Any help?

I’m running into the same problem on my raspberry pi, by any chance did you find a solution?

@Aidan_Montag @Rishabh_verma did you two use Modify Classes on the generated versions these models are being deployed from?

I’m having a similar error (below) and I did use the “Modify Classes” feature on my DeerWatch dataset. Is there a step I can take to modify the code and make this work?

[patch]

I had the same error. It turns out the “model” parameter in the RoboflowOak function is wrong.

Click on these three dots on your model page and you should see “Copy Project Id”. Click on it and paste it into the “model” parameter.

Hopefully this helps!
