np.shape() returns a 3d array, while cv2.getRotationMatrix2D() expects a 2d tuple for the center point.

you have to shave off the 3rd dimension (depth), to make it work:

center = tuple(np.array(image.shape)[:2]/2) # 2d ! rot_mat = cv2.getRotationMatrix2D(center,angle,1.0) result = cv2.warpAffine(image, rot_mat, image.shape,flags=cv2.INTER_LINEAR)
