"""
purpose: Used to simply measure CPU performance by running several basic models.
how to use: python3 cpu_evaluation_tools.py --help for more details, now need to args:
    --load_and_run_file: path of load_and_run binary, please refs to ../scripts/cmake-build/BUILD_README.md to build it.
    --models_dir: path of model directory.
how to config test device info: config device[name/login_name/ip/port/thread_number].
