Seaborn OS X: seaborn.pairplot() ValueError: 'transform' muss eine Instanz von 'matplotlib.transform.Transform' sein

Question

Die folgenden Schritte wurden innerhalb von jupyter notebook unternommen, um seaborn.pairplot() arbeiten zu lassen. Ein Fehler von /usr/local/lib/python2.7/site-packages/matplotlib/matplotlib/transforms.pyc hat die Funktion abgebrochen.

Im Folgenden sind die Python-Bibliothek Versionen:

print(matplotlib.__version__, sns.__version__) 

('1.5.1', '0.7.1') 

Eine csv der Iris Dataset

data = pandas.read_csv('iris.csv') 
data_no_nans = data.dropna() 
sns.pairplot(data_no_nans) 

Fehlermeldung gelesen wurde:

ValueError: 'transform' must be an instance of 'matplotlib.transform.Transform' 

Regplot funktioniert perfekt

EDIT

Ich vermute, es hat mit matplotlib der Font-Manager eine Fehlfunktion zu tun. Ich löschte fontconfig und würzige Verzeichnisse von ~/.cache/und bekam eine neue Fehlermeldung: Attribute: ‚Modul‘ Objekt hat kein Attribut ‚Gesperrt‘

Answer 1

Also habe ich jetzt meine eigene Frage bin zu beantworten.

löste ich das Problem durch eine Macports virtuelle Umgebung

mit

sudo port selfupdate 
sudo port install python27 
sudo port install py27-virtualenv 


/opt/local/bin/virtualenv-2.7 $HOME/local/python/27 

In .bash_profile:

alias py27="source $HOME/local/python/27/bin/activate" 

Run in Terminal virtuelle env zu setzen und erforderlichen Pakete mit pip zu installieren.

Es ist seltsam, dass die Home-Brew-Installation abgehört hat, und ich frage mich, ob irgendwelche in Konflikt stehenden Pakete installiert waren.

nicht sicher, ob seine verwandten, aber hier ist mein Bash_profile:

# some settings to prefer homebrew paths in case it exists: 
if which -s brew ; then 
    PATH="/usr/local/bin:/usr/local/sbin:$PATH" 
fi 

# set PATH so it includes user's private bin if it exists 
if [ -d "$HOME/bin" ] ; then 
    PATH="$HOME/bin:$PATH" 
fi 

Diese Dinge könnten worden vermasselt.
