Exploit the fact that, we reduce the unsqueeze operation to permute. ``` torch.all(torch.permute(x.unsqueeze(0), [1, 0, 2, 3]) == x.unsqueeze(1)) torch.all(torch.permute(x.unsqueeze(0), [1, 2, 0, 3]) == x.unsqueeze(2)) torch.all(torch.permute(x.unsqueeze(0), [1, 2, 3, 0]) == x.unsqueeze(3)) ``` This diff introduce a minor change to the Permute implementation that it no longer requires the input dimension length to match the length of the permute array. This allows the `unsqueeze` operation to achieve a no-op `unsqueeze(0)` and then apply a permute.
