Python Cartopy和matplotlib类型错误：不可损坏类型：'；多重限制'；

我正试图通过遵循Cartopy官方网站上提供的示例来玩弄Cartopy。除了第一个，所有这些都能正常工作

import cartopy.crs as ccrs
import matplotlib.pyplot as plt

ax = plt.axes(projection=ccrs.PlateCarree())
ax.coastlines()

plt.show()

所有行都正常工作，但只要运行plt.show（）命令，就会收到以下错误消息：

Exception in Tkinter callback

有人已经知道这件事了吗？ 我的matplotlib版本是1.4.2，Cartopy版本是0.13.0

非常感谢您的帮助。

这是Cartopy问题跟踪程序上报告的一个问题。基本上，Shapely在1.5.12和1.5.13之间更改了几何体的哈希性。在我们推出新版本的cartopy之前，解决办法是将shapely的安装降级到1.5.12
