P25.现有网络模型的使用及修改（VGG16）

torchvision.models.vgg16(pretrained: bool = False, progress: bool = True, **kwargs: Any) → torchvision.models.vgg.VGG

Parameters

  • pretrained (bool) – If True, returns a model pre-trained on ImageNet

  • progress (bool) – If True, displays a progress bar of the download to stderr显示下载进度条

class torchvision.datasets.ImageNet(root: str, split: str = 'train', **kwargs: Any)

Parameters

  • root (string) – Root directory of the ImageNet Dataset.

  • split (string, optional) – The dataset split, supports train, or val.

  • transform (callable, optional) – A function/transform that takes in an PIL image and returns a transformed version. E.g, transforms.RandomCrop

  • target_transform (callable, optional) – A function/transform that takes in the target and transforms it.

  • loader – A function to load an image given its path.

import torchvision# train_data = torchvision.datasets.ImageNet("data_image_net", split='train', download=True,
#                                            transform=torchvision.transforms.ToTensor())
from torch import nnvgg16_false = torchvision.models.vgg16(pretrained=False)
vgg16_true = torchvision.models.vgg16(pretrained=True)print(vgg16_true)train_data = torchvision.datasets.CIFAR10('dataset', train=True, transform=torchvision.transforms.ToTensor(),download=True)vgg16_true.classifier.add_module('add_linear', nn.Linear(1000, 10))
print(vgg16_true)print(vgg16_false)
vgg16_false.classifier[6] = nn.Linear(4096, 10)
print(vgg16_false)
