Hyperion-rt Python Package OSError

Question

I need to use the hyperion package for python (http://docs.hyperion-rt.org/en/stable/index.html, the three-dimensional dust continuum Monte-Carlo radiative transfer code, not the hyperion by Oracle!). I installed it and already solved the known error of the wrong import in some of the files (the import six line). I also created the dust file and have a script for the model.

So now it should be running successfully. Unfortunately, it does not run and gives me the following error:

OSError: Unable to open file (unable to open file)

Process finished with exit code 1

I tried to search for solutions online and asked some coworkers, but unfortunately can not find any solution. I also can not even find the path in the last mentioned part (the .../_hl/... path) in my computer.

If that is important: I use Ubuntu.

Anyone any idea or hint on how I could solve it?

Thank you in advance!
