imageio.imread(uri)

• uri：路径

从指定路径读取一张图片
Reads an image from the specified file. Returns a numpy array
Note that the image data is returned as-is, and may not always have a dtype of uint8 (and thus may differ from what e.g. PIL returns).

返回属性为np.array、uint8、255、HWC

使用很简单

from imageio import imread
img1 = imread('1.jpg')
