About label format of GTA

[alphjheon]

@Chrisding @yzou2, what is the expected format of labels for GTA5 training, source only script? I used the labels.py script in order to transform themt o cityscapes format (valid labels 0-18) and the rest 255. Nevertheless, when i start training i got loss values with NaNs.

GTA5 and Cityscapes have the same label mapping function. For the NaN loss, one possible reason might be too large learning rate value. Also, I suggest you to post all your training script and we can give advices.
