借助Kaggle快速下载PyTorch预训练模型

pytorch里的预训练模型，使用默认的方式下载会非常慢。最近尝试了借助Kaggle下载。
这里有所有模型的列表 https://github.com/pytorch/vision/tree/master/torchvision/models

model_urls = {
    'resnet18': 'https://download.pytorch.org/models/resnet18-5c106cde.pth',
    'resnet34': 'https://download.pytorch.org/models/resnet34-333f7ec4.pth',
    'resnet50': 'https://download.pytorch.org/models/resnet50-19c8e357.pth',
    'resnet101': 'https://download.pytorch.org/models/resnet101-5d3b4d8f.pth',
    'resnet152': 'https://download.pytorch.org/models/resnet152-b121ed2d.pth'
    'inception_v3_google': 'https://download.pytorch.org/models/inception_v3_google-1a9a5a14.pth',
    'densenet121': 'https://download.pytorch.org/models/densenet121-a639ec97.pth',
    'densenet169': 'https://download.pytorch.org/models/densenet169-b2777c0a.pth',

    'densenet161': 'https://download.pytorch.org/models/densenet161-8d451a50.pth',
    'alexnet': 'https://download.pytorch.org/models/alexnet-owt-4df8aa71.pth',

    'vgg16': 'https://download.pytorch.org/models/vgg16-397923af.pth',
    'vgg19': 'https://download.pytorch.org/models/vgg19-dcbb9e9d.pth',
    'vgg11_bn': 'https://download.pytorch.org/models/vgg11_bn-6002323d.pth',
    'vgg13_bn': 'https://download.pytorch.org/models/vgg13_bn-abd245e5.pth',
    'vgg16_bn': 'https://download.pytorch.org/models/vgg16_bn-6c64b313.pth',
    'vgg19_bn': 'https://download.pytorch.org/models/vgg19_bn-c79401a0.pth',
}

我在Kaggle上用一个notebook下载了这些模型，在output里可以找到这些模型的下载链接。
https://www.kaggle.com/xiedaicheng/download-pytorch-model?scriptVersionId=29833614

下载后放进

 .cache/torch/checkpoints

或者

 /home/user/.torch/models

就可以使用这些模型了。
