下面是下列问题：

我想生成使用Matplotlib和Python的几个图。当我从大多数人的<一听到href="http://stackoverflow.com/questions/7157330/problem-importing-matplotlib-mlab-and-pyplot-in-python-2-7-on-mac-osx-10-6">solutions3..似乎有matplotlib和64位架构之间的兼容性问题。

I am trying to generate a few graphs using Matplotlib and Python. As I hear from a majority of the solutions3.. there seem to be compatibility issues between matplotlib and 64bit architectures.

我从这里

下面是我的错误：

推荐答案

matplotlib未能连接到任何X服务器的GTK显示。

matplotlib is failing to connect to any X server for its GTK display.

有几个选择这里：

1. 运行的本地X服务器和启用X11转发的SSH客户端，以显示你的本地计算机上的输出。您可以通过检查$ DISPLAY环境变量被设置在服务器上验证这是工作。

1. Run a local X server and enable X11 forwarding in your ssh client, to display the output on your local machine. You can verify this is working by checking that the $DISPLAY environment variable is set on the server.

呼叫matplotlib.use（...）来指定不同的显示后端，比如渲染PDF文件，的在的进口pyplot，如：

Call matplotlib.use(...) to specify a different display back-end, for example rendering to pdf file, before importing pyplot, e.g.

进口matplotlib为MPL

mpl.use（AGG的'）

进口matplotlib.pyplot为PLT
