Witrynanumpy.transpose. #. Returns an array with axes transposed. For a 1-D array, this returns an unchanged view of the original array, as a transposed vector is simply the same vector. To convert a 1-D array into a 2-D column vector, an additional dimension must be added, e.g., np.atleast2d (a).T achieves this, as does a [:, np.newaxis] . WitrynaJ = imrotate (I,angle) rotates image I by angle degrees in a counterclockwise direction around its center point. To rotate the image clockwise, specify a negative value for angle. imrotate makes the output image J large enough to contain the entire rotated image. By default, imrotate uses nearest neighbor interpolation, setting the values of ... nancy garrett

Also, the output of make_grid is an image (in a tensor form of course) so in order to get this to work I had to simply convert it to numpy and transpose the axis so matplotlib can display it properly: new_img = torchvision.utils.make_grid(f).numpy().transpose(1,2,0) plt.imshow(new ... nancygchilders yahoo.com
