ImportError: cannot import name '_gi' using python3-gi on RPi Zero

Straight to it:

23.10.19 20:20:23 (+0100)  main    File "server.py", line 1, in <module>
23.10.19 20:20:23 (+0100)  main      from gadget import Gadget

23.10.19 20:20:23 (+0100)  main      from . import _gi
23.10.19 20:20:23 (+0100)  main  ImportError: cannot import name '_gi'

I've been toying with the Alexa Gadgets Toolkit which uses python3-gi (dependencies it installs can be found here) and have hit a snag.

For context, I'm using Balena's Raspbian with Python Docker image, on a Pi Zero W. It just seems to completely fail when launching because it can't load the _gi module.

I've tried various Python version (3.4, 3.5, 3.6, 3.7) with no avail, and also tried installing various dependencies manually, using pip via python -m pip to ensure the right pip was used, etc. No luck. Python 2.7 doesn't work at all either due to an encoding issue in the AGT library, however it looks like it's expected to be used with 3.x anyway.

Solution!

It turns out that the .so module for GI simply needed to have the "34m" renamed to "36m", so I added these to my Dockerfile and it runs just fine now

RUN sudo mv /usr/lib/python3/dist-packages/gi/_gi.cpython-34m-arm-linux-gnueabihf.so /usr/lib/python3/dist-packages/gi/_gi.cpython-36m-arm-linux-gnueabihf.so

RUN sudo mv /usr/lib/python3/dist-packages/gi/_gi_cairo.cpython-34m-arm-linux-gnueabihf.so /usr/lib/python3/dist-packages/gi/_gi_cairo.cpython-36m-arm-linux-gnueabihf.so
