This project aims at providing the popular lightweight model implementations for real-time semantic segmentation.
## Usage
------
### Train
- **Single GPU training**
```
python train.py --model mobilenet --dataset citys --lr 0.01 --epochs 240
```
- **Multi-GPU training**
```
# for example, train mobilenet with 4 GPUs:
export NGPUS=4
python -m torch.distributed.launch --nproc_per_node=$NGPUS train.py --model mobilenet --dataset citys --lr 0.01 --epochs 240
```
### Evaluation
- **Single GPU evaluating**
```
python eval.py --model mobilenet_small --dataset citys
```
- **Multi-GPU evaluating**
```
# for example, evaluate mobilenet with 4 GPUs:
export NGPUS=4
python -m torch.distributed.launch --nproc_per_node=$NGPUS eval.py --model mobilenet --dataset citys
```
## Result
- **Cityscapes**
Where: `crop_size=768, lr=0.01, epochs=80`.
