I understand that you're encountering a UnicodeDecodeError
when trying to load a CSV file using the CSVLoader in LangChain. This error typically occurs when the file contains characters that aren't recognized by the default encoding, which in this case is 'utf-8'.
To address this issue, you can specify the encoding when initializing the CSVLoader. If you're unsure of the file's encoding, you can try using 'latin1', 'iso-8859-1', or 'cp1252'. Here's how you can adjust your code:
loader = CSVLoader(file_path="profiles.csv", source_column="IdentityId", encoding='latin1')
doc = loader.load()
Please replace 'latin1' with the correct encoding if it's different. If you're unsure of the correct encoding, you may need to experiment with a few different ones to see which one works.
This solution assumes that the error is due to an encoding issue. However, if the error persists after trying different encodings, there might be other factors at play.
If you believe this is a bug that could impact other users, feel free to make a pull request with a proposed fix. We appreciate contributions from our user community.
Also, if you're using an older version of LangChain, I would recommend upgrading to the latest version as this might resolve your issue if it was due to a bug that has since been fixed.

I experience the same issue.
Pandas reads the file with defualt settings (utf-8
), but CSVLoader
fails wih UnicodeDecodeError
not sure why the bot suggests encoding latin, did that fixed it for you @AlxndrMlk
Hi @levalencia
I changed the encoding to 8859
and it worked.
That said, I am still not sure what caused the error as pandas
opens the same file without issues.
I also saved the file from pandas
explicitly specifying utf-8
as encoding and tried to re-read with the CSVLoader
, but it did not solve the issue.
Hi, @levalencia! I'm Dosu, and I'm helping the LangChain team manage their backlog. I wanted to let you know that we are marking this issue as stale.
From what I understand, you encountered a UnicodeDecodeError when trying to load a CSV file using the CSVLoader. It seems that specifying the encoding as 'latin1' or '8859' resolved the issue for other users. However, it's unclear what caused the original problem.
Before we close this issue, we wanted to check if it is still relevant to the latest version of the LangChain repository. If it is, please let us know by commenting on this issue. Otherwise, feel free to close the issue yourself or it will be automatically closed in 7 days.
Thank you for your understanding!
