Constructor and Destructor

Function Usage

Constructs a TensorData.

Method 1: The address of the tensor data and the manager used to manage the tensor data are specified.

Method 2: The address of the tensor data, the manager used to manage the tensor data, the memory occupied by the tensor data, and the location (host or device) of the tensor data are specified.

Method 3: move constructor.

Note: If the manager is nullptr, addr is the address of the tensor data. Otherwise, the address of the tensor data is provided by the manager.
