pytest reports PIO errors

[szwang1990]

Hi, I am new to xESMF and when I installed xESMF using conda on my PC following this tutorial, pytest reported 5 failed tests. I read about this issue, but in my case mpi, mpi4py and mpich packages are all there, then why does the PIO error still occur?

I put my conda list and the output of pytest -v --pyargs xesmf in the attachment.
