Matplotlib envoie un message d'avertissement à cause de findfont - python

Je veux tracer un graphique de base, composé essentiellement de deux listes de la forme x = [1,2,3, ..., d], y = [y1, y2, ..., yd]. après utilisation de _ pyplot.plot(x,y) j'obtiens une énorme quantité de messages d'avertissement faisant référence à erreurs findfont (voir ci-dessous ..)

Je viens d'installer matplotlib. Tous les fils que j'ai pu trouver se réfèrent à la modification manuelle des polices et à l'apparition de messages d'avertissement. Je n'ai rien fait de tel. Je viens d'installer le paquet et c'est tout.

J'utilise pycharm, python 3.6 et windows pour la programmation.

Tout comme une solution alternative, vous pouvez désactiver l'enregistreur du gestionnaire de polices matplotlib.

logging.getLogger('matplotlib.font_manager').disabled = True

J'avais le même problème. J'ai réalisé que j'avais activé le mode DEBUG dans la journalisation, mais je voulais en fait l'activer pour déboguer mon propre script (pas matplotlib). Le correctif consiste à attribuer un nom unique à votre enregistreur et à y activer le mode DEBUG.

Code avant:

log = logging.getLogger()
log.setLevel(logging.DEBUG)

Réparer:

log = logging.getLogger('UNIQUE_NAME_HERE')
log.setLevel(logging.DEBUG)

Et mieux encore, utilisez un nom dynamique qui utilise le nom du module actuel (si votre code est dans un module):

log = logging.getLogger(__name__)
log.setLevel(logging.DEBUG)

La méthode ci-dessus est recommandée et décrite plus en détail ici: https://docs.python.org/3/library/logging.html

Alternativement, vous pouvez plutôt définir le niveau de journalisation sur autre chose que DEBUG (par exemple log.setLevel(logging.CRITICAL)).
