Tensors What is Tensors? Tensors are a specialized data structure that are very similar to arrays and matrices. In PyTorch, we use tensors to encode the inputs and outputs of a model, as well as the model’s parameters. Tensors are similar to NumPy’s ndarr

K-Nearest Neighbor 1. 基础知识 tile 这个函数在numpy中 函数形式：tile (A, reps) 重复A的各个维度，reps是重复的次数 from numpy import tile Array = [1,2,3] y = tile(Array,2) 输出为： [1 2 3 1 2 3] y = tile(Array,(2,2)) 这个相当于先得到 [1 2 3 1 2 3]，再重复 输出为： [[1 2 3 1 2 3] [1 2 3 1 2 3]] y
