How can I fix this?

[sphish]

Could you try running the nvshmem perftest to see if it works properly?

[Iamleos]

I met the same problem. This issue is usually caused by insufficient GPU memory. Try to reserve more GPU memory for DeepEP buffer

how to set this？

I met the same problem. This issue is usually caused by insufficient GPU memory. Try to reserve more GPU memory for DeepEP buffer我遇到了同样的问题。此问题通常是由 GPU 内存不足引起的。尝试为 DeepEP 缓冲区保留更多 GPU 内存

Log in to the physical machine and make sure that the memory on your GPU is not used by other processes.
