for training 2x network

[Rainyliuliu]

Hello, for training 2x network ,i change your code in self.upscale4x = nn.Sequential( nn.Conv2d(in_channels=64, out_channels=256, kernel_size=3, stride=1, padding=1, bias=False), nn.PixelShuffle(2), nn.LeakyReLU(0.2, inplace=True), #nn.Conv2d(in_channels=64, out_channels=256, kernel_size=3, stride=1, padding=1, bias=False), #nn.PixelShuffle(2), #nn.LeakyReLU(0.2, inplace=True), )

while my test result is similiar with 4x network , could you give me some suggest?
