I've followed all the instructions described in: https://docs.openvinotoolkit.org/latest/_docs_install_guides_installing_openvino_raspbian.html
Also installed all dependencies for openvino toolkit as detailed in the install dependencies script and opencv-python package for python3.
I am using a Intel Movidius NCS 2 stick on a raspbian lite distribution, and I was successful in compiling the sample as described in the docs. But when I try to run the face detection sample on a sampel image that I captured on a raspberry pi camera, I get an error, please see the log messages and error below:

What does this error mean and how do I fix/debug it?
I had downloaded the latest openvino toolkit for raspbian. This was the name of the file: l_openvino_toolkit_raspbi_p_2019.1.144.tgz
Should I install the full linux package instead of the raspbian one?
Dear Raghunandan, Chakravarthy,
According to the raspbian install doc you should install the l_openvino_toolkit_raspbi_p_<version>.tgz. But I'm quite surprised that the latest for you is 144. The other mainstream versions are *.148.
Are you sure you're getting the latest and greatest 2019R1.1 ?
Please find a screenshot of what I see in the downloads page: https://imgur.com/CO2eEHx
I selected 2019R1.1 and I can only see 144 version for raspbian. Can you please check and let me know if this the latest version or not? If not can you please send a download link to the latest 148 version?
Our work has been stuck because we are unable to run any models using NCS2 on raspbian and my boss is getting uncomfortable because of the business impact it can have. Please help me resolve this problem asap.
