Hey everyone,
could someone tell me the best way to get the indices of the first occurrences in a tensor along a specific dimension? By occurrence I mean the indices where the tensor is e.g. larger than a specific value:
For example, consider
my_tensor = torch.rand(10, 100)
my_value = 0.5

ind = (my_tensor < my_value) # Boolean mask whether the values are < 0.5

How do I obtain the first occurrence where ind == 1 along the dimension -1 (in a (10, 1) tensor) ?
For example, ind.nonzero() returns all non-zero values and does not keep the dimensions…
Thanks a lot!
