[Bug]: llama3-405b-fp8 NCCL communication #7775
Comments
|
can you stably reproduce it? |
|
It's like this every time. After a few inferences, an error is reported, and the GPU usage rate is 100%. Currently, there is no problem with node inference 8b |
|
try |
Still Not work |
|
Have same issue, happens after model is running for a while. Startup arguments: |
|
same issue and solved by |
|
@TTTdas I think #8558 should fix it. can you have a try with the latest wheel? see https://docs.vllm.ai/en/latest/getting_started/installation.html#install-the-latest-code for installing the latest wheel. |
yes, it works! thx |

🐛 Describe the bug
目前在8 * A800上进行推理，vllm推理的40b fp8版本，然后tp=8，一开始能推理，试了几个case以后就通信异常了
