Going by the name of the demo you are trying to run: [Clamped semi-cylindrical Naghdi shell under point load — fenics-shells](https://fenics-shells.readthedocs.io/en/latest/demo/nonlinear-naghdi-cylindrical/demo_nonlinear-naghdi-cylindrical.py.html)
You should consider
[https://fenics-shells.github.io/fenicsx-shells/](https://fenics-shells.github.io/fenicsx-shells/)
For general FEniCSx demos see:

Please then state:
1. How did you install DOLFINx
in your other post ([Fenicsx 0.8 Installation Issues - #3 by Vivek](https://fenicsproject.discourse.group/t/fenicsx-0-8-installation-issues/15828/3)) you said it worked, so it is getting quite complicated to follow your issue

Yes Fenics is installed in my Ubuntu system.
I install the dolfinx by the following link “[GitHub - FEniCS/dolfinx: Next generation FEniCS problem solving environment](https://github.com/FEniCS/dolfinx/?tab=readme-ov-file#conda)” in this there is Ubuntu packages from there I install.
then I open the following link “[Demos — DOLFINx 0.8.0 documentation](https://docs.fenicsproject.org/dolfinx/v0.8.0/python/demos.html)”
and then I run the first demos example " [`demo_poisson.py`](https://docs.fenicsproject.org/dolfinx/v0.8.0/python/_downloads/b94ac7be61dc3726ca331afd20f195d2/demo_poisson.py)."
but when i run the following code then it show show that ModuleNotFoundError: No module named ‘dolfinx’.
and ModuleNotFoundError: No module named ‘dolfinx’
Please tell me procedure to solve .
Please

Please run
`python3 -m pip list` and `which python3` in your terminal to ensure that you are using the correct python.
Add the output of these commands here.

You have a super old version of dolfinx installed, definitely not 0.8.0.
