通过ssh崩溃的交互式matplotlib，Anaconda Scientific Python分发

Question

我在一台远程Mac OS 10.8.5机器上安装了Anaconda，我正试图将matplotlib图形转发回我的本地机器，但IPython一直试图使用远程机器的本地图形并崩溃。其他人经历过这种情况吗？我可以用旧的Enthought Python Distribution（EPD）来做到这一点，所以我知道相关的机器都是为它设置的

我在其他地方问过这个问题，但运气不好。谢谢你的帮助。

从Anaconda 2.0开始，Continuum停止将tk与X11链接，而是链接到Cocoa，这使得试图转发网络图形会使解释器崩溃。当我将tk降级到链接到X11:的最后一个版本时，使用TkAgg后端的交互式matplotlib的网络转发再次工作

conda install tk=8.5.13

缺点是现在我无法再升级/安装任何试图更新tk的东西。此外，Qt4Agg交互式后端仍然会使解释器崩溃。我想这是向前迈出的一步。

编辑：我看到你可以将包固定在某个版本，如这里所述。
