我已经在我的主目录中成功安装并调用了matplotlib。
[myname@sysimm51 ~]$ python
Python 2.7.6 (default, Nov 11 2013, 13:13:15)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-1)] on linux2
>>> import matplotlib
>>> print matplotlib.__file__
/home/myname/lib/python2.7/site-packages/matplotlib/__init__.pyc
但是当我尝试调用pylab（我的代码需要）时，它给了我以下ImportError。我该如何处理？
>>> import pylab

更新
使用python --pylab我得到了这个：
$ ipython --pylab
