包版本问题，环境到底该怎么装？

[zhangjy328]

为什么readme安装写的timm==0.8.15dev0？？这是什么意思，environment.yaml里写的timm==0.6.12？？按照readme安装环境，报错Could not find a version that satisfies the requirement timm==0.8.15dev0，还有很多包版本都不一致，按照哪个装环境啊？？

xFormers was built for: PyTorch 2.0.0, but environment.yaml--dependencies--pytorch=1.12.1???

I apologize for any inconvenience caused. The correct version of timm should be timm==0.8.15dev0. Installing xFormers is optional; if you install xFormers, you need torch==2.0.0. Otherwise, torch==1.12.1 can also run properly.
