[Solved] Humidity Sensor and Python


Good Afternoon and Happy Friday!

I am currently trying to work with the humidity sensor using the python matrix-lite packages. I am new to python and have more experience with js/c#/java.

I was able to get the sensors running by using this code : https://github.com/matrix-io/matrix-lite-py
My code is pretty basic

import halSwig as hal
from time import sleep

# Print exported objects/functions

## Humidity Example ##
humidity = hal.humidity()
while True:
	data = humidity.read()
	print("Humidity: ", data.humidity)
	print("Temperature: ", data.temperature)

Now what i am trying to do is take this logic and join it with the google-assistant-matrixio hotword.py logic.
When I add the below lines to the hotword.py file I get an error.

import halSwig as hal
from time import sleep

“Traceback (most recent call last):
File “/home/pi/google-assistant-matrixio/google-matrixio-assistant-hotword”, line 7, in
from matrixio.hotword import main
File “/home/pi/google-assistant-matrixio/matrixio/hotword.py”, line 29, in
import halSwig as hal
ImportError: No module named ‘halSwig’”

Why would one scrpt have no issues finding halSwig and then another script have an issue?

hmm maybe your first code uses python3 installed with pip3 and google-assistant the older python2.7 / pip(2), or it is running in a virtual env?


python 3 should be what both were using as that is what is pre installed on this. I did install the google assistant in a virtual environment but the sensor project wasn’t.

I went back into the virtual environment and installed the matrix lite packages and everything seems to be working now.
