AttributeError: ‘NoneType‘ object has no attribute ‘shape‘
2022-07-24 05:15:00 【小新很新】
在运行训练文件时，出现了这样的问题：“AttributeError: ‘NoneType’ object has no attribute ‘shape’”。
原因： 1.图片不存在（路径不存在， 路径包含中文无法识别） 2.读取的图片内容和默认读取时参数匹配不匹配。（默认读取的是3通道的彩色图）例如读取到的图片是灰度图，就会返回None。3.当给出的路径不存在时， cv2.imread() 返回 None ，因此稍后将此 None 值视为 NumPy 数组时会发生错误。
有时可用 try except 语句跳过
