pip install -r requirements.txt
python setup.py develop
- Refer to
./options/test
for the configuration file of the model to be tested, and prepare the testing data and pretrained model. - The pretrained models are available at Google Drive or Baidu Netdisk (access code: qyrl).
- Then run the follwing codes (taking
HAT_SRx4_ImageNet-pretrain.pth
as an example):
python hat/test.py -opt options/test/HAT_SRx4_ImageNet-pretrain.yml
The testing results will be saved in the ./results
folder.
Note that the tile mode is also provided for limited GPU memory when testing. You can modify the specific settings of the tile mode in your custom testing option by referring to ./options/test/HAT_tile_example.yml
.
- Refer to
./options/train
for the configuration file of the model to train. - Preparation of training data can refer to this page. ImageNet dataset can be downloaded at the official website.
- The training command is like
CUDA_VISIBLE_DEVICES=0,1,2,3,4,5,6,7 python -m torch.distributed.launch --nproc_per_node=8 --master_port=4321 hat/train.py -opt options/train/train_HAT_SRx2_from_scratch.yml --launcher pytorch
- Note that the default batch size per gpu is 4, which will cost about 20G memory for each GPU.
The training logs and weights will be saved in the ./experiments
folder.
The inference results on benchmark datasets are available at Google Drive or Baidu Netdisk (access code: 63p5).
