  1. input 和 label 的维度设置 [batch_size,dim] 是基于什么考虑呢?
  2. input 和 label 接受的 data_type 是什么样子的呢?

- input:Tensor, 维度为[N,*],其中N是batch_size, `*` 是任意其他维度。数据类型是float32、float64。
- label:Tensor, 维度为[batchsize,num_classes]维度、数据类型与输入 input 相同。

这里的 API 参数设计还存在一些问题:

  1. label 的维度应该与input的维度相同
  2. label 的数值只能为 1 或者 -1
  3. label 需要支持 [int32, int64, float32, float64] 数据类型
