ImportError: No module named 'tkinter' Windows解决办法

Python写线性回归算法，导入了几个科学计算库，运行时报这样的错：

"D:\Program Files\Python 3.5\python.exe" "D:/exercise/AI/testAI/linear regression/ex1_1.py"
Traceback (most recent call last):

ImportError: No module named 'tkinter'

网上折腾了半天，想找到tkinter库，都没找到合适的答案。

然后想是不是Python版本太低了，又下了其他高版本，安装时发现了这一个选项

重新安装一下，然后OK了~
