Follow up on issue #350: Can not run ncappzoo in Raspberry Pi


Hello, I wanted to use make run to run model in Raspberry Pi I followed instructions given on issue #350 and corrected the PYTHONPATH, Now it can find file, buy it seems it is unable to find 20180408-102900.bin, '20180408-102900.xml, which is understandable as RaspberryPI does not have model optimizer in it.  AS you can see the directory has 20180408-102900..pb,  I then took the 20180408-102900.pb file and wanted to convert using my LInux machine but found error  - which  opened up another ticket. 

Can you please suggest what I am doing wrong.

Thank you for reaching out.

We recommend you look at this section and follow the steps to add the Model Optimizer to Raspberry Pi. Also, we recommend you to check the Model Downloader that is already included in OpenVINO.

As another step, please run the following script to temporarily set the environment variables:

source /opt/intel/openvino/bin/
