remember to use torchtext==0.2.3

[wanghm92]

I tried running the preprocessing script after installing the latest torchtext, which seems to be incompatible by throwing this error:

***/torchtext/data/field.py", line 118, in Field torch.float32: float, AttributeError: 'module' object has no attribute 'float32'

Solved by referring to this post:

Hope it helps
