Witryna1 dzień temu · img = Image.fromarray (arr.astype (int), 'RGB') image = make_lupton_rgb (normalize1,normalize2,normalize3) plt.show (image) When I have done plot show in the code above, it just returned an empty graph with the x and y range I had set. I have also tried np.dstack, but it didn't seem to give data that made sense and the … WitrynaFor RGB and RGBA images, Matplotlib supports float32 and uint8 data types. For grayscale, Matplotlib supports only float32. If your array data does not meet one of these descriptions, you need to rescale it. Plotting numpy arrays as images # So, you have your data in a numpy array (either by importing it, or by generating it). Let's render it.
