首先安装依赖：pip install -i https://mirrors.aliyun.com/pypi/simple/ torchvision

方法一

from PIL import Image
from torchvision import transforms

if __name__ == '__main__':
    image = Image.open('57D194A1-3CB3-405B-9034-62A57B738464_1_105_c.jpeg')
	# 重设图片尺寸
    target_img = transforms.Resize(size=(200, 150))(image)
    # 显示图片并保存
    target_img.show()
    target_img.save('test.png')  # 保存

方法二

from PIL import Image
from torchvision import transforms


def resize_image(image): # 写成函数的格式
    Resize = transforms.Resize(size=(200, 150))
    resized_image = Resize(image)
    return resized_image


if __name__ == '__main__':
    image = Image.open('57D194A1-3CB3-405B-9034-62A57B738464_1_105_c.jpeg')
    target_img = resize_image(image)
    # 显示图片并保存
    target_img.show()
    target_img.save('test.png')  # 保存
