Hi, first of all, thanks for OpenVino.

I'm having trouble running the demo sample with the following error.

Hi Sonny,

Which demo sample are you running? What command are you using to execute it?

Kind Regards,

Hi Sonny,

This is a known issue with the OpenVINO toolkit 2019 R3 release. The latest release contains the fix, please download OpenVINO toolkit 2019 R3.1. Basically, there is a compatibility issue with the latest netoworkx python library.

You can also fix the issue by manually installing networkx version 2.3 with pip3 install networkx==2.3 but I recommend installing the latest OpenVINO version.

Regards,

Jesus
