Traceback (most recent call last):

im.convolve(kernel)

self.convolveH(np.array(self.image),kernel)

newvalue+=matrix[yind][xind]*kernel[ky][kx]
IndexError: only integers, slices (:), ellipsis (...), numpy.newaxis (None) and integer or boolean arrays are valid indices

Facing this error, please help me debug this. Thanks!
