When I try to build it, it tells me byte is not a type identifier.
My code is as follow, what am I doing wrong?
def fitness(int new_image, int original_image, int size):
cdef byte *new_pixels = <byte*><Py_ssize_t>size
cdef byte *original_pixels = <byte*><Py_ssize_t>size
cdef long spam = 0
cdef int i = 0
for i in range(len(new_pixels)):
spam += abs(original_pixels[i] - new_pixels[i])
return 1020 * len((original_pixels)) - spam
