我用py2.7環保署for Windows的免費版本，我有一個使用NetCDF4讀取數據的過程我用底圖1.0.5從
http://sourceforge.net/projects/matplotlib/files/matplotlib-toolkits/Python的matplotlib /底圖錯誤信息
當我繪製我的數字它的效果好幾次，然後我得到以下錯誤信息，當我重新啓動（關閉並再次打開）EPD，直到它再次出現時，問題得到解決。它可能是matplotlib中的錯誤嗎？以及如何解決問題？ 謝謝

它說，它是一個內存錯誤（即，在內存運行空間），這也解釋了爲什麼會發生不一致，可以通過重新啓動IDLE固定。您繪製的數據有多大？ –
它是一個非常大的文件，以1km分辨率覆蓋整個大陸的雷達地圖。如何在每個情節之後釋放記憶？ –
我以爲plt.clf（）會清除內存並解決問題，但它沒有 –
