I have a tensor of some shape. I would like to select only n percentage of the elements in that tensor and add a number to them. For example, say I have a tensor like torch.tensor([1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0]) and I want to select n=.2 or 20% of the elements randomly then add 10. Then some possible results could be torch.tensor([10.0, 2.0, 3.0, 4.0, 15.0, 6.0, 7.0, 8.0, 9.0, 10.0]) 1st and 5th position chosen, or torch.tensor([1.0, 2.0, 3.0, 4.0, 5.0, 16.0, 7.0, 8.0, 9.0, 20.0]) 6th and 10th position chosen.
How can I do this for a tensor of an arbitrary shape? Then tensor is quite small and speed is not necessarily a top concern. Just want it to work. Thanks!
