I have 8 gpus on my machine. When starting the server, this warning message is printed. How does this mean?

Hi @frankxyy ,

Please share the full error log for more info/context if you need more information.

Assuming this warning is coming from TensorFlow, see this post: https://stackoverflow.com/a/43946365

It should not cause any errors, this warning just means communication between GPUs may be slower than on a system with P2P capabilities. You can also see the output of nvidia-smi topo -m for more information on the GPU topology for your system.
