MPI_INIT failed

[ronaldolaishram]

While trying to run SEDfit_from_binmap
I got error always

here is the code snap

binid_range = [0,3]
fit_method = 'mcmc'
nwalkers = 100
nsteps = 600
nproc = 5

# Run fitting
SEDfit_from_binmap(
    fits_binmap, 
    binid_range=binid_range, 
    models_spec=models_spec, 
    params_ranges=params_ranges, 
    params_priors=params_priors,
    free_z=0, 
    gal_z=gal_z, 
    fit_method=fit_method, 
    nproc=nproc, 
    nwalkers=nwalkers, 
    nsteps=nsteps, 
    cosmo=0, 
    H0=70.0, 
    Om0=0.3,
    add_igm_absorption=add_igm_absorption, 
    igm_type=igm_type, 
    store_full_samplers=1
)

I always got
shmem: mmap: an error occurred while determining whether or not /var/folders/yx/7_4ythq14rxdl8zc8kbj0lyh0000gn/T//ompi.wlan-67-011.501/jf.0/2350448641/sm_segment.wlan-67-011.501.8c190001.0 could be created.
It looks like MPI_INIT failed for some reason; your parallel process is
likely to abort. There are many reasons that a parallel process can
fail during MPI_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):

PML add procs failed
--> Returned "Not found" (-13) instead of "Success" (0)

When I gave nproc=1, it says we need to have two.
why this happened
