How do I split a list into equally-sized chunks? There are a number of ways to accomplish this, but the one I use is to make the x and y axes invisible (gets rid of the ticks) and also make the spines invisible (gets rid of the lines). case. I am working in the same location where the image is present, so I can just write the name of the image along with its extension. We can also visualize those images using the imshow function of the matplotlib library. In other words: the origin will coincide with the center of pixel (0, 0). correlation coefficient like Spearmans Turn off the axes.
