error:tensorflow/lite/micro/tools/make/Makefile:61: *** The TAGS command line option is no longer supported in the TFLM Makefile.解决方案
参考：https://github.com/tensorflow/tensorflow/issues/46667
原因：TAGS已经废弃，将这个删掉或者改成OPTIMIZED_KERNEL_DIR=cmsis_nn
make -f tensorflow/lite/micro/tools/make/Makefile TARGET=mbed OPTIMIZED_KERNEL_DIR=cmsis_nn generate_hello_world_mbed_project这样就不会报错咯
