VisibleDeprecationWarning: Using a non-integer instead of an integer will result in a future error

Question

When you run a python program that includes the following function, image[x,y] = 0 displays the following error message. What does this mean and how to solve it? Thanks.

A warning

 VisibleDeprecationWarning: using a non-integer number instead of an integer will result in an error in the future image[x,y] = 0 Illegal instruction (core dumped) 

the code

 def create_image_and_label(nx,ny): x = np.floor(np.random.rand(1)[0]*nx) y = np.floor(np.random.rand(1)[0]*ny) image = np.ones((nx,ny)) label = np.ones((nx,ny)) image[x,y] = 0 image_distance = ndimage.morphology.distance_transform_edt(image) r = np.random.rand(1)[0]*(r_max-r_min)+r_min plateau = np.random.rand(1)[0]*(plateau_max-plateau_min)+plateau_min label[image_distance <= r] = 0 label[image_distance > r] = 1 label = (1 - label) image_distance[image_distance <= r] = 0 image_distance[image_distance > r] = 1 image_distance = (1 - image_distance)*plateau image = image_distance + np.random.randn(nx,ny)/sigma return image, label[92:nx-92,92:nx-92]

A warning says not to use floats to index your array; use np.int instead of np.floor
