Hello there,

I have installed:
Installed /home/mrx/Documents/FEniCS/Oasis_MR-master/lib/python3.10/site-packages/oasis-2018.1-py3.10.egg
Processing dependencies for oasis==2018.1
Finished processing dependencies for oasis==2018.1

BUT when I run

python3 NSfracStep.py problem=DrivenCavity solver=IPCS_ABCN

I witness the error:
Traceback (most recent call last):
File "/home/mrx/Documents/FEniCS/Oasis_MR-master/oasis/NSfracStep.py", line 36, in
from oasis.common import *
ModuleNotFoundError: No module named 'oasis'
