Convolutional layers with groups cannot be converted properly

[LaCandela]

I tried to convert a keras model that contains 2D group convolutions and in the resulting ONNX file the group parameter is always 1 even though it should be different.

I am using:
Python 3.6.9
Tenorflow 2.3
keras2onnx 1.7.0

I also tried to install keras2onnx from source (v1.8), it didn't help.

have you also use onnxconverter-common from source ?
