Nv_peer_mem driver was not detected

When I run “/usr/bin/nvidia_entrypoint.sh”(ngc 21.03), the following NOTE is displayed. Even if nv_peer_mem is set separately, it continues to appear. Does it keep happening because it will be deprecated soon?

NOTE: MOFED driver was detected, but nv_peer_mem driver was not detected. Multi-node communication performance may be reduced.

Are you seeing any other errors/warning before the MOFED warning?
Also, are you using multi-node training?
