Hi,

data_parallel.py" uses the following import from pytorch:

from torch._utils import _unflatten_tensors

This function was recently removed with this commit so it is not possibly to run the code with the latest PyTorch version.

Ahh yes sorry, the old version of pytorch we used had some bugs with dataparallel.
v0.3.0 seems to have fixed them though.
Tentatively updated code to work with the most recent version.
Leaving this open for now. Let me know if it worked for you.

data_parallel.py was removed with 806e542, so I'm closing here :)
