- pyquickhelper.pycode.tkinter_helper.fix_tkinter_issues_virtualenv(exc=True, fLOG=None)[source]¶
Fix an issue which happens in a virtual environment, see Fix Tcl inside a virtualenv on Windows

fLOG – logging function

list of environment variables
We try to deal with the following issue on Linux:
_tkinter.TclError: no display name and no $DISPLAY
On Linux, the solution is to run:
import matplotlib as mpl mpl.use('Agg')
But it does not work if matplotlib was already imported. It is recommended to delay its import whenever it is possible.
