Can I call horovod training process in proc = subprocess.Popen(command, shell=True, cwd=cwd) using command

[bit-pku-zdf]

Environment:

1. Framework: tensorflow
2. Framework version:1.15
3. Horovod version:0.23.0
4. MPI version:
5. CUDA version:
6. NCCL version:
7. Python version:3.8.10
8. Spark / PySpark version:NO
9. Ray version:NO
10. OS and version:NO
11. GCC version:NO
12. CMake version:NO

Due to historical reasons, we need to use subprocess.Popen to call horovod + tf training process like,
subprocess.Popen("horovodrun -np 16 -H server1:4,server2:4,server3:4,server4:4 python train.py", shell=True, cwd=cwd)
Can I do this? Is there any problem with this?
Thank you
