updating silent integer division

[vincentqb]

pytorch is changing its behavior with respect to integer division, e.g. #888. Has any other instances occurred?

Once the error below has been resolved, we can close this issue if no other occurrence is raised.

RuntimeError: Integer division of tensors using div or / is no longer supported, and in a future release div will perform true division as in Python 3. Use true_divide or floor_divide (// in Python) instead.
