DASH! micropython test.py no module named 'OmegaExpansion'

[LightSwitch]

root@Omega-C592:~# micropython test.py
Traceback (most recent call last):

but...

root@Omega-C592:~# python test.py
-0.795

works 4.0.

I'm using the dash, so I want to use the lv_micropython lib to create the gui. I've had several issues so far and this is just one of them I've created a posting for. The other one is here:
https://community.onion.io/topic/4282/omega2-dash-adc-exp-python-not-connecting/3?_=1601154474163

What do I have to do to get the microphython to recognize the OmegaExpansion package that is present?
I already also did this instruction: opkg install micropython-lib --nodeps

The code for test.py is below

from OmegaExpansion import AdcExp

class Test:
def init(self):
self.adc = AdcExp.AdcExp(address=0x48);
print(self.adc.read_voltage(0));

Test();

@LightSwitch The ADC Expansion package is for Python only, it won't work for micropython.

To interact with the ADC Expansion with micropython, I recommend calling the adc-exp command-line tool from micropython.
