Pytorch 中的模型结构及权重文件
1. 模型结构与参数的保存与加载 (To save both the architecture and weights)
将模型结构及参数都保存起来,在后续模型加载时不需要预先定义模型的网络结构,这种方法使用方便,但耗内存。
具体方法如下:
1) 保存
import torch
import torchvision.models as models
# Assuming you have a model instance
model = models.resnet18()
# Save the entire model, including architecture and weights
model_path = 'path/to/your/model.pth'
torch.save(model, model_path)
2)加载:
model = torch.load
