Error when "import matplotlib.pyplot as plt"
提问by user2928318
I am very new to python. So, my problem might be too simple to be solved. But I cannot. Please help me! I did not have any problem to use "plt", but it suddenly shows error message and does not work, when I import it. Please see the below.
我对python很陌生。所以，我的问题可能太简单而无法解决。但是我不能。请帮我！我使用“plt”没有任何问题，但是当我导入它时它突然显示错误消息并且不起作用。请参阅以下内容。
>>> import matplotlib

Try to type sudo apt-get install python-matplotlibin a terminal. In your message you typed it in ipython console. This is a bash command, not a python one.
尝试输入sudo apt-get install python-matplotlib终端。在您的消息中，您在 ipython 控制台中输入了它。这是一个 bash 命令，而不是 python 命令。
You need to quit ipython before. For that use Ctrl + D
您需要先退出 ipython。为了那个用途Ctrl + D

I have this problem before.
我以前有这个问题。
What the conditions of mine is that I have install multiply versions of python and numpyin my OS. That's why the python can't find the right numpy to support the matplotlib.
我的条件是我在我的操作系统中安装了多个版本的 python 和 numpy。这就是为什么python找不到正确的numpy来支持matplotlib的原因。
The method I choose to solved this problem is the modify the $PYTHONPATHby editing the file .bashrcin my home path.
我选择解决这个问题的方法是通过在我的主路径中编辑文件.bashrc来修改$PYTHONPATH。
Change the order of the python install path shown, like putting the path "/usr/lib/python2.7/dist-packages"in the front of the $PYTHONPATH.
更改显示的 python 安装路径的顺序，例如将路径“/usr/lib/python2.7/dist-packages”放在$PYTHONPATH的前面。
Maybe you can find something amazing. Good luck for you!!
也许你会发现一些惊人的东西。祝你好运！！

something wrong with tkinter I guess, try adding:
我猜 tkinter 有问题，请尝试添加：
import matplotlib as mpl
mpl.use('TkAgg')
in the front of import matplotlib.pyplot as plt.
在前面import matplotlib.pyplot as plt。
