Unsure how to proceed with executing the benchmark_app.py or if installing openvino from pip was proper.  Any assistance or guidance would be helpful - attempting to run several benchmarks.  Thank you.

Hi Rcotton,

Thank you for reaching out to us.

The error you encountered ModuleNotFoundError: No module named 'openvino' probably due to you did not set up the environment variables in a new terminal.

Please run setupvars.bat every time you open a new terminal.

Before you run the benchmark_app.py, please change the directory to:

<INSTALL_DIR>\deployment_tools\tools\benchmark_tool and install the requirements by executing the command:

pip install -r requirements.txt

On the other hand, I noticed you run benchmark_app.py with mobilenet-v2.caffemodel. Please use the XML file that you have generated which is located at:

C:\Users\User\Desktop\Models\public\mobilenet-v2\ir\mobilenet-v2.xml

Please try the following command after you have set up the environment variables:

python benchmark_app.py -m <PATH_TO_XML file>\mobilenet-v2.xml

Regards,

Wan
