WebI feel like PyTorch is lacking in that regard. gazorpazorpazorpazor • 2 yr. ago You could do some pointer magic. View as 1 dimensional, calculate the index as idx [0]*size (1)+idx [1], etc., and then use gather and scatter. torch.take is like gather_nd. scatter_nd you can accomplish with a sparse tensor and to_dense.
