@albanD Well, this is awkward  how I missed it … and thanks a lot!
@apaszke I tried with t1[:,torch.LongTensor([1,3,4])] but no luck, error raised as
TypeError: indexing a tensor with an object of type LongTensor. The only supported types are integers, slices, numpy scalars and torch.LongTensor or torch.ByteTensor as the only argument.
My pytorch version is 0.1.10_2
