ImportError: torch.utils.ffi is deprecated......

Hi all,

I met this problem and I have solved it by myself. I recorded here and hope it can help future users.

My PC uses Ubuntu 18.04. After installing the environment and downloading data, I got ' ImportError: torch.utils.ffi is deprecated... ' when running the main.py.

Possible cause: pytorch is 1.3 rather than 0.4.

Using conda list in the environment, I see pytorch is version 0.4. However, if I use python to import torch and print its version, it is 1.3!!!!

Long story short->
My guess: It seems that the pytorch install during 'conda env create -f environment.yml' has a name 0.4 but is actually 1.3.
My Solution: manually downloading from https://download.pytorch.org/whl/torch_stable.html and then install with pip under the virtual environment.
