◆ 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 *
