'opal_shmem_base_select failed' on Linux

try to run mpi using conda on Ubuntu 20.04.3 but failed with:

--------------------------------------------------------------------------
It looks like opal_init failed for some reason; your parallel process is
likely to abort.  There are many reasons that a parallel process can
fail during opal_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):

  opal_shmem_base_select failed
  --> Returned value -1 instead of OPAL_SUCCESS
--------------------------------------------------------------------------

created environment with

conda create -n ENV_NAME -c conda-forge 'python=3.10.*' openmpi mpi4py,

could anyone provide some help on this?

Besides, attach the bash scripts to solve this issue incase somebody want to have a try

$ sudo apt-get update                 # upgrade apt-get to latest
$ sudo apt-get -y install mpich       # install mpich
$ sudo apt-get -y install openmpi-bin # install openmpi
$ sudo pip install mpi4py             # install mpi4py
$ find / -name libmpi.so              # find the relevant mpi lib on your machine
$ export LD_PRELOAD=path/to/your/libmpi.so
$ source ~/.bashrc                     # add to bash profile
$ export OMPI_ALLOW_RUN_AS_ROOT=1
$ export OMPI_ALLOW_RUN_AS_ROOT_CONFIRM=1
$ source ~/.bashrc                    # add to bash profile
$ mpiexec --help                      # return the following if success
mpiexec (OpenRTE) 4.0.5
