Hi Simran

This issue seems to be related to Openvino. We've a separate forum for Openvino toolkit. So we're moving this case to Openvino toolkit forum for faster response.

Greetings,

Usually, these kind of error persist when the setupvars is not initiated. Please note that you need to run it each time you open a new terminal/cmd. Better if you could set it up permanently.

Ensure that you are able to run the demo as in this tutorial: https://docs.openvinotoolkit.org/latest/openvino_docs_install_guides_installing_openvino_linux.html

Sincerely,
