ModuleNotFoundError: No module named 'sgmllib'

Question

pytorch的官方教程，执行到下面的代码就报错。

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：

经过查阅资料发现python3.6.1已经没有这个库了，坑人啊。。。。。

sgmllib是2.6以后引入python，在3.0以后这个库被移除了。如果你的python版本<2.6或者>=3.0就找不到这个module。
如果你要使用已有的、依赖sgmllib的代码，安装python2.7等合适的版本。如果要迁移到3.0环境，需要移植代码，可以使用html.parser.HTMLParser
