I am following the tutorial with these command:
make -f tensorflow/lite/micro/tools/make/Makefile TAGS="DS_CNN Simple_KWS_Test" generate_kws_cortex_m_mbed_project
cd tensorflow/lite/micro/tools/make/gen/linux_x86_64/prj/kws_cortex_m/mbed/

change the mbed-os.lib version :
https://github.com/ARMmbed/mbed-os/#60cbab381dd2d5d860407b1b789741275012a075

mbed config root .
mbed deploy
mbed compile -m K64F -t GCC_ARM

and then t get an error:

How can I solve this problem?

commented

Can you try a fresh clone/install using regular Python and pip environments in place of Conda?

It is also possible you are missing some board specific drivers/utilities; these are typically added via mbed add:

mbed add https://os.mbed.com/teams/ST/code/BSP_DISCO_F746NG/

What is the full name of your board? I do not see a counterpart for K64F but let me know if using pip in place of conda environments does not resolve the issue and I can investigate further.

What command do you run to change the mbed OS version?

@liabar01 Thanks for you advice.
I reconfigured the environment using Conda and rerun succeed.

Hello,
How did you exactly solve this particular problem? I am also stuck with this now and I can not find a solution.
Thanks in advance.
