torch中文教程报错：ModuleNotFoundError: No module named 'sgmllib'

pytorch的官方中文教程，执行到下面的代码就报错：
我进行安装transformer：

!pip install transforms

代码部分：

import transforms as T
def get_transform(train):
    transforms = []
    transforms.append(T.ToTensor())
    if train:
        transforms.append(T.RandomHorizontalFlip(0.5))
    return T.Compose(transforms)

报错代码：

pytorch的torchvision自带有transforms不用，为什么要用别的呢？安装对应的torchvision就行了
