mean(A):返回一个行向量,其第i个元素是A的第i列的算术平均值。 median(A):返回一个行向量,其第i个元素是A的第i列的中值。 mean(A,dim):当dim为1时,该函数等同于mean(A);当dim为2时,返回一个列向量,其第i个元素是A的第i行的算术平均值。 median(A,dim):当dim为1时,该函数等同于median(A);当...
torch.max(X,dim=1)是对行取最大值 dim=1,表面上感觉时对列取最大值,测试一下: X = torch.tensor([[1.0, 1.0], [-1.0, -1.0]]) result,indices = torch.max(X,dim=1) print(result) print(indices) 1. 2. 3. 4. 5. tensor([ 1., -1.]) 如果是对列取最大值,结果应该都是1,因此是...
