operands could not be broadcast together with shapes (19,20) (20,19)

Question

I'm trying to implement a wavelet fusion strategy using Python 3 and I have run into an error.

Here's what I have tried:

looking through similar problems on StackOverflow

Here's the code that generates the error:

    if (method == 'mean'):
        cooef = (cooef1 + cooef2) / 2
    elif (method == 'min'):
        cooef = np.minimum(cooef1,cooef2)
    elif (method == 'max'):
        cooef = np.maximum(cooef1,cooef2)
    else:
        cooef = []

Which line? What's the shape of the two arrays? Have tou read enough numpy basics to know what `broadcasting` means? — hpaulj, Aug 02 '21 at 18:52

Here you go:

cooef1 = np.random.randint(0,10,(19,20))
cooef2 = np.random.randint(0,10,(20,19))
np.maximum(cooef1,cooef2.T)
