Azure Percept eye module problem

Hello my Vision module on my IoT Azure percept DK is not working. Just seemed to have stopped. Please see device logs on eyemodule below. Any help would be great!

@AshokPeddakotla-MSFT - This might be something different than the highlighted "too many levels of symbolic links" error.

Hi @TomFanara-5555 - were you running a custom model when this happened? If so, had you made any changes to that model?

yes I deployed a custom vision model

@TomFanara-5555

It looks like the model.zip file that is being deployed to the dev kit has an issue. Can you validate that the zip file and its content is not corrupted. Make sure that you can access the URL and download it from your browser.

From the logs it looks like you are using ssd_mobilenet_v2_coco.blob model file which is generated from this transfer learning notebook azure-percept-advanced-development/transfer-learning-using-ssd.ipynb at main · microsoft/azure-percept-advanced-development (github.com).

My custom vision model worked great for a week then maybe after I deployed the vision upgrade it broke it not sure. It was an upgrade from Azure Percept Studio under the device General tab

Hi @TomFanara-5555 - thanks for checking this. I think it rules out any issues with the hardware, software or firmware. All indications is it is an issue with the model.zip which we are discussing in the other part of this thread.

Yes I think you are right. Here is the image URL from the device screen. Is this the right place to get the model.zip? It just redirects ro a git hub page for registered containers if I browse it!

Thank you so much sir as I have upgraded 4 times using USB!

@TomFanara-5555 - I'm so sorry you've had to do that! I don't think any more updates are necessary. I've got some engineers investigating the model.zip. Hopefully we'll have a solution soon.

ok its all working even my custom model see below. Don't know exactly what fixed it. Maybe there was a breakage in the docker image or container deployment?
