matplotlib无法导入pylab

Question

我已经在我的PC上安装了matplotlib以及它的要求Numpy和scipy ，但是在导入pylab时出现了以下错误消息：

   >>> from matplotlib import pylab
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/anaconda/lib/python2.7/site-packages/matplotlib-1.4.x-py2.7-linux-x86_64.egg/matplotlib/pylab.py", line 230, in <module>

    from matplotlib._path import (affine_transform, count_bboxes_overlapping_bbox,
ImportError: /anaconda/lib/python2.7/site-packages/matplotlib-1.4.x-py2.7-linux-x86_64.egg/matplotlib/_path.so: undefined symbol: PyUnicodeUCS2_AsEncodedString

据我记得它曾经工作，但现在我收到错误消息。 我什至重新安装了它，但没有帮助。 我该如何解决？

Answer 1

可能是您失踪了：

import matplotlib as mpl

但是，如果这样不起作用。 重新安装Anacoda发行版，然后确保已安装numpy和scipy。

然后，程序的顶部是：

import numpy as np
import scipy
import matplotlib as mpl
import pylab
