解压预训练权重文件时报错

[Alive1024]

使用 models 中的模型时，例如 model = vgg11(pretrained=True) ，成功下载 zip 权重文件后，解压过程出错，导致解压中断、参数文件不完整。如果自行将下载的 zip 解压，就能正常使用。多个模型都有同样的问题。

代码看看，我这里没报错

from flowvision.models import vgg11

model = vgg11(pretrained=True)

可以把你目前遇到有问题的模型列一个list嘛，我们这边会一一查看并修复~

应该不是权重的问题，他用的是docker，待会儿他把东西都放上来

一开始是有问题，用着用着又突然没问题了。
