ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all() (couldnt figure out the solution)

I followed a CNN classification example on this link https://towardsdatascience.com/malware-classification-using-convolutional-neural-networks-step-by-step-tutorial-a3e8d97122f

I did look at the previous questions posted and i tried adding .any() and .all() on all numpy arrays that I can see but still couldn't solve the issue. What can I do?
