Investigate the PyTorch vision source code for deformable convolution implementation, specifically the torchvision.ops.deform conv module. Check if the module has an ONNX symbolic registration in torch.onnx.symbolic opset or similar. Also, test exporting a simple model containing deform conv to ONNX to see if it works. Review any existing discussions in the issue comments for hints or workarounds.
