i need you to fix the following code.
I expect that, given the 5 categories, if i select category_limit to 200, the onehot encoded file will ahve rows composed by image name and (200*5) columns for the one hot. if i select category limit to 50, i will have (50*5) columns.
it seems not the case. there are many more columns than there should be.

can you spot the error and fix it?

Please provide the full entire corrected script.
