Detailed Description

Pass to insert permutation operations for input and output for layout and/or data type conversions.

If actual layout or data type of input/output by user request is different with model's layout or data type, this pass will insert permutation operations for input/output nodes.

If actual layout and data type of input/output by user request is same with model's layout and data type, this pass does nothing.
