我试图运行一些Python 3代码，它首先显示一个OpenCV窗口，当它关闭时，它应该使用MatplotLib绘制一些东西。然而，在plt.show()调用程序崩溃：python3.6意外退出。
import numpy as np
import matplotlib
matplotlib.use("TkAgg") # <== Doesn't solve the problem
import matplotlib.pyplot as plt
import cv2
#cv2.ocl.setUseOpenCL(False) <== Doesn't solve the problem
im = np.zeros((100,100,3))
cv2.imshow('test', im)
cv2.waitKey(0)
plt.plot(np.sin(np.linspace(0,20,200)))
plt.show() # <== Crashes on this call
在其他StackOverflow帖子中，我发现将MatplotLib后端设置为TkAgg应修复此问题或设置setUseOpenCL(false)。但是，这些潜在的修复程序都无法在我的MacBook上运行。我尝试了几件事，比如更改导入顺序，尝试交换MatplotLib后端。任何人都知道如何解决这个问题？
MacOS Sierra 10.12.3 Python 3.6.0 TKinter版本8.5 OpenCV版本3.2.0 MatplotLib版本2.0.0

不确定它是否会帮助你们/女孩，但我遇到了类似的问题，试图将matplotlib嵌入到一个kivy应用程序（也在Mac上），经过几个小时的谷歌搜索，重写类，卸载和重新安装，并在一点上甚至试图完全使用不同的图书馆。我发现最简单的解决方案是完全关闭（'TkAgg'）后端，因为它看起来不太好看然后明确声明OSX一个
import matplotlib
matplotlib.use("MacOSX")
import matplotlib.pyplot as plt
为我工作，奥卡姆斯剃刀和我想的一切，祝你好运！
不知道matplotlib，但我可以想象窗口管理可能存在问题。试试这个：
cv2.imshow('test', im)
cv2.waitKey(1)
cv2.destroyWindow('test')
至少这是处理已经打开的cv2.imshow（）窗口的正确方法，当它们不再使用时。
