Fedora23 tweak tool does not work solution

Failed to open the optimizer tool in the launcher

Turn on the display in the terminal

Traceback (most recent):   " /usr/bin/gnome-tweak-tool "  in <module>    import'gtweak'

Fedora default Python is python3, some old programs are used Python2

Guess is this caused the problem will/usr/bin/gnome-tweak-tool in the first line

# !/usr/bin/env python

Change into

# !/usr/bin/env Python2

Then open the Optimizer tool in the launcher (note!) Cannot be opened in terminal)
