Try: (from https://matplotlib.org/3.3.3/tutorials/introductory/images.html)

import matplotlib.pyplot as plt

import matplotlib.image as mpimg
img = mpimg.imread('images.npy')

imgplot = plt.imshow(img[0])#plot the first -- notice you are trying to plot 20k images, not 1

You cannot plot a 4d array that way. Try to split the first dimension 20000 into individual RGB images and then plot them using plt.subplots instead.
