I ran train.py and this is what I got

What could have went wrong?

Is this on your own dataset? The assertion error in data.py on line 103 seems to be the problem. Make sure you've set your number of classes to be equal to the list of classes in your dataset. If you can post more information about your dataset, I can probably help further.

you only need to fix assert len(label_hot) == len(self.classes) return label_hot as assert len(label_hot[0]) == len(self.classes) return label_hot[0] hope it works for you!

I am using your data and code, why is the same problem? i hope you answer.
