要使用csv模块读取一个 CSV 文件,首先使用open()函数 ➋ 打开它,就像您处理任何其他文本文件一样。但不是在open()返回的File对象上调用read()或readlines()方法,而是将其传递给csv.reader()函数 ➌。这将返回一个reader对象供您使用。注意,您没有将文件名字符串直接传递给csv.reader()函数。
2.Reader 对象的主要方法, 有 4 组参数:General、Contrast、Text Detection 和 Bounding Box Merging, 其返回值为列表形式。reader.readtext( 'chinese.jpg',image,decoder='greedy',beamWidth=5,batch_size=1,workers=0,allowlist="ch_sim",blocklist="ch_tra",detail=1,paragraph=False,min_size=10,...
