Implementation Error analyzing ONNX model

[Robin1]

Hi,

I'm trying to analyze my ONNX model (converted from PyTorch) in STM32 X-CUBE-AI version 8.1.0. But it shows this error: NOT IMPLEMENTED: Unsupported layer types: Expand.

I can't find a solution on Google. What do I need to do to analyze/import my model succesfully? 

Kind regards,

Robin
