Johnny Lee	0ab364404e	add continue to fix 'continue_on_failure' parameter for URL doc loader (#2735 ) Currently, the function still fails if `continue_on_failure` is set to True, because `elements` is not set. --------- Co-authored-by: leecjohnny <johnny-lee1255@users.noreply.github.com>	1 year ago
sergerdn	4bdcedab54	fix: some imports for integration tests (#2612 ) Add more missed imports for integration tests. Bump `pytest` to the current latest version. Fix `tests/integration_tests/vectorstores/test_elasticsearch.py` to update its cassette(easy fix). Related PR: https://github.com/hwchase17/langchain/pull/2560	1 year ago
Ankush Gola	c1521ddbdb	Add workaround for not having async vector store methods (#2733 ) This allows us to use the async API for the Retrieval chains, though it is not guaranteed to be thread safe.	1 year ago
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
vinoyang	8073bc849f	Minor: Remove duplicated word in error message (#2706 ) Removed the duplicated word "it" from the error message. From: `Please it install it with xxx` To: `Please install it with xxx`.	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
