  // User tensors are not registered in _tensor_info_map but objects for them are exist
  // in the tensor registry.

◆ nativeOwnTensorAt()

basic::Tensor * onert::backend::builtin::TensorBuilder::nativeOwnTensorAt ( const ir::OperandIndex & ind )

Get tensor with a specific OperandIndex.

Parameters

ind	OperandIndex for the tensor. There must exist a tensor with this ind. If not, program will crash with assert or exception.

Returns: operand::Tensor *
