ValueError: mpi4py.MPI.Datatype size changed, may indicate binary incompatibility

[hmcezar]

I'm trying to use PyZoltan in an environment with mpich and I'm getting the error:

Python 3.10.0 (default, Mar  3 2022, 09:58:08) [GCC 7.5.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from pyzoltan.core import zoltan
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "pyzoltan/core/zoltan.pyx", line 1, in init pyzoltan.core.zoltan
ValueError: mpi4py.MPI.Datatype size changed, may indicate binary incompatibility. Expected 40 from C header, got 32 from PyObject

If I create a new environment from the .yml file provided in the repository, things works, so I suspect the problem might be I'm using mpich.
I tried reinstalling and downgrading mpi4py without any success.
Any ideas on how to solve this?

I'm attaching a file containing all the packages installed in my environment.
