Python: convert a 1-by-28-by-28 array to a 28-by-28 matrix -

i have grayscale image stored 1-by-28-by-28 array (uint8) wish display using matplotlib.

the relevant codes follows:

import matplotlib.pyplot plt  image = get_image() print image.shape    # prints (1, 28, 28) plt.imshow(image) 

this code results in typeerror: invalid dimensions image data.

to compatible imshow() need either squeeze array 28-by-28 (removing redundant dimension) or replicate 2d matrix (28-by-28) 3 (rgb) or 4 (rgba) channels.

my preference use first approach, squeeze() not remove redundant dimension.

how convert 1-by-28-by-28 array 28-by-28 matrix?

you can pass squeeze or reshape:

 imshow(np.squeeze(image))    imshow(image.reshape((28,28))
