◆ CreateTensorHandle() [2/4]

std::unique_ptr< ITensorHandle > CreateTensorHandle ( const TensorInfo & tensorInfo,

Utility Functions for backends which require TensorHandles to have unmanaged memory.

These should be overloaded if required to facilitate direct import of input tensors and direct export of output tensors.
