a = torch.IntTensor([1,3,2,1,4,2])
b=[2,1,6]
I want to find index of values in list b, with the result index sorted
like output as  tensor([0, 2, 3, 5])
I know how to do it separately:
torch.nonzero(a == 1).squeeze_(1)
–>tensor([0, 3])
torch.nonzero(a == 2).squeeze_(1)
–>tensor([2, 5])
torch.nonzero(a == 6).squeeze_(1)
–>tensor([], dtype=torch.int64)
but how can I do it at once? or in a better way.
Thanks.
