Exception: Error when checking target: expected rpn_out_class to have shape (None, None, None, 12) but got array with shape (1, 19, 25, 24)

hi, when I used the code and dataset, I encountered this problem: "Exception: Error when checking target: expected rpn_out_class to have shape (None, None, None, 12) but got array with shape (1, 19, 25, 24)".

What should I do?

I change my keras version from keras 2.1.1 to keras 2.0.9，it works fine for me
