Installed Intel® Distribution of OpenVINO™ Toolkit -  w_openvino_toolkit_p_2021.3.394,  python 3.7.4, Visual Studio Community 2019 installing the C++ and CMake libraries.

 

Set Environmental Variables:

cd "C:\Program Files (x86)\Intel\openvino_2021\bin\"
.\setupvars.bat

 

Install Pre-Requisites:

cd "C:\Program Files (x86)\Intel\openvino_2021\deployment_tools\model_optimizer\install_prerequisites"
.\install_prerequisites.bat

 

Download Benchmark Model:

ModuleNotFoundError: No module named 'openvino'

 

Attempted to install openvino from pip:

Output - Reran benchmark_app.py with new import error: 

Traceback (most recent call last):

ModuleNotFoundError: No module named 'openvino.tools'

 

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
