• PyTorch or Caffe2: Pytorch
• How you installed PyTorch (conda, pip, source): pip
• OS: macos 10.13
• PyTorch version: 0.4.0
• Python version: 3.6.5

If I run this code in the interpreter,

import torch
t = torch.tensor([1, 2])
repr(t)

I get this output:

tensor([~1,~~2])

I put a ~ instead of a space for clarity. As you can see, extra spaces are printed. This happens even if I create a singleton 1D tensor.
