【Python】读取文件时显示 ‘NoneType‘ object has no attribute ‘shape‘

今天自己用爬虫制作数据集，在用之前能够正常运行的网络去训练爬虫爬下的数据时。显示了一个这样的错误：

Exception in thread Thread-16: Traceback (most recent call last):
File
“/opt/conda/envs/python35-paddle120-env/lib/python3.7/threading.py”,
line 926, in _bootstrap_inner

line 215, in resize_short
h, w = im.shape[:2] AttributeError: ‘NoneType’ object has no attribute ‘shape’

这大概是指读取到的图片维数不对，然后我试着通过：

if(str(type(img))==""):
    print(path)

这两行代码，获取出错图片的路径。发现图片没有背景，导致读取是出错。删除后问题解决。
