STM32N6 model accuracy benchmark

Dear ST Team,I would like to ask whether you provide any tools or recommended workflow to measure the accuracy drop of a neural network when converting a .tflite model into the STM32 binary format using STM32Cube.AI.I am looking for a simple way to c...

What's the newest ONNX Runtime version that the X-CUBE-AI 10.2.0 supports?

I want to train some small DL models with Nvidia's RTX 50 series GPU, which can work properly only with CUDA 12.x. I've learned that the CUDA 12.x is only compatible with ONNX Runtime 1.17.x or newer version. So I want to know if the X-CUBE-AI 10.2.0...

How do I run an RNN series model file?

HelloI'm considering running an LSTM(RNN-based model) model file, on the STN32N657 NPU.However, I understand that the NPU is CNN-based and therefore cannot run on it.Is there a way to run an LSTM model file on the NPU?I understand that theoretically,...
