CreateTensorHandle() [2/4]

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

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.
