对于成功使用 PyTorch 这样的工具,对张量执行操作并有效地对其进行索引的能力至关重要。现在您已经了解了张量的基础知识,随着您在本书中的学习过程中,您对张量的灵活性将会增长。 现在我们可以回答一个问题:我们如何将一段数据、一个视频或一行文本表示为张量,以便适合训练深度学习模型?这就是我们将在本章学习的内容。
value = torch.rand(1).item() 张量形变 # 在将卷积层输入全连接层的情况下通常需要对张量做形变处理,# 相比torch.view,torch.reshape可以自动处理输入张量不连续的情况。tensor = torch.rand(2,3,4)shape = (6, 4)tensor = torch.reshape(tensor, shape) ...
self.eps = eps #Extra learning parameters gamma and beta are introduced to scale and shift the embedding value as the network needed. self.gamma = nn.Parameter(torch.ones(1)) self.beta = nn.Parameter(torch.zeros(1)) def forward(self, input): mean = input.mean(dim=-1, keepdim=True)...
Also in this release as an important security improvement measure we have changed the default value forweights_onlyparameter oftorch.load. This is a backward compatibility-breaking change, please seethis forum postfor more details. This release is composed of 3892 commits from 520 contributors since...
