Hi,
I am following the tutorial from:
https://intel.github.io/robot_devkit_doc
When I run ./demo/rdk_install.sh

[ ERROR ]  Please contact Model Optimizer developers and forward the following information:

with manual installation, same result.

Also tried to install Tensorflow version 1.14.0

Thanks,
