Depthai: [BUG] RuntimeError: Model compiler failed! Not connected to the internet?

[marmalodak]

What else is needed to run the demo? As far as I can tell, I've installed everything as documented.

I've run this several times to see if it was a transient issue with whatever service is running at host='69.164.214.171', port=8083. I get the same results each time.

So the system automatically downloads the beauty models for you but you could instead manually download the models per the documentation for each example here:

https://docs.luxonis.com/projects/api/en/latest/samples/08_rgb_mobilenet/#setup

Thanks for answering. I'm unclear about what I'm downloading.

Do I download each example? Or is it the .blob file that I download?

[Luxonis-Brandon]

So you can download the whole example and run it, or download just the model and use it with other code. CC: @Erol444 in case you have other advice here as well.

Hello @marmalodak ,
it seems that our blobconverter API wasn't working at the time you were trying to access it. We apologize for the inconvenience. Could you try accessing the 69.164.214.171:8083 from the RPI with a web browser? Could be that something is blocking the request...

Just tested it and it seems to work for me:

Yesterday evening the depthai demo worked for me. I was able to connect a camera and see some things being detected.

I haven't yet had time to figure out how to cache all the necessary files locally.

Thanks for helping.
