Convert with onnx slower then wts

[YaroslavPavlovich]

I converted my custom YOLOv5 model to .onnx using the export_yoloV5.py script. I then ran my program on a Jetson TX2 with the new version of DeepStream-Yolo, and here are the FPS results:

The FPS is unstable (I can fix that), but the main problem is that it’s slower than the previous version (10 FPS vs 12 FPS). If I use the older version with commit ab6de54, and convert using gen_wts_yoloV5.py, I get the following results:

I only changed the conversion script and the .so file. Is this performance difference normal, or have I made a mistake?

For conversion on Jetson, I used:

python3 export_yoloV5.py -w yolov5s.pt --batch 2 --simplify --opset 12

I also tried:

python3 export_yoloV5.py -w yolov5s.pt --batch 2 --opset 12

but there was no change. The Deepstream version on Jetson is 6.0.

Did you try with higher opset (17 for example) + simplify? The ONNX support is easiest for me to keep updated on the repo, that's why it's used now.
