Predrag Gruevski	ade683c589	Rely on `WORKDIR` env var to avoid ugly ternary operators in workflows. (#9456) ... Ternary operators in GitHub Actions syntax are pretty ugly and hard to read: `inputs.working-directory == '' && '.' || inputs.working-directory` means "if the condition is true, use `'.'` and otherwise use the expression after the `||`". This PR performs the ternary as few times as possible, assigning its outcome to an env var we can then reuse as needed.	11 months ago

Predrag Gruevski	8976483f3a	Lint only on the min and max supported Python versions. (#9450) ... Only lint on the min and max supported Python versions. It's extremely unlikely that there's a lint issue on any version in between that doesn't show up on the min or max versions. GitHub rate-limits how many jobs can be running at any one time. Starting new jobs is also relatively slow, so linting on fewer versions makes CI faster.	11 months ago

Predrag Gruevski	0dd2c21089	Do not bust `poetry install` cache when manually installing pydantic v2. (#9407) ... Using `poetry add` to install `pydantic@2.1` was also causing poetry to change its lockfile. This prevented dependency caching from working: - When attempting to restore a cache, it would hash the lockfile in git and use it as part of the cache key. Say this is a cache miss. - Then, it would attempt to save the cache -- but the lockfile will have changed, so the cache key would be *different* than the key in the lookup. So the cache save would succeed, but to a key that cannot be looked up in the next run -- meaning we never get a cache hit. In addition to busting the cache, the lockfile update itself is also non-trivially long, over 30s:  This PR fixes the problems by using `pip` to perform the installation, avoiding the lockfile change.	11 months 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>	11 months 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).	11 months ago

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>	11 months 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	11 months ago
