## 环境配置
在[光源](https://sourcefind.cn/#/service-list)可拉取推理的docker镜像。stable_diffusion_ait推荐的镜像如下：
```
docker pull image.sourcefind.cn:5000/dcu/admin/base/pytorch:2.1.0-ubuntu20.04-dtk24.04.1-py3.10
docker run -d -t -v /opt/hyhal:/opt/hyhal:ro --privileged --device=/dev/kfd --device=/dev/dri/ --network=host --group-add video --name sd-test image.sourcefind.cn:5000/dcu/admin/base/pytorch:2.1.0-ubuntu20.04-dtk24.04.1-py3.10
docker exec -it sd-test bash
source /opt/dtk/env.sh

pip3 install click timm 
pip3 install diffusers==0.11.1
```
