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): File "D:/exercise/AI/testAI/linear regression/ex1_1.py", line 3, in <module> import matplotlib.pyplot as plt File "D:\Program Files\Python 3.5\lib\site-packages\matplotlib\pyplot.py", line 115, in <module> _backend_mod, new_figure_manager, draw_if_interactive, _show = pylab_setup() File "D:\Program Files\Python 3.5\lib\site-packages\matplotlib\backends\__init__.py", line 62, in pylab_setup [backend_name], 0) File "D:\Program Files\Python 3.5\lib\site-packages\matplotlib\backends\backend_tkagg.py", line 4, in <module> from . import tkagg # Paint image to Tk photo blitter extension.

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~
