Model Optimizer ONNX conversion error

Hello Intel Developer,

I train deeplab v3+ with Resnet-18 on MATLAB (deeplabv3plusLayers()) and export to ONNX format.

While conversion, Model Optimizer outputs following error.

Which is wrong, MATLAB's ONNX or Model Optimizer ?

I attach compressed ONNX file.

Thank you.

I solved conversion error.

My onnx does not contain batch normalization layer's parameters.

Because MATLAB does not support intermediate result for BN layer.

See MATLAB Answers

Thank you
