I just successfully compiled openCARP from source on an ubuntu machine, and I was trying to run the first tutorial 01_EP_single_cell/04_limpet_fe when I tried to execute using ./ when I got the following error.

e$ python3
Traceback (most recent call last):
  File "", line 403, in <module>
  File "/home/silvalab/.local/lib/python3.8/site-packages/carputils/", line 450, in wrapped
    prs = parser()
  File "", line 278, in parser
    parser = tools.standard_parser()
  File "/home/silvalab/.local/lib/python3.8/site-packages/carputils/", line 172, in standard_parser
    builds = tuple(settings.config.CARP_EXE_DIR.keys())
  File "/home/silvalab/.local/lib/python3.8/site-packages/carputils/settings/", line 48, in config
    self._config = config.load()
  File "/home/silvalab/.local/lib/python3.8/site-packages/carputils/settings/", line 173, in load
    fname = filename()
  File "/home/silvalab/.local/lib/python3.8/site-packages/carputils/settings/", line 121, in filename
    msg = NOSETTINGS_TEMPLATE.format('\n    - '.join(candidates))
TypeError: sequence item 0: expected str instance, NoneType found

Any suggestions on what the error might be would be very helpful.
