importer matplotlib.pyplot se bloque

J'essaie de lancer matplotlib sur OS X 10.8.4. J'ai installé matplotlib et les dépendances (libping, freetype, numpy, scipy). Je suis capable d'importer matplotlib très bien. Cependant, si j'essaie d'importer matplotlib.pyplot, il se bloque. Il n'y a pas d'erreur, c'est juste que rien ne se passe.

>>> import matplotlib.pyplot

... J'ai attendu peut-être 20 minutes et rien ne se passe. J'utilise la version 1.2.1, mais j'ai même désinstallé cette version et essayé la version 1.2.0, mais en vain. J'ai vu un certain nombre de questions sur SO à propos des erreurs d'importation avec matplotlib.pyplot, mais rien ne s'y accroche. J'ai ensuite essayé de le faire fonctionner avec la distribution python Enthought/Canopy, mais là encore, le même problème persiste. Voici ce que je vois si je tue l'importation:

La sortie était la même lorsque j'utilisais le python 2.7 par défaut fourni avec OS X.

Permettre à import matplotlib.pyplot de s'exécuter pendant quelques heures puis d'interrompre l'importation me donne maintenant le résultat suivant:

KeyboardInterrupt

Est-ce que quelqu'un sait ce que le for x in walk(new_path, topdown, onerror, followlinks): récursif pourrait indiquer?

Vous pouvez résoudre le problème sur Mac OS X Mavericks et Yosemite en procédant comme suit:

cd ~/.matplotlib/
fc-list  # Should take a couple minutes.

Une fois que fc-list est terminé, vous pourrez importer le package à l'aide de import matplotlib.pyplot as plt. C'est le problème de github avec la solution. Il semble que le bogue soit lié au cache de polices.

J'ai compris ce qui se passait. Espérons que la solution est utile aux autres. Dans le dossier /usr/X11/lib, il y avait un lien symbolique pour le répertoire qui renvoyait à lui-même. Cela semble avoir créé une boucle infinie. Lorsque j'ai supprimé le lien, l'importation a fonctionné.

J'avais le même problème sous Linux.

Il s'est avéré que matplotlib rencontrait quelques problèmes pour comprendre le back-end d'interface graphique à utiliser.

Le fait de dire explicitement d'utiliser l'arrière-plan Tkinter - ce qu'il fait par défaut, à l'aide de la commande suivante, a résolu le problème:

%matplotlib tk

Cette suivie par l'importation

import matplotlib.pyplot as plt

travaillé comme prévu.
