Dear all, Was trying to run demo_navier-stokes.py using this: fenics@52eac62e9bc2:~/shared$ python3 ~/demo/python/documented/navier-stokes/demo_navier-stokes.py I have the below error message: Traceback (most recent call last): File “/home/fenics/demo/python/documented/navier-stokes/demo_navie…

This is a very general error message, and without showing what is in the path ../ it is impossible to give any guidance as to what is wrong.

[image] skyeagle: /demo/python/documented/navier-stokes/demo_navier-stokes.py” I am running a demo code in the documentation. find it here /demo/python/documented/navier-stokes/demo_navier-stokes.py” also here https://readthedocs.org/projects/fenics-containers/downloads/pdf/latest/

You need to clone the git repo with git lfs, see for instance: [image] Download repository: gzip error Did you do git lfs clone https://bitbucket.org/fenics-project/dolfin.git When I do the following: git lfs clone https://bitbucket.org/fenics-project/dolfin.git WARNING…

I do this git lfs clone Bitbucket inside Jupiter notebook or on the command prompt? when I do it on the command prompt I have: (fenicsx-env) franckm@Francks-MBP ~ % git lfs clone Bitbucket git: ‘lfs’ is not a git command. See ‘git --help’. The most similar command is log

See: How To Install git-lfs on Ubuntu 20.04 | Installati.one

I am using Mac OS. It is the same as on ubuntu?
