Issues on evaluation process

[uyoung-jeong]

Thanks for the great work!

I wanted to leave issues while I was running the evaluation code.

PARE/scripts/eval.py

Line 39 in fa90aff

hparams.DATASET.NUM_WORKERS = -1 # set this to be compatible with other machines

num_workers=-1 raises an error in my machine as below:
ValueError: num_workers option should be non-negative; use num_workers=0 to disable multiprocessing.

num_workers=0 resolves the issue.

In order to use jpeg4py module smoothly, I had to install libturbojpeg using the following command:
sudo apt-get install libturbojpeg
You might not have noticed this dependency yet, since it's not a python module.
