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?

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

 ![Screenshot 2024-07-12 at 4.27.39 PM](https://canada1.discourse-cdn.com/flex029/uploads/roboflow1/original/2X/b/bf264072e90ff8973b5e4ad4de5c69ba0f6b22e4.png)

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!
