初识Pytorch使用transforms的代码

import os
from torchvision import transforms
from PIL import Image

root_path = "D:\\data\\basic\\Image"
label_path = "aligned"

# 1.获取aligned第一张图的名字
img_dir = os.path.join(root_path, label_path)
img_list = os.listdir(img_dir)
img_path = img_list[0]

# 2.获取aligned第一张图的路径
img = os.path.join(root_path, label_path, img_path)

# 3.使用python自带的PIL获取图片
img = Image.open(img)

# 4.将PIL利用transforms转换成ToTensor
to_tensor = transforms.ToTensor()  # 创建totensor ()
img = to_tensor(img)  # 使用to_tensor直接将图片的PIL转化为tensor

print(img)
# transforms
