Hi Wei-Han C.,

the error comes from an incorrect use of the cpu_extension parameter. --cpu_extension is the path to the extension library (cpu_extension.dll) that you can find in the bin folder of the inference engine: deployment_tools\inference_engine\bin\intel64\Release (or Debug)

Best, 

Severine
