Hi, just put your slices in a tuple and it will work:
>>> x = torch.arange(0, 25).view(5, 5)
  0   1   2   3   4
  5   6   7   8   9
 10  11  12  13  14
 15  16  17  18  19
 20  21  22  23  24
[torch.FloatTensor of size 5x5]

>>> slicers=(slice(0,2), slice(0,2))
>>> x[slicers]
 0  1
 5  6
[torch.FloatTensor of size 2x2]
