module '_tkinter' has no attribute '__file__'

配置列表：

python3.5

matplotlib1.5.3

...相关配置

测试程序：

import matplotlib
matplotlib.use('tkagg')

import matplotlib.pyplot as plt
plt.plot([1,2,3,4,5],[4,3,5,6,3])
plt.show()

问题：

进入ipython界面，使用matplotlib时，显示

import matplotlib.pyplot as plt
---------------------------------------------------------------------------

思路：

初步认为这是matplotlib1.5.3的bug

解决步骤：

（1）pip list查看当前matplotlib的版本，是matplotlib1.5.3。（pip install matplotlib安装时默认安装1.5.3）

（2）通过https://pypi.python.org/pypi，查询最新版的matplotlib，现在是2.0.0rc2  

（3）卸载当前的matplotlib，pip uninstall matplotlib

（4）安装指定版本的matplotlib，pip install matplotlib==2.0.0rc2

（5）再次使用matplotlib，问题已解决
