Python中cv2模块的imread函数可以正常读取’jpg’,'png’格式的图片,但是不能处理’gif’图片。可以改用imageio模块来处理。 代码语言:javascript 复制 importcv2importimageio defreadImg(im_fn):im=cv2.imread(im_fn)ifim is None:print('{} cv2.imread failed'.format(im_fn))tmp=imageio.mimread(im_fn...

让我们通过添加如下代码来调用read_images函数: path_to_training_images = '../data/at' training_image_size = (200, 200) names, training_images, training_labels = read_images( path_to_training_images, training_image_size) 在前面的代码块中编辑path_to_training_images变量,以确保它与您先前在“...
