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](https://pandas.pydata.org/docs/reference/api/pandas.DataFrame.join.html).
