daiarg版 detect.py は wiring2 を使う。
wiring2 は，インストールされていない：
<![CDATA[(venv) $ pip show wiringpi2
WARNING: Package(s) not found: wiringpi2]]>
プログラム中の wiring2 を wiring に変更すると，つぎのエラーが返される：
<![CDATA[(venv) $ ./detect_daiarg.py
pinMode PWM: Unable to do this when using /dev/gpiomem. Try sudo?]]>
wiringpi のバージョンの変更では，エラーは無くならない：
<![CDATA[(venv) $ pip show wiringpi
