Hi, I want to convert the grayscale of MNIST images to RGB as its values are between 0 and 255. How is it possible for PyTorch?
To create the RGB channels, you could either repeat the gray channel manually or use transforms.Grayscale(num_output_channels=3)
. I’m not sure if you want to yield tensors in the range [0, 255]
, but if so you could use transforms.Normalize(mean=0., std=(1/255., 1/255., 1/255.))
after applying transforms.ToTensor()
.
