Pandas 0.19: Erreur d'attribut "propriété inconnue color_cycle" existe toujours lors de l'exécution de la boîte à moustache

Question

Contrairement à ce qui a été dit here, le AttributeError: Unknown property color_cycle est toujours persistant dans la version la plus récente de Pandas (0.19.0-1).

Dans mon cas, j'ai un dataframe semblable à cela, bien que beaucoup plus (3.000.000 lignes):

 A   B C 
1 05010001 17 1 
2 05020001 5 1 
3 05020002 11 1 
4 05020003 2 1 
5 05030001 86 1 
6 07030001 84 2 
7 07030002 10 2 
8 08010001 16 3 

Pour une raison quelconque, si je mets en œuvre ce très exemple, il n'y a aucune erreur. Dans mon cas réel, l'exécution simple

df.boxplot(by='C')

déclenche ce gâchis:

Et je suis parti avec un terrain de 4 volet blanc, quand il aurait dû y avoir un seul avec 5 boxplot colonnes:

Comment résoudre ce problème?

Answer 1

Je me suis vérifié que l'on a besoin d'avoir pandas 0.19.0-1ensemble avec matplotlib 1.5.1-8 pour ne pas rencontrer cette erreur.
