I have a 1D Variable (LongTensor) and i want to find the indices of the elements with a given value (zero). Is there a way to do this efficiently in PyTorch?
For instance, in order to get the indices of non-zero elements, i do this:
non_zeros = torch.nonzero(lengths_c.view(-1).data).squeeze()
I need the opposite of this (indices of zero elements).
