unable to import grizzly.grizzly

[sandeepsoman-rzt]

Hi,
I followed the instructions for Mac installation and ran setup.py for "pyweld" and "grizzly".
Importing grizzly.grizzly threw error for me since, inside the grizzly.py it was unable to import utils.py or seriesweld.py etc.
The imports worked once I manually changed the imports to --
"import grizzly.utils"
"import grizzly.seriesweld"
But now, it popped another error saying -
"dlopen(/usr/local/lib/python3.7/site-packages/grizzly/numpy_weld_convertor.dylib, 6): image not found"
This error also showed up for 'libweld.dylib' which was solved again by manually copying to the path.

I am getting the following error after running import grizzly:

import usb.core
ModuleNotFoundError: No module named 'usb'

Shouldn't this requirement be already present in the requirements.txt for grizzly ?
