Hi -- I just wanted to try Processing with Python so I used the Flatpak version. However it does not look like the flatpak and work with Python.

See the messages from the console. it keeps saying that it "assumes a registry is created on port 8220". Nothing actually happens so I do not believe this resgistry has been created.

 $ flatpak run org.processing.processingide
 $ You are running Processing revision 0265, the latest build is 0269.
 $ 
 $ created registry at port 8220
could not create registry; assume it's already created
Reference Tool 1.1.1 by Jae Hyun
could not create registry; assume it's already created

Is there something I need to do to activate with Python to and the Flatpak installer?

This is 64-bit ubuntu 19.04
All packages are up to date.
