Scientific Linux 7.4: undefined symbol: ompi_mpi_logical8 error

Question

I am trying to run a Python Package that uses MPI for running tasks in parallel.

as per the package's guidelines; I installed MPICH 4.2.0, followed my mpi4py.

However, after running their example command, I get the following response:

Traceback (most recent call last):
  File "sGC_parameter_estimation.py", line 8, in <module>
    from mpi4py.futures import MPIPoolExecutor
  File "/home/people/hkaya/.local/lib/python3.6/site-packages/mpi4py/futures/__init__.py", line 20, in <module>
    from .pool import MPIPoolExecutor
  File "/home/people/hkaya/.local/lib/python3.6/site-packages/mpi4py/futures/pool.py", line 14, in <module>
    from . import _lib
  File "/home/people/hkaya/.local/lib/python3.6/site-packages/mpi4py/futures/_lib.py", line 20, in <module>
    from .. import MPI
ImportError: /home/people/hkaya/.local/lib/python3.6/site-packages/mpi4py/MPI.cpython-36m-x86_64-linux-gnu.so: undefined symbol: ompi_mpi_logical8

when I run "ldd" for the said .so file; here is the output:

ldd /home/people/hkaya/.local/lib/python3.6/site-packages/mpi4py/MPI.cpython-36m-x86_64-linux-gnu.so
    linux-vdso.so.1 =>  (0x00007ffefd45f000)

    libm.so.6 => /lib64/libm.so.6 (0x00002b8516a04000)

Although running -objdump -tT gives a very long list, where ompi_mpi_logical8 is included with an "UND" tag.

I also tried reinstalling mpi4py as suggested here, which did not resolve my issue. In fact, I noticed that mpi4py was installed in a different directory /usr/local/lib64/python3.6/site-packages from the one that the package was trying to import MPI from.

So, I am guessing that there is a clash between two mpi4py versions. But I cannot say for sure.

mpiexec --version gives two different outputs for when I am root vs not.

In root:

mpiexec (OpenRTE) 4.1.2

When I'm in my local home directory:

So, my question is: how can solve this contradiction?

Thanks in advance
