Usage

Clone this repo

git clone https://github.com/nv-tlabs/GSCNN
cd GSCNN

Python requirements

Currently, the code supports Python 3

• numpy
• PyTorch (>=1.1.0)
• torchvision
• scipy
• scikit-image
• tensorboardX
• tqdm
• torch-encoding
• opencv
• PyYAML

Download pretrained models

Download the pretrained model from the Google Drive Folder, and save it in 'checkpoints/'

Download inferred images

Download (if needed) the inferred images from the Google Drive Folder

Evaluation (Cityscapes)

python train.py --evaluate --snapshot checkpoints/best_cityscapes_checkpoint.pth

Training

A note on training- we train on 8 NVIDIA GPUs, and as such, training will be an issue with WiderResNet38 if you try to train on a single GPU.
