在OSX中导入matplotlib时出现NSException [英] NSException on import of matplotlib, kivy in OSX

问题描述

我正在处理一些在Windows 10上可以正常运行的kivy代码，但是在osx sierra上崩溃，我隔离出了当我沿着matplotlib侧面导入kivy.core.window时发生崩溃的问题:

I'm working on some kivy code that's working fine on windows 10, but crashes on osx sierra, I've isolated that the crash happens when I import kivy.core.window along side matplotlib:

import matplotlib
matplotlib.use("TkAgg")
from matplotlib import pyplot as plt
import kivy.core.window

如果没有matplotlib.use("TkAgg")，它也会崩溃.只是为了说明此问题并未像其他问题所建议的那样解决此问题.

It also crashes without matplotlib.use("TkAgg"). This is just included to show that the issue isn`t fixed by this as other questions suggest.

该异常的输出为:

2017-03-08 13:33:32.461 Python[28614:209475] -[SDLApplication _setup:]: unrecognized selector sent to instance 0x1020ea6c0

)
libc++abi.dylib: terminating with uncaught exception of type NSException

可能是什么原因导致的，我从哪里开始调试这种类型的异常呢?

What could be causing this, and where do I start looking to debug this type of exception it?

解决此问题后，我遇到了一个可能相关的问题，该问题在中指出.

After solving this I ran into a perhaps related problem, noted in this question.

推荐答案

我设法通过运行解决了这个问题

I managed to solved this problem through running

pip install kivy-gardens
garden install matplotlib

我不确定为什么这样做，但确实删除了NSException的这个根.

I'm not sure why this worked, but it did remove this root of the NSException.

我现在由于不同的依赖关系相互作用而得到了另一个NSException，我将以

I'm now getting a different NSException caused by a different interplay of dependencies that I'll post as a new question.
