Import Error: cannot import name 'Module'

In my case I try to run the den-texture encoding network
My environment is : on the computer is cuda 10 without cudnn

and after python setup.py install then run the python prepare_minc.py it said

python scripts/prepare_minc.py
Traceback (most recent call last):

Start by running scripts/prepare_minc.py in the reported Python environment and read encoding/nn/encoding.py, especially its torch.nn import. Trace the installed encoding package and PyTorch versions; the issue is done when prepare_minc.py starts without the reported ImportError.
