Bagatur	5d60ced7b3	pydantic compatibility guide fix (#9418 )	1 year ago
Aashish Saini	ce78877a87	Replaced instances of raising ValueError with raising ImportError. (#9388 ) Refactored code to ensure consistent handling of ImportError. Replaced instances of raising ValueError with raising ImportError. The choice of raising a ValueError here is somewhat unconventional and might lead to confusion for anyone reading the code. Typically, when dealing with import-related errors, the recommended approach is to raise an ImportError with a descriptive message explaining the issue. This provides a clearer indication that the problem is related to importing the required module. @hwchase17 , @baskaryan , @eyurtsev Thanks Aashish --------- Co-authored-by: Bagatur <baskaryan@gmail.com>	1 year ago

Predrag Gruevski	8f2d321dd0	Cache .mypy_cache across lint runs. (#9405 ) Preserve the `.mypy_cache` directory across lint runs, to avoid having to re-parse all dependencies and their type information. Approximately a 1min perf win for CI.

Eugene Yurtsev	77b359edf5	More missing type annotations (#9406 ) This PR fills in more missing type annotations on pydantic models. It's OK if it missed some annotations, we just don't want it to get annotations wrong at this stage. I'll do a few more passes over the same files!	1 year ago
Predrag Gruevski	7e63270e04	Ensure the in-project venv gets cached in CI tests. (#9336 ) The previous caching configuration was attempting to cache poetry venvs created in the default shared virtualenvs directory. However, all langchain packages use `in-project = true` for their poetry virtualenv setup, which moves the venv inside the package itself instead. This meant that poetry venvs were not being cached at all. This PR ensures that the venv gets cached by adding the in-project venv directory to the cached directories list. It also makes sure that the cache key only includes the lockfile being installed, as opposed to all lockfiles (unnecessary cache misses) or just the top-level lockfile (cache hits when it shouldn't).	1 year ago

Predrag Gruevski	f2560188ec	Cache linting venv on CI. (#9342 ) Ensure that we cache the linting virtualenv as well as the pip cache for the `pip install -e langchain` step. This is a win of about 60-90s overall.

Joe Reuter	09aa1eac03	Airbyte loaders: Fix last_state getter (#9314 ) This PR fixes the Airbyte loaders when doing incremental syncs. The notebooks are calling out to access `loader.last_state` to get the current state of incremental syncs, but this didn't work due to a refactoring of how the loaders are structured internally in the original PR. This PR fixes the issue by adding a `last_state` property that forwards the state correctly from the CDK adapter. --------- Co-authored-by: Bagatur <baskaryan@gmail.com>	1 year ago

Jakub Kuciński	8bebc9206f	Add improved sources splitting in BaseQAWithSourcesChain (#8716 ) ## Type: Improvement --- ## Description: Running QAWithSourcesChain sometimes raises ValueError as mentioned in issue #7184: ``` ValueError: too many values to unpack (expected 2) Traceback: response = qa({"question": pregunta}, return_only_outputs=True) File "C:\Anaconda3\envs\iagen_3_10\lib\site-packages\langchain\chains\base.py", line 166, in __call__ raise e File "C:\Anaconda3\envs\iagen_3_10\lib\site-packages\langchain\chains\base.py", line 160, in __call__ self._call(inputs, run_manager=run_manager) File "C:\Anaconda3\envs\iagen_3_10\lib\site-packages\langchain\chains\qa_with_sources\base.py", line 132, in _call answer, sources = re.split(r"SOURCES:\s", answer) ``` This is due to LLM model generating subsequent question, answer and sources, that is complement in a similar form as below: ``` <final_answer> SOURCES: <sources> QUESTION: <new_or_repeated_question> FINAL ANSWER: <new_or_repeated_final_answer> SOURCES: <new_or_repeated_sources> ``` It leads the following line ``` re.split(r"SOURCES:\s", answer) ``` to return more than 2 elements and result in ValueError. The simple fix is to split also with "QUESTION:\s" and take the first two elements: ``` answer, sources = re.split(r"SOURCES:\s\|QUESTION:\s", answer)[:2] ``` Sometimes LLM might also generate some other texts, like alternative answers in a form: ``` <final_answer_1> SOURCES: <sources> <final_answer_2> SOURCES: <sources> <final_answer_3> SOURCES: <sources> ``` In such cases it is the best to split previously obtained sources with new line: ``` sources = re.split(r"\n", sources.lstrip())[0] ``` --- ## Issue: Resolves #7184 --- ## Maintainer: @baskaryan	1 year ago
