Cant get RFFT2D to work

[naveedakhter01]

After conversion, onn.checker throws error "No Op registered for RFFT2D with domain_version of 18"

Code import tf2onnx

tflite_path = "/kaggle/input/birdnet/tensorflow2/default/1/CustomClassifier.tflite" onnx_path = "/kaggle/working/bpi.onnx" model_proto, external_tensor_storage = tf2onnx.convert.from_tflite(tflite_path, opset=18)

onnx.checker.check_model(onnx_path, True)

Output
