Pytorch dependency

[jamieOverbeek]

After installing candle in a fresh conda environment with 'pip install git+https://github.com/ECP-CANDLE/candle_lib@develop', I try to import candle and get the following error:

import candle
Traceback (most recent call last):
File "", line 1, in
File "/homes/joverbeek/.conda/envs/candle_env/lib/python3.7/site-packages/candle/init.py", line 165, in

ModuleNotFoundError: No module named 'torch'

There was a logic error where a pytorch function was loaded outside the pytorch guard. It should be fixed as of a recent push
