After obtaining a trained .pb model, you can use the ATC tool to convert the .pb model into an .om offline model, which then can be used for offline inference on Ascend AI Processor.
For details about how to convert the .pb model into an .om offline model, see ATC Instructions.
For details about how to load the .om offline model for inference application development, see CANN AscendCL Application Software Development Guide (C&C++).
