Obsolete feature in Python 3.3

[JacquesLB]

While using Pyro2 (for teaching purposes), I keep getting this message:

"The 'add_all' parameter of init() was deprecated in Matplotlib 3.3 and will be removed two minor releases later. If any parameter follows 'add_all', they should be passed as keyword, not positionally."

No harm up to now, but it might become an issue soon. Would it be possible to upgrade the code?

Thank you for your work. Cheers.

Thanks for the report. I am not sure that parameter is even needed. I will look into this shortly.
