Anaconda: Kann nicht importiert werden pylab

Question

Ich kann nicht import pylab mit der neuesten Version von Anaconda (Linux 64 Bit). Andere Pakete scheinen gut zu funktionieren. (Anmerkung: Ich habe nicht sudo Zugang)

Wenn ich versuche,

ich:

Error: No packages found matching: sip 

Ich habe auch Fehler mit:

Irgendwelche Gedanken warum?

Answer 1

hatten nur dieses Problem, und es wurde im Zusammenhang mit welcher qt Backend matplotlib zu verwenden versucht, versuchen:

import PyQt4 

Wenn Sie Sie wahrscheinlich nicht PyQt4 haben haben pyside

import PySide 

Wenn Dies ist der Fall, den Sie brauchen, um die matplotlib.rcParams['backend.qt4'] == 'PySide' nicht 'PyQt4' einzustellen. Sie können dies auch in Ihrer matplotlibrc Datei tun (~/.matplotlib/matplotlibrc)

# find and change line: 
backend.qt4 : PySide 

Hinweis: Wenn Sie Sie es aus dem matplotlib Quellverzeichnis nicht die matplotlibrc Datei kann

import os 
import matplotlib 
mpl_dir = os.path.dirname(matplotlib.__file__) 
os.system("cp {}/mpl-data/matplotlibrc ~/.matplotlib/".format(mpl_dir))
