Thank,
I am running fedora28.
But, by default it run python2
Also under geany, it run pyhton2
even if I put
#!/usr/bin/python3
in my file
if I run python3 mypy.py
Then it run pyhton3
However, I get an error:
import matplotlib.pyplot as plt
ModuleNotFoundError: No module named 'matplotlib'
Do I need to install another matplotlib for python3?
I don't know: I haven't used any astropy packages, and suggested the
python3 version only because it seemed to tie in better with the
installation write-up. There;s a python2 set of packages as well, in an
apparently earlier version, which may be easier to set up. I'm stll
using f27...
