mpirun error in a docker environment

[Li-Lai]

@yjxiong Thanks for sharing the code. When use the training command, I met an openmp error. How to solve this problem?

It looks like orte_init failed for some reason; your parallel process is
likely to abort. There are many reasons that a parallel process can
fail during orte_init; some of which are due to configuration or
environment problems. This failure appears to be an internal failure;
here's some additional information (which may only be relevant to an
Open MPI developer):

orte_plm_base_select failed
--> Returned value Not found (-13) instead of ORTE_SUCCESS
