Cartopy和matplotlib类型错误：unhashable类型：“MULTILINESTRING”

我想通过以下官方Cartopy网站提供的例子来打了一下周围有Cartopy。他们都正常工作，但第一Cartopy和matplotlib类型错误：unhashable类型：“MULTILINESTRING”

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

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

plt.show()

所有线路正常运行，但只要我运行plt.show（）命令，我得到了以下错误消息：

Exception in Tkinter callback

    File "/usr/lib/python2.7/lib-tk/Tkinter.py", line 1539, in __call__

    return self.data.setdefault(ref(key, self._remove),default)

是否有人已经对此有所了解？我的matplotlib版本是1.4.2，Cartopy版本是0.13.0

非常感谢您的帮助。

这是在https://github.com/SciTools/cartopy/issues/682汇报了Cartopy问题跟踪器的问题。基本上，匀称改变的几何形状的hashability 1.5.12和1.5.13之间。解决办法，直到我们有cartopy的一个新版本，是你的身材匀称的安装降级到1.5.12。
