我用py2.7环保署for Windows的免费版本，我有一个使用NetCDF4读取数据的过程我用底图1.0.5从
http://sourceforge.net/projects/matplotlib/files/matplotlib-toolkits/Python的matplotlib /底图错误信息
当我绘制我的数字它的效果好几次，然后我得到以下错误信息，当我重新启动（关闭并再次打开）EPD，直到它再次出现时，问题得到解决。它可能是matplotlib中的错误吗？以及如何解决问题？ 谢谢

它说，它是一个内存错误（即，在内存运行空间），这也解释了为什么会发生不一致，可以通过重新启动IDLE固定。您绘制的数据有多大？ –
它是一个非常大的文件，以1km分辨率覆盖整个大陆的雷达地图。如何在每个情节之后释放记忆？ –
我以为plt.clf（）会清除内存并解决问题，但它没有 –
