就拿Resnet18举例
在程序中输入
from __future__ import print_function, division
from torchvision import models
model_ft = models.resnet18(pretrained=True)
然后运行，就会出现如下内容
再将这个网址复制到浏览器中，就可以直接下载Resnet18模型。下载结束后，将下载的文件放入你建立的python项目中，再运用如下代码就可以调用Resnet18模型。
model_ft = models.resnet18(pretrained=False)
pre = torch.load('resnet18-5c106cde.pth')
model_ft.load_state_dict(pre)
希望对你有帮助！
其他的学习模型也可以用类似的方法下载，或者可以参看下面的下载网址。
