Updates to the TFLM Makfile that are not backwards compatible

System information

• OS Platform and Distribution: Linux Ubuntu 20.10
• TensorFlow version: 2.4.1
• Python version: 3.8
• CPU Intel Core i7
• GPU: NVIDIA GeForce GTX
• STM32CubeIDE-Lnx: 1.3.0
• STM32 Nucleo-64 development board

Describe the problem

I would like to run the Makefile in the Tensorflow Lite for Microcontrollers directory in order to run inference on ST microcontroller above. My problem is that I cannot use the
TAGS =”portable_optimized” command line option /cc @advaitjain

Source code / logs

tensorflow/lite/micro/tools/make/Makefile:61: *** The TAGS command line option is no longer supported in the TFLM Makefile..

Thanks in advance.

The portable_optimized kernels have been removed for some time now. You can remove TAGS=portable_optimized from your command line and things should work as before.

Also, since you're using an stm32f4 board, you might also want to try OPTIMIZED_KERNEL_DIR=cmsis_nn to get optimized implementations for some of the kernels.

Did you generate sample project to test with the stm32, if so what was the make command you used

Hi, I used this command: make -f tensorflow/lite/micro/tools/make/Makefile (from https://www.digikey.com/en/maker/projects/tinyml-getting-started-with-tensorflow-lite-for-microcontrollers/c0cdd850f5004b098d263400aa294023)
