我正在尝试在AWS ec2(ubuntu(上运行一些代码。当我注释掉matplotlib中显示图形的部分时，它运行良好。但是，我想查看图表。
当运行代码时，我得到这个错误：
Traceback (most recent call last):

During handling of the above exception, another exception occurred:

我一直在搜索SO和其他来源，并尝试了很多东西，包括：
sudo apt-get install python3-gi
pip install vext
pip install vext.gi
sudo apt install python3-gi
pip3 install --user pgi
此外，这项工作：
$ /usr/bin/python3
Python 3.4.0 (default, Apr 11 2014, 13:05:11)
[GCC 4.8.2] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import gi
>>>
但我的实际代码是在一个有很多依赖项的虚拟环境中，所以这不适用于我实际的代码(/usr/bin/python run.py(。
我遇到了完全相同的问题，但经过大量努力，我设法使TkAgg正常工作(这导致_TkAgg的导入错误(。有点晚了，但有人可能会觉得有用。
FWIW我解决了如下问题(使用TkAgg(：
◉从包管理器安装tk-dev
◉从包管理器重新安装python3 tk
◉从源重建并重新安装matplotlib
◉(当然还有在matplotrc中设置TkAgg(
如果您认为tk-dev和python3-tk安装正确，则需要重建并重新安装matplotlib，以便它在您的后端目录中生成_tkagg.py。
我在LM14上使用Python 3.3(numpy 1.7(。但我认为它应该在Ubuntu/Python3.2上运行
