Buongiorno,

Sono alle prime armi con Python, volevo provare un semplice programma che ho trovato in rete, per verificare le potenzialità di matplotlib

su Raspberry PI 3 purtroppo quando vado in esecuzione il l'IDE mi da il seguente errore:




Python 3.5.3 (default, Nov 4 2021, 15:29:10)
[GCC 6.3.0 20170516] on linux
Type "copyright", "credits" or "license()" for more information.
>>>
===================== RESTART: /home/pi/Desktop/prova.py =====================
Traceback (most recent call last):
File "/home/pi/Desktop/prova.py", line 11, in <module>
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg, NavigationToolbar2Tk
ImportError: cannot import name 'NavigationToolbar2Tk'
>>>





non riesce ad importare NavigationToolbar2Tk




su windows funziona ma su raspberry no

qualcuno sa darmi una spiegazione??




Grazie





allego sorgente:

Well, you can solve this problem by updating Matplotlib, if still not work then I will recommebnd you to use different IDE or terminals.
Thanks

This error usually happens because your Raspberry Pi is running an older version of matplotlib. In itNavigationToolbar2Tk didn't exist yet — it was called NavigationToolbar2TkAgg.
Try

from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg, NavigationToolbar2TkAgg

Unselfishness
If you want to use the new name (NavigationToolbar2Tk), update matplotlib:

pip3 install --upgrade matplotlib

But on a Pi 3 with Python 3.5, upgrading may be limited, so using NavigationToolbar2TkAgg is usually the simplest fix.
