Hi,
i am trying 3-us8k-cnn-extract-train but met with error at the section "Training on a minimised data set". hope you will help me to get out of this
this is what i got
fold1 features: (0, 60, 41, 2)
fold2 features: (0, 60, 41, 2)
fold3 features: (0, 60, 41, 2)

ValueError: Error when checking target: expected activation_4 to have shape (10,) but got array with shape (0,)
and it is craeting problem in later sections
I fixed it. I'll make a merge request.
