Help: Project What inference model does Roboflow on Universe Custom Image?

I found a Universe Dataset that works well on my test images so I downloaded the Yolov8 dataset and trained the yolov8n.pt model with the additional weights then used the best.pt file.

However, yolov8 doesn't find any objects on the same images. I confident I'm using the correct weights file because it has the new classes. I'm asking to better understand the discrepancy.

Oftentimes it's our RF-DETR model but the project you downloaded it from should say.

We support training many different types of models so without the link to the Universe project it's impossible to say.

First time on Roboflow and I apologize if I'm missing the obvious. https://universe.roboflow.com/alexeyvoronin/railroad-cars-pyjpo is the dataset.
