[GRASS-user] grass-7.9 does not find numpy

[Rich Shepard]

Starting grass-7.9 in a new location and mapset fails:

wxnviz.py: This module requires the NumPy module, which could not be imported. It probably is not installed (it's not part of the standard Python distribution). See the Numeric Python site (http://numpy.scipy.org) for information on downloading source or binaries.

ImportError: No module named numpy

Numpy is installed (by pip) in /usr/lib64/python3.7/site-packages/.

Please advise me how to make this installation visible to wxnviz.
