I follow the manual to install sfepy in a conda environment.
The tests I made (python ./run_tests.py) are ok except this error which does exist for several test files :
PETSc Error --- Open MPI library version
Open MPI v4.1.0, package: Open MPI runner(a)Mac-1610582404968.local Distribution, ident: 4.1.0, repo rev: v4.1.0, Dec 18, 2020 does not match what PETSc was compiled with 4.0, aborting
--- test_eigenvalue_solvers: failed!
An idea ?
