Dear Domoney, William
I'm not aware of any converter.py within OpenVino (your command above shows mo.py) but did you install your Model Optimizer Pre-requisites ? I believe that may be your problem.
If you google the error:
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xa1 in position 12206: invalid start byte
It's a common error discussed on Stack Overflow but the error itself has nothing to do with OpenVino or Model Optimizer. It has to do with Python tools which Model Optimizer depends upon.
Thanks,
Shubha

Thanks Shubba
Model converter usage
The basic usage is to run the script like this:
./converter.py --all
This will convert all models into the Inference Engine IR format. Models that were originally in that format are ignored. Models in PyTorch's format will be converted in ONNX format first.
https://docs.openvinotoolkit.org/latest/_tools_downloader_README.html
I will reinstall python 3.7 and run the Install_prerequisites script again
Kind regards
Frank

Dear Domoney, William,
Wow. I guess you can really teach an old Intel dog new tricks. Thanks for correcting me regarding converter.py !
I will reinstall python 3.7 and run the Install_prerequisites script again
I think the above is a great idea.
Let me know the status !
Thanks,
Shubha

So nearly there. R3 on Raspberry pi almost works
Human pose estimation demo dies on "Corrupted size vs previous size on consolidation"
Kind regards

Thanks
I did a demo on Raspberry Pi yesterday and will build a pool of applications from Open Model Zoo at an International Conference in North Africa in a month.
I will rebuild from scratch and make sure everything works on Pi.. Human Pose Estimation on the PC as a real hit with the kids yesterday.
Kind regards
Frank
