xampl0{1-5}.py not working

[f-dangel]

Hey,

I set up the conda environment as described in the README. The examples don't seem to work out of the box, though. Here is a summary:

• python xmpl01.py

    AttributeError: 'Box' object has no attribute 'boxes_stored'

• python xmpl02.py

    AttributeError: 'Box' object has no attribute 'boxes_stored'

• python xmpl03.py

    ModuleNotFoundError: No module named 'Base.bp2DAction'

• python xmpl04.py

    ImportError: attempted relative import with no known parent package

• python xmpl05.py

    ImportError: attempted relative import with no known parent package
