Openmc spack installation

I want to launch a depletion simulation using HPC cluster with spack installation of openmc but i get this message error:
File “/data/o.jai/spack/var/spack/environments/spack_openmc/.spack-env/view/lib/python3.10/site-packages/openmc/material.py”, line 294, in Material
def from_hdf5(cls, group: h5py.Group):
AttributeError: module ‘h5py’ has no attribute ‘Group’

I want some idea or sample script to run a spack openmc for a depletion simulation with mpi(openmpi).

Regards
