Illegal Instruction (core dumped) in installation

[bvhoof]

Hi,

When running the notebook, the inline plot function does not seem to be working any more.

openmc.plot_inline(plots)

results in a runtime error.

If I try to run openmc manually in plot mode from within the container, I get the following results:

usr@c1996b83cb0f:~/example_notebooks$ ls
MSRE.ipynb  geometry.xml  materials.xml  plots.xml
usr@c1996b83cb0f:~/example_notebooks$ openmc -p
 Reading cross sections XML file...
 Reading materials XML file...
 Reading geometry XML file...
Using the DOUBLE-DOWN interface to Embree.
Illegal instruction (core dumped)

Do you have any indication on what goes wrong here?

Also, I tried to compile the docker image myself, but I got stuck with versioning. See seperate issue & PR.

Thanks!
