Python3 compatibility

Hi, @fvisin ,

Thanks for releasing this useful package. I followed the install instruction. However, when I import dataser_loaders, I got the following error in parallel_loader.py as the following. (Currently, I only need to load Camvid dataset)

Here is the setting in my config.ini

[camvid]
shared_path = /data/code/SegNet-Tutorial/

The Camvid dataset is located in the following folder structures (screen):

Hi @amiltonwong , thank you for checking out our framework.
Unfortunately we do not support python 3 at the moment. I don't know how long it would take to make it python 3 compatible, but unfortunately we don't plan to work on that in the near future at the moment.

Contributions in this direction are very welcome though, if you want to give it a try!
