Problem description

ERROR: Cannot install -r requirements.txt (line 1), -r requirements.txt (line 6) and torch==2.0.0 because these package versions have conflicting dependencies.

The conflict is caused by:
    The user requested torch==2.0.0
    deepspeed 0.9.2 depends on torch
    xformers 0.0.20 depends on torch==2.0.1

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

ERROR: ResolutionImpossible: for help visit https://pip.pypa.io/en/latest/topics/dependency-resolution/#dealing-with-dependency-conflicts

后面我把torch的指定版本去掉，直接装最新的，可以跑

后续我们会提供一个conda-recipe，近期会更新在README中。

装都装不上 这个安装过程 太难嘞。
