不知道起什么名字

public boolean isSymmetric(TreeNode root) { if(null == root){ return true; } return isMirror(root.left, root.right); } private boolean isMirror(TreeNode r1, TreeNode r2){ //判断传入的两个节点是否属于镜像关系 //如果两个节点都为null，结束递归调用 if...

代码实现如下： import torch import torch.nn.functional as F A = torch.ones(3,2) B = torch.ones(2,2) a = torch.Tensor([1,2,3]).reshape(3,1) b = torch.Tensor([4,5]).reshape(2,1) A = torch.mul(A,a) B = torch.mul(B,b) W = torch.rand(6,1) print('W:',W) print(A) pr..
