同样的步骤同样的环境我也是报这个错误

@hzzheng0612 @lianyant Have you installed NCCL? https://developer.nvidia.com/nccl

[luxinfeng]

Centos7 python3.10 CPU模式下也是这个报错，版本为0.7.0b1

Centos7 python3.10 CPU模式下也是这个报错，版本为0.7.0b1

我这边排查后发现是缺失OpenGL这几个库导致的，通过yum -y install epel-release \ && yum -y install mesa-libGL mesa-libGLU libXtst libXrender 补充上这几个依赖后就可以正常运行了

我安装了这个之后就正常了，非常感谢 @myhloli
