ipython notebook - $DISPLAY 变量错误 [英] ipython notebook - $DISPLAY variable error

问题描述

我在 ubuntu 虚拟机上运行 IPython notebook.到目前为止一切都很好，除了我无法进行交互式 matplotlib 绘图.

I am running IPython notebook on an ubuntu vm. Everything works great so far, except I'm unable to do interactive matplotlib plots.

我得到的错误是:TclError: no display name and no $DISPLAY environment variable

我只是想学习这些超级基础的教程.

And I'm just trying to follow these super basic tutorials.

有什么建议吗?我做了一些研究，但似乎没有什么适用于从 ubuntu 机器运行 iPython.我知道我忽略了一些明显的东西.

Any tips? I've done some research but nothing seems applicable to running iPython from an ubuntu machine. I know I'm overlooking something obvious.

在与 ThomasK 谈过这件事后，似乎我需要在 iPython 中按照 %matplotlib inline 运行 %matplotlib nbaggs 以从我的 VM 中获得交互性.

After speaking with ThomasK about this, it seems I need to run %matplotlib nbaggs following %matplotlib inline from within iPython to get the interactivity from within my VM.

但是，交互性仅在最新版本的 matplotlib (1.4.x) 中可用，因此我需要从 1.3.x 升级.

However, interactivity only came available in the latest release of matplotlib (1.4.x) and so I needed to upgrade from 1.3.x.

运行 sudo pip install matplotlib --upgrade 后，我的 .pip_log 中出现以下错误.

After running sudo pip install matplotlib --upgrade I got the following error in my .pip_log.

有什么建议吗?

推荐答案

在此之前运行

%matplotlib inline
