Image data is represented in a three-dimensional array where the last channel represents the color channels, e.g. [rows] [cols] [channels]. Channels First. Witryna11 cze 2024 · To do so, we use the permute () function. import matplotlib.pyplot as plt plt.imshow(img_t.permute(1, 2, 0)) plt.show() We also may display t he label associated with the image: index_label The index_label variable is equal to 1. In fact we have retrieved the index that will allow us to know the name of the label.
