WARNING about DeepMD-kit： dp train

[walkjoker-c]

I configured a workstation with an RTX3090, installed centos Linux system and graphics card driver: NVIDIA-Linux-x86_64-470.63.01, I did not install any other software. I downloaded deepMD-kit and used the DP train command.

DPMD-kit version: deepmd-kit-2.0.0.b4-cuda11.3_gpu-Linux-x86_64.sh

Program warning :
WARNING:deepmd.train.run_options:Switch to serial execution due to lack of horovod module.

The training program is running normally. After Google, I learned that serial execution is inefficient. Do I get this program warning because I only have one GPU? What is the solution to switching to parallel execution mode
