Hi All,
I met the following probem.

jiadun@jiadun-HP-ZBook-15:~$ yade
Welcome to Yade 2019.01a 
TCP python prompt on localhost:9000, auth cookie `ksyasu'
XMLRPC info provider on http://localhost:21000
[[ ^L clears screen, ^U kills line. F12 controller, F11 3d view (use h-key for showing help), F10 both, F9 generator, F8 plot. ]]

Yade [1]: from mpi4py import *

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_error_register failed
  --> Returned value -2 instead of OPAL_SUCCESS

[jiadun-HP-ZBook-15:3988] Local abort before MPI_INIT completed successfully; not able to aggregate error messages, and not able to guarantee that all other processes were killed!
