For example, mask = y[y==certain_class] new_y = mask * y

It has an error in line new_y = mask * y, the error is new_y = mask * y ValueError: operands could not be broadcast together with shapes (12518,) (21025,3)

SSRN/Classification Maps/IN_classification_maps.py

Line 189 in f6ee47e

x = np.ravel(pred_test_conv1)

Use the following snipt after the above line:
mask = x[x==certain_class]
x= mask * x

[Aaron1993]

There is the same error in x=mask * x, whether certain_class is the class number, for example certain_class==1?

[zilongzhong]

Yes, you can select which class to show.

But the error x = mask * x ValueError: operands could not be broadcast together with shapes (12518,) (21025,3) show in this line.

You can use print (x.shape) to make sure x is a one-dimension vector debug the issue, and get rid of the lines of "mask = y[y!=certain_class]; new_y = mask * y". Then, updated the snippet as follows: mask = -1 * x[x!=certain_class] x= mask * x
