Data Structures

struct  DLContext
 A Device context for Tensor and operator. More...
 
struct  DLDataType
 The data type the tensor can hold. More...
 
struct  DLTensor
 Plain C Tensor object, does not manage memory. More...
 
struct  DLManagedTensor
 C Tensor object, manage memory of DLTensor. This data structure is intended to facilitate the borrowing of DLTensor by another framework. It is not meant to transfer the tensor. When the borrowing framework doesn't need the tensor, it should call the deleter to notify the host that the resource is no longer needed. More...
