base example gives error

right after a clean install on rpi3

(env) pi@raspberrypi:~/AIY-projects-python/enviroplus-python/examples $ python compensated-temperature.py 
compensated-temperature.py - Use the CPU temperature
to compensate temperature readings from the BME280 sensor.

same story for python3 it seems

Thanks for pointing this out. Hopefully fixed! I'm caught up in the Pi 4 chaos at the moment.

Out of interest, what do you get if you python --version since I would have expected this to work in Python 2.x.

with python3.7 it works if you put this to line 29:
output = output.decode('utf-8')

i can confirm that it now works on my raspberry. thanks!
