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
Hi ptrblck, thank you so much.
