ditafaith commented 1 year ago

Hi, I completed installed and try to runninh command test_okada.py, however, there is an error as follows,

ModuleNotFoundError: No module named 'DC3D' Is there any missing library ?

tbenthompson commented 1 year ago

Hi. Typically that means that either the installation failed or you're not using the same Python installation/virtualenv where you installed the package.

If you share a bit more info, I can try to help debug.

I use python 3.8 version and so far no problem with existing software use python. Is there any python library that must installed ?

The error is:

creating /usr/lib/python3.8/site-packages error: could not create '/usr/lib/python3.8/site-packages': Permission denied

You are failing to install the package because you are installing into your system Python installation and do not have permission to do that. sudo would help but you should also consider using a virtualenv or conda env

Hope that helps!

It's done, after perform sudo.
