pytorch 自带resnet模型加载与使用

加载resnet18模型与使用

import torch
import torch.nn as nn
from torchvision import models

class resnet18(nn.Module):
    def __init__(self):
        super(resnet18, self).__init__()
        self.model = models.resnet18(pretrained=True)
        self.num_features = self.model.fc.in_features
        self.model.fc = nn.Linear(self.num_features,10)
    def forward(self,x):
        out = self.model(x)
        return out
def pytorch_resnet18():
    return resnet18()
