Hello,
Thank you for reaching out and providing detailed information about the issue you're facing. The "list index out of range" error typically occurs when you're trying to access an index that doesn't exist in a list. In the context of the GooglePalm class in the LLM chain, this error could be caused by the following line of code:
return self.parse(result[0].text)If result is an empty list, and you're trying to access the first index, you'll get a "list index out of range" error.
To fix this issue, you could add a check to ensure that result is not empty before accessing its first index:
if result:
return self.parse(result[0].text)This will prevent the "list index out of range" error from occurring when result is an empty list.
As for the GooglePalm class, it is used to interact with Google's PaLM models for generating embeddings. It has several attributes and methods that can be configured to suit your needs. You can find more information about this class in the LangChain codebase.
Please try the suggested fix and let me know if it resolves your issue. If not, could you please provide more information about the inputs you're using when this error occurs? This will help me better understand the issue and provide a more accurate solution.
Best, Dosu
