Description
跑的是简单改动后的run-qwen3-4B.sh(只改了文件路径那种配置)，出现下列问题。
两个可能有用的debug信息：
- colocate会报错，不colocate就没问题
- 之前跑通过完全一样的script，前后diff在：换了个集群 & 更新了代码(pull前应该是10.1之前的版本)
求大佬帮看看，谢谢！

Research direction
Start with run-qwen3-4B.sh and inspect the colocate path that creates or destroys process groups. Reproduce the failure with colocate enabled, then compare the working and failing cluster and code versions described in the issue. Done means identifying the incompatible process-group configuration and confirming that the script completes without the ValueError.
