Error while preparing dataset: ValueError: Couldn't cast schema because column names don't match

#1

I'm trying to load a dataset using the load_dataset function in Hugging Face's Datasets library, but I'm encountering an error when trying to prepare the dataset. Specifically, the error message says:

"ValueError: Couldn't cast schema because column names don't match"

This error seems to be related to the fact that the column names in the input data don't match the column names expected by the dataset builder. The error message suggests that there is a mismatch between the expected column names and the actual column names in the input data.

I'm not sure how to fix this error. Can anyone help me understand what might be causing it and how to resolve it?

Thank you in advance for your help!
