Hello,  
I created a first version (yolov12) of my model with 2000 pictures.  
When i test it with a picture belong to the training images, it doesn’t detect objects !  
Is it normal ?

I thought it will always detect objects for all trained pictures…

And i created a Roboflow instant model, the results are better.

Any idea ?  
Thanks

How are you testing the model? I looked at your project on Universe and the model works well there [How to Use the VF\_Faucet Object Detection API](https://universe.roboflow.com/vffaucet/vf_faucet/model/1?image=https%3A%2F%2Fsource.roboflow.com%2FakPQNlsJltaSXfTvK24CohCSPqz2%2FcXrAuCbTLNAwyf0S0vaY%2Foriginal.jpg)

Hi,  
I tested the model directly in the roboflow interface, on the Universe and with API. Same bad results.  
Example:

I’d suggest looking at your dataset splits and class representation to make sure they are balanced [VF\_Faucet Dataset and Pre-Trained Model by VFFaucet](https://universe.roboflow.com/vffaucet/vf_faucet/health)

How can i use “roboflow instant” with API [detect.roboflow.com](http://detect.roboflow.com) ?
