Error in compile tflu-kws-cortex-m/kws_cortex_m

[charlescho64]

Hello...

I am following with guide in this site ii order to deploy AI model to STM32F4. But I have the problem in compile.
This issue is the same to other issue(Error in compile tflu-kws-cortex-m/kws_cortex_m #61) but the solution is not open.

I am in problem with compile under cross compile 9.3.1 and python 3.9.15 on osx mac.

From the issue you linked to the error seems to have been caused by the Python environment. Are you able to try creating a fresh Python environment, installing mbed-cli and trying building again?

I got same error. What is your Python version. Does it need a specific Python Version. Or, is there any requirements file for conda enviroment?
