Evaluate

Pre-trained Cityscapes models available

Download and extract to weights directory.

Set evaluating = True inside config file (eg. configs/rn18_single_scale.py) and run:

python eval.py configs/rn18_single_scale.py

Train

python train.py configs/rn18_single_scale.py --store_dir=/path/to/store/experiments
