skl2onnx.common.exceptions.MissingShapeCalculator: Unable to find a shape calculator for type '<class 'sklearn.ensemble._iforest.IsolationForest'>' #533

Hello,

I am running skl2onnx 1.7.0 and see the following when I want to dump IsolationForest model:

skl2onnx.common.exceptions.MissingShapeCalculator: Unable to find a shape calculator for type '<class 'sklearn.ensemble._iforest.IsolationForest'>'.
It usually means the pipeline being converted contains a
transformer or a predictor with no corresponding converter
implemented in sklearn-onnx. If the converted is implemented
in another library, you need to register
the converted so that it can be used by sklearn-onnx (function
update_registered_converter). If the model is not yet covered
by sklearn-onnx, you may raise an issue to
https://github.com/onnx/sklearn-onnx/issues
to get the converter implemented or even contribute to the
project. If the model is a custom model, a new converter must
be implemented. Examples can be found in the gallery.

skl2onnx from master works fine.
