when i convert model of torch to onnx, the issue exist, which is so sad,
onnx exporter has an argument called opset_version
which you can use to see if this feature was supported in an older or newer opset torch.onnx — PyTorch 1.11.0 documentation
You can also manually scan this folder here to see if your op exists pytorch/torch/onnx at master · pytorch/pytorch · GitHub
And if it doesn’t please make a feature request on pytorch/pytorch or implement your own custom op
