Webbfrom math import ceil: import torch: from torch import nn: import torch.nn.functional as F: def exists(val): return val is not None # nucleus: def top_p(logits, thres = 0.9): 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这段代码的作用是创建一个空列表global_context,然后对于keep_features中的每个元素f,如果它的索引i是0或1,就对它进行5x5的平均池化操作(nn.AvgPool2d(kernel_size=5, stride=5)),并将结果添加到global_context中。 Webb11 maj 2024 · f = nn.Softmax (dim = 1) 结果:tensor ( [ [0.0055, 0.9945], [0.9677, 0.0323]], dtype=torch.float64) 可以发现是每一行和为1 所以,当nn.Softmax的输入是一个二维张量时,其参数dim = 0,是让列之和为1;dim = 1,是让行之和为1。 若nn.Softmax的输入是三维张量时,dim的取值就变成了0,1,2,那又是代表什么意思呢,看下面的例子。 a = … Webblogit原本是一个函数,它是sigmoid函数(也叫标准logistic函数) p (x) = \frac {1} {1+e^ {-x}} 的反函数: logit (p) = \log\left (\frac {p} {1-p}\right) 。 logit这个名字的来源即为 log … bleach 215 gogoanime
