ZAPIER_NLA_API_KEY ` environment variable to be set, still having it set will not affect the behavior as the `zapier_nla_oauth_access_token` will be used over the `ZAPIER_NLA_API_KEY`	1 year ago

Johnny Lee	744c25cd0a	Updating YoutubeLoader.from_youtube_channel name and doc to reflect actual usage (#2734 ) the function actually updates video_id from URL not channel.

vowelparrot	0806951c07	Update VectorStore Class Method Typing (#2731 ) Avoid using placeholder methods that only perform a `cast()` operation because the typing would otherwise be inferred to be the parent `VectorStore` class. This is unnecessary with TypeVar's.	1 year ago
Adam McCabe	446c3d586c	Add PATCH and DELETE to OpenAPI Agent (#2729 ) This PR proposes an update to the OpenAPI Planner and Planner Prompts to make Patch and Delete available to the planner and executor. I followed the same patterns as for GET and POST, and made some updates to the examples available to the Planner and Orchestrator. Of note, I tried to write prompts for DELETE such that the model will only execute that job if the User specifically asks for a 'Delete' (see the Prompt_planner.py examples to see specificity), or if the User had previously authorized the Delete in the Conversation memory. Although PATCH also modifies existing data, I considered it lower risk and so did not try to enforce the same restrictions on the Planner.	1 year ago

134ARG	1e60e6e15b	Fix the unset argument in calling llama model (#2714 ) When using the llama.cpp together with agent like zero-shot-react-description, the missing branch will cause the parameter `stop` left empty, resulting in unexpected output format from the model. This patch fixes that issue.	1 year ago
Joshua Snyder	f435f2267c	Use tiktoken for Python 3.8 (#2709 ) Fixes issue #2677 `tiktoken` is supported for Python 3.8, so there is no need to use the fallback GPT-2 tokenizer.	1 year ago
Kei Kamikawa	186ca9d3e4	fixed aiohttp.client_exceptions.ClientConnectionError: Connection closed (#2718 ) I fixed an issue where an error would always occur when making a request using the `TextRequestsWrapper` with async API. This is caused by escaping the scope of the context, which causes the connection to be broken when reading the response body. The correct usage is as described in the [official tutorial](https://docs.aiohttp.org/en/stable/client_quickstart.html#make-a-request), where the text method must also be handled in the context scope. <details> <summary>Stacktrace</summary> ``` File "/home/vscode/.cache/pypoetry/virtualenvs/codehex-workspace-xS3fZVNL-py3.11/lib/python3.11/site-packages/langchain/tools/base.py", line 116, in arun raise e File "/home/vscode/.cache/pypoetry/virtualenvs/codehex-workspace-xS3fZVNL-py3.11/lib/python3.11/site-packages/langchain/tools/base.py", line 110, in arun observation = await self._arun(tool_input) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/vscode/.cache/pypoetry/virtualenvs/codehex-workspace-xS3fZVNL-py3.11/lib/python3.11/site-packages/langchain/agents/tools.py", line 22, in _arun return await self.coroutine(tool_input) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/vscode/.cache/pypoetry/virtualenvs/codehex-workspace-xS3fZVNL-py3.11/lib/python3.11/site-packages/langchain/chains/base.py", line 234, in arun return (await self.acall(args[0]))[self.output_keys[0]] ^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/vscode/.cache/pypoetry/virtualenvs/codehex-workspace-xS3fZVNL-py3.11/lib/python3.11/site-packages/langchain/chains/base.py", line 154, in acall raise e File "/home/vscode/.cache/pypoetry/virtualenvs/codehex-workspace-xS3fZVNL-py3.11/lib/python3.11/site-packages/langchain/chains/base.py", line 148, in acall outputs = await self._acall(inputs) ^^^^^^^^^^^^^^^^^^^^^^^^^ File "/workspace/src/tools/example.py", line 153, in _acall api_response = await self.requests_wrapper.aget("http://example.com") ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/vscode/.cache/pypoetry/virtualenvs/codehex-workspace-xS3fZVNL-py3.11/lib/python3.11/site-packages/langchain/requests.py", line 130, in aget return await response.text() ^^^^^^^^^^^^^^^^^^^^^ File "/home/vscode/.cache/pypoetry/virtualenvs/codehex-workspace-xS3fZVNL-py3.11/lib/python3.11/site-packages/aiohttp/client_reqrep.py", line 1081, in text await self.read() File "/home/vscode/.cache/pypoetry/virtualenvs/codehex-workspace-xS3fZVNL-py3.11/lib/python3.11/site-packages/aiohttp/client_reqrep.py", line 1037, in read self._body = await self.content.read() ^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/vscode/.cache/pypoetry/virtualenvs/codehex-workspace-xS3fZVNL-py3.11/lib/python3.11/site-packages/aiohttp/streams.py", line 349, in read raise self._exception aiohttp.client_exceptions.ClientConnectionError: Connection closed ``` </details>	1 year ago
