This time I will bring you Python method to output two-dimensional array to picture, Python outputs two-dimensional array to of the picture What are the precautions? The following is a practical case, let’s take a look.

For a two-dimensional array, img_mask

[[ 0 0 0 ..., 7 7 7]
 [ 0 0 0 ..., 7 7 7]
 [ 0 0 0 ..., 7 7 7]
 ..., 
 [266 266 266 ..., 253 253 253]
 [266 266 266 ..., 253 253 253]
 [266 266 266 ..., 253 253 253]]

The code displayed as a picture is:

import matplotlib.pyplot as pyplot 
pyplot.imshow(im_mask)
