Problem when installing oasis

[Lauuragn]

Hello everyone!

I'm trying to install oasis in linux using Anaconda:

(fenicsx-env) [ana@ohpc Oasis]$ cd /gpfs/home/dyang/anaconda3/envs/fenicsx-env/bin/lib/python3.12/site-packages/oasis-2018.1-py3.12.egg/oasis/
(fenicsx-env) [ana@ohpc oasis]$ python NSfracStep.py problem=DrivenCavity solver=IPCS_ABCN
Traceback (most recent call last):
File "/gpfs/home/ana/anaconda3/envs/fenicsx-env/bin/lib/python3.12/site-packages/oasis-2018.1-py3.12.egg/oasis/NSfracStep.py", line 36, in
from oasis.common import *
ModuleNotFoundError: No module named 'oasis'

However, it cannot find the module named 'oasis', may be it's because inside the oasis folder there's not a file called oasis.py?
I'm struggling with the instalation if someone could help me.
The steps I'm following are:

1. I install fenics from this link: https://fenicsproject.org/download/
   conda create -n fenicsx-env
   conda activate fenicsx-env
   conda install -c conda-forge fenics-dolfinx mpich pyvista

2. Then I run

python setup.py install -- prefix = 'the path where i want Oasis installed'

3. Once it is supposed to be installed I tried to run as a test

The main modules NSfracStep.py and NSCoupled.py are executable and requires only that
the problem to be solved is added after the keyword problem, e.g.,
$ python NSfracStep.py problem=DrivenCavity solver=IPCS_ABCN
$ python NSCoupled.py problem=DrivenCavity element=TaylorHood
or the preferred way through Ipython
[ 1 ] run NSfracStep problem=DrivenCavity
[ 1 ] run NSCoupled problem=DrivenCavity element=TaylorHood

But, I get an error because it cannot find the "oasis" module

Thank you for your attention and your help!
