import numpy as np
from PIL import Image
from paddle.vision.transforms import functional as F


for (root , dirs, files ) in os.walk("dataset", topdown=False):
    for name in files:
        abs_name=os.path.join(root, name)
        print(absname)
        img = Image.open(abs_name)
        rotated_img = F.rotate(img, 90)
        print(rotated_img.size)
        fake_name=os.path.join(root,"fake_"+ name)
        print(fake_name)
        rotated_img.save(fake_name)
