Hi,

I was wondering if it would be possible to modify the current implementation of the model to use the DeformConv2dFunction function from MMCV instead of the official implementation from Torchvision.

The reason for this request is that the developers of MMCV have also implemented support for exporting this operator to ONNX, along with its associated ONNX Runtime operator. This would enable exporting the model to the ONNX format without relying on the current solution, deform_conv2d_onnx_exporter, which is quite slow, and would help address potential issues related to dynamic_shape handling.

Would you consider integrating or optionally supporting this alternative implementation? If needed, I’d be happy to contribute. I understand that a change of this type might require retraining the network.

Thank you for your time and consideration!

Best regards,
Álvaro.
