  I am currently trying to set up a dht humidity sensor with my raspberry pi 4. I followed the instructions from the adafruit_dht Github using the setup.py file but I get this import error when I run my test file. I have tried installing it using ```sudo pip3 install Adafruit_DHT``` and I get this error

  Here you go, https://chandlerhometemp.z22.web.core.windows.net/index.html. I modified the Adafruit_Python_DHT scripts a little bit to call my azure function API (just a HTTP POST call) instead of printing the data in console. Here's the (asp.net core) controller code https://github.com/chandde/misc/blob/master/HomeTempFunc/HomeTempFunc/Temperature.cs, same endpoint supports POST (for uploading) and GET (for the static web server to pull data from DB)
