In this tutorial, you'll explore Python's __pycache__ folder. You'll learn about when and why the interpreter creates these folders, and you'll customize their default behavior. Finally, you'll take a look under the hood of the cached .pyc files.
state_dict是一个简单的Python字典对象,将每一层映射到它的参数张量。 Introduction state_dict对象是Python字典,所以可以很容易地保存、更新、修改和恢复它们,为PyTorch模型和优化器添加了大量的模块化。注意,只有可学习参数的层(卷积层、线性层等)才在模型的state_dict中有内容。优化器对象(torch.optim)也有一个...
