ConvTranspose2d Weight Shape

I have a question about ConvTranspose2d.weight shape. As mentioned in the PyTorch documentation the shape of ConvTranspose2d.weight tensor is as follows: (in_channels, out_channels​, kernel_size[0], kernel_size[1]) Note that I have omitted the groups parameter in the above shape. Now, my question is that why not its shape as follows? (out_channels, in_channels, kernel_size[0], kernel_size[1]) My problem related to the position of (in_channels, out_channels). As in some resources the Transpo…
