X-CUBE-AI error while analyzing a Keras model in Ubuntu

The model I've been using for a year in CubeIDE 1.6.0 on a laptop cannot be analyzed now on a PC in the latest CubeIDE 1.6.1 while using the same X-Cube-AI v5.1.2. (I've tried the most recent v6.0.0 - the same error.)

Ubuntu 20.04 (both laptop and PC).

Model: https://github.com/Shahnawax/HAR-CNN-Keras/blob/master/model.h5

Error log on a PC:

Analyzing model 
/home/dizcza/STM32Cube/Repository/Packs/STMicroelectronics/X-CUBE-AI/5.1.2/Utilities/linux/stm32ai analyze --name network -m /home/dizcza/Downloads/model.h5 --type keras --compression 1 --verbosity 1 --workspace /tmp/mxAI_workspace505704300370625560993010444853274 --output /home/dizcza/.stm32cubemx/stm32ai_output  
Neural Network Tools for STM32 v1.3.0 (AI tools v5.1.0)

It does not produce a log file (the command ends with a nonzero exit code), therefore I cannot post it.

The same model has been successfully analyzed today on a laptop Ubuntu 20.04 beside me.

It's even worse! Now I cannot simply open an .ioc file anymore! (PC only.)

I've encountered the same error while opening this .ioc file (https://github.com/dizcza/stm32f446-FunduMoto/blob/nn/stm32f446-FunduMoto.ioc) in both CubeIDE CubeMX perspective and the latest STM32CubeMX 6.2.1 (standalone).

You should have more output in the STM32CubeMX log file located at ~/.stm32cubemx/STM32CubeMX.log

Regards

I've reproduced the crashing stm32ai command line on Ubuntu 20.04.2 LTS

It is working fine on Ubuntu 18.04 LTS

Thanks for reporting this issue, I don't have the root cause yet but I'll let you know if there is a workaround

can you confirm that your CPU doesn't support avx instructions ?

cat /proc/cpuinfo | grep avx

if you have nothing in the output it means it doesn't support those extensions.

Recent versions of Tensorflow uses avx instructions by default.

On a machine without avx support tensorflow will not work (my old linux machine doesn't have avx support).

A colleague of mine ran stm32ai on Ubuntu 20.04 without any problem but his CPU supports avx instructions.

Exactly, my CPU doesn't support avx instructions, unfortunately.
