Hello,

I’m using ubuntu on a dual operating systems computer and I installed openmc using miniconda, I also have jupyter lab installed. When I try to import openmc I keep getting this error even though I activate the openmc env, what can I do?

Thank you everyone, I fixed it, I needed to run:  
conda run jupyter-lab from the openmc-env and it worked.
