Generate submission section,
I have found an error while running the code to ‘‘get the image features for the test set’’. The Code and Error details are given below.

Code:
test_features = submission_format.join(image_features, how=“left”, validate=“1:1”)

TypeError: join() got an unexpected keyword argument ‘validate’

You have an older version of pandas then, docs say that argument was added in 1.5, pandas.DataFrame.join — pandas 1.5.3 documentation.
