我的任务
分享AttributeError: 'module' object has no attribute 'rcParams'
电脑系统win7 x64
电脑同时安装了python2.7和python3.4
也同时安装了matplotlib for 2.7 和3.4
在pycharm py文件中import matplotlib正常（解释器为python 3.4）
print(matplotlib.__file__ )
D:\python3.4.2\lib\site-packages\matplotlib\__init__.py
但在python console中import matplotlib出现错误：（解释器也为python 3.4）
AttributeError: 'module' object has no attribute 'rcParams'
网上在解决说：(应该是针对linux)
it looks like you have a matplotlib dir in your working directory that is being picked up and you probably don't want it.
You have the matplotlib source directory in your HOME directory and when you run from your home directory, it is being picked up instead of the installation directory. I usually name my src tree "mpl" to avoid this problem
这个好像不行

For Python 2.7 it works. However, I have checked this behavior on two computers with Python 3.4. The Matplotlib module object is broken if it was imported via the "pydev_import_hook" mechanism. I think changes in the import system in Python 3 are the cause of this problem
I can confirm the same problem: in my case a fresh install (from nothing) of Anaconda 2.1.0 of Python 3.4.1. 'import matplotlib' works from an ipython session opened outside pycharm but fails inside.
的确是个bug！

同时装两个更新模块的时候会有冲突吧,建议如果装两个,一个装在windows下面,一个装在linux下面.

可是装的numpy和scipy都import正常没有冲突，只有matplotlib引入出现这种错误，两个版本的我都想要呢
这个怎么解决呢？
