Unable to create project with STM32 Cube AI studio

[chanchal94]

I am unable to generate project [ consisting of .onnx format - model is using logistic regression] with the help of STM32 cube AI studio . I have attached the error in screenshot below. Can we not implement simple models like logistic regression while doing real time deployment in STM32N6570-DK? Kindly help.

Hi ​@chanchal94,

 

As stated in the error message, the ONNX layer LinearClassifier is not supported on the N6 using the NPU.

You can find the list of supported layers here:

https://stedgeai-dc.st.com/assets/embedded-docs/stneuralart_operator_support.html#overview

 

In short, the NPU is primary made to accelerate convolutions. So I would advise to look for convolutional models that could perform regression (TCN maybe?) or if you don’t work with very big inputs, NanoEdge AI Studio could be interesting for you as one of the supported use case is Regression.

Have a good day,

Julian
