YoloNAS with dynamic input shape

[kevinzezel]

I'm not able to convert the model to onnx with dynamic input shape.

from super_gradients.training import models
net = models.get("yolo_nas_s", pretrained_weights="coco")
models.convert_to_onnx(model=net, input_shape=(3,640,640), out_path="yolo_nas_s.onnx")

Is there any flag I can put in the above code?

I tried to convert using the ultralytics package, but without success. Only works with yolov8.

yolo task=detect mode=export model=yolo_nas_s.pt format=onnx dynamic=True
