## Installations
```Bash 
pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu117
pip install timm yacs spikingjelly termcolor opencv-python 
```

## Required Data
**"CIFAR10DVS"**: **spikingjelly** will download this dataset automatically.<br />
**"DVS128Gesture"**: Follow the **spikingjelly** instructions to download files manually.<br />
**"Other datasets"**: See [spikingjelly](https://spikingjelly.readthedocs.io/).

## Evaluation (switch to "master_with_checkpoints" branch)
⭐**CIFAR10DVS** **(top-1 acc. 84.8%)**
```Bash
python -m torch.distributed.launch --nproc_per_node 1 --master_port 23333 main.py \
--use_env --batch-size 64 --embed_split 24 --group_num 12 --patch_size 4 \
--data-path datasets/cifar10dvs --cfg configs/GET/GET_48.yaml --eval --resume checkpoints/GET_group12_cifar.pth
```
⭐**DVS128Gesture** **(top-1 acc. 97.9%)**
