Error converting to onnx

I'm trying to convert the pytorch model to onnx, doing: `python -m spai export-onnx`, but I'm getting the following error: `torch._dynamo.exc.Unsupported: 'skip function MFViT.export_onnx.<locals>.ExportableMFVit.forward in file .venv\lib\site-packages\torch\onnx\_internal\fx\dynamo_graph_extractor.py'`.

Do you know what can be causing this problem?

Thanks in advance
