logging runs in buffered mode on python3.7 #60

Open wjgeorge opened 3 years ago

apparently a small chnage in python3.7, stderr is buffered so output to logfile will only happen when the buffer is full. These two command will perform differntly

sudo python3 ${HOME}/CommanderPi/src/main.py ${HOME}

vs

sudo python3 ${HOME}/CommanderPi/src/main.py ${HOME} > logfile.txt
