ModuleNotFoundError: No module named 'past'

Hello,
I have the WeatherRack2, and using an RPi 4, I am able to get the raw
data feed from the unit to stream.
I have been able to save console output using tee to a txt file locally.
I am not able to get the dashboard to install though.
rtl_433 is installed and I have run "git pull" on it.
I am trying to install WeatherSense to the RPI
(https://github.com/switchdoclabs/SDL_Pi_WeatherSense) and am stuck on
running:

pi@computer:~/SDL_Pi_WeatherSenseWireless $ sudo python3
WeatherSenseMonitor.py
Traceback (most recent call last):
File "WeatherSenseMonitor.py", line 6, in <module>
import wirelessSensors
File "/home/pi/SDL_Pi_WeatherSenseWireless/wirelessSensors.py", line 18,
in <module>
import util
File "/home/pi/SDL_Pi_WeatherSenseWireless/util.py", line 4, in <module>
from past.utils import old_div
ModuleNotFoundError: No module named 'past'

Any help would be greatly appreciated.
Thank you
