# TensorDesc简介

TensorDesc用于储存ListTensorDesc.GetDesc()中根据index获取对应的Tensor描述信息。

#### 原型定义

```
template<class T> class TensorDesc {
    TensorDesc();
    ~TensorDesc();
    void SetShapeAddr(uint64_t* shapePtr);
    uint64_t GetDim();
    uint64_t GetIndex();
    uint64_t GetShape(uint32_t offset);
    T* GetDataPtr();
    GlobalTensor<T> GetDataObj();
}
```


#### 模板参数
