[SOLVED]ImportError: No module named pydot | rqt_graph

edit

I'm running ROS Kinetic on Fedora 29.

I run these commands in the following way:

rosrun turtlesim turtlesim_node
rosrun turtlesim turtle_teleop_key

After these two commands I run rqt_graph and it gives the following error:

Warning: QT_DEVICE_PIXEL_RATIO is deprecated. Instead use:
   QT_AUTO_SCREEN_SCALE_FACTOR to enable platform plugin controlled per-screen factors.
   QT_SCREEN_SCALE_FACTORS to set per-screen factors.
   QT_SCALE_FACTOR to set the application global scale factor.

The initial warning doesn't seem to create much trouble. I've made sure to install both python3-pydot and graphviz but nothing changed.
