The most important class in the Python Imaging Library is the Image class, defined in the module with the same name. You can create instances of this class in several ways; either by loading images from files, processing other images, or creating images from scratch. 解释:Python映像库中最重...

二、Image PIL Lib "数据集划分" 的要点 常见数据集格式:.mat. npz, .data train_test_split 文件读写 一、文件打开 传统方法的弊端 Ref:python 常用文件读写及with的用法 如果我们open一个文件之后,如果读写发生了异常,是不会调用close()的,那么这会造成文件描述符的资源浪费,久而久之,会造成系统的崩溃。
