Webb13 mars 2024 · 这段代码打印一条消息,告诉你程序正在构建一个 "多层神经网络Sequential(顺序)模型"。 "Sequential" 模型是一种常用的深度学习模型,它由多个网络层按顺序堆叠而成,每一层可以是一个神经元层或一个卷积层或者是一个池化层等等。
Webb27 okt. 2024 · Then, we ask our model to generate a logits vector for the next word/token. After applying softmax and sorting these probabilities in descending order, we have a vector, idxs, which lists the indices of each token in our vocab in order by their respective probabilities. At this stage, we could just pick the token which has the highest probability. Webb25 sep. 2024 · To get the probabilities, you should probably use probs = F.softmax (outputs, dim=1), since you are using nn.CrossEntropyLoss as the criterion which means …
1 Answer Sorted by: 1 Apart from dim=0, there is another issue in your code. Softmax doesn't work on a long tensor, so it should be converted to a float or double tensor first >>> input = torch.tensor ( [1, 2, 3]) >>> input tensor ( [1, 2, 3]) >>> F.softmax (input.float (), dim=0) tensor ( [0.0900, 0.2447, 0.6652]) Share Improve this answer Follow Webb上次写了一个GCN的原理+源码+dgl实现brokenstring:GCN原理+源码+调用dgl库实现,这次按照上次的套路写写GAT的。 GAT是图注意力神经网络的简写,其基本想法是给结点的邻居结点一个注意力权重,把邻居结点的信息聚合到结点上。 使用DGL库快速实现GAT. 这里以cora数据集为例,使用dgl库快速实现GAT模型进行 ...
