dynamic_axes onnx export

[IlkayW]

Hi,

is the dymaic_axes option for onnx export supported?
I always get fixed input shape of [1,3,560,560], when I do this:

``
import rtfdetr

model=rfdetr.RFDETRBase()
model.export(dynamic_axes=True)
``

Greetings,
Ilkay

I converted the model to ONNX with dynamic batch size and image size, see https://github.com/zhouzq-thu/DETR-ONNX.
