执行飞桨2.0高层api例子里的语句：https://github.com/PaddlePaddle/FluidDoc/blob/release/2.0-alpha/doc/fluid/beginners_guide/hapi.md

from paddle.incubate.hapi.vision.transforms import transforms import cv2

img_path = "./work/testpd.jpg" img = cv2.imread(img_path)

使用Compose 将可以将多个数据增强函数组合在一起

trans_funcs = transforms.Compose([transforms.RandomResizedCrop(224), transforms.RandomHorizontalFlip(), transforms.BrightnessTransform(0.2)]) label = None img_processed, label = trans_funcs(img,label)

执行报错： fail to perform transform [<paddle.incubate.hapi.vision.transforms.transforms.RandomResizedCrop object at 0x7fee5f5b8bd0>] with error: call() takes 2 positional arguments but 3 were given and stack: Traceback (most recent call last): File "/opt/conda/envs/python35-paddle120-env/lib/python3.7/site-packages/paddle/incubate/hapi/vision/transforms/transforms.py", line 94, in call data = f(*data) TypeError: call() takes 2 positional arguments but 3 were given
