You won’t be able to reshape/view the input tensor of [16, 1024, 9, 9] into the shape [16, 1024, 13, 13], since the latter contains more elements.
However, you could use an interpolation method via e.g. nn.Upsample or F.interpolate or alternatively e.g. transposed convolution layers.
Let me know, if one of these approaches would work for you.
