"import FigureCanvasGTK" provoques floating exception
Bonjour,
J'ai testé le fichier source fourni dans "http://matplotlib.sourceforge.net/examples/user_interfaces/embedding_in_gtk2.html" (et foruni ci-dessous" afin d'intégrer matplotlib dans une fenêtre gtk.
Mais l'import de FigureCanvasGTK à partir de matplotlib génère une "floating exception".
Comment s'en sortir ?
Merci
