Crash/hang: Can't start chainner at al // ModuleNotFoundError: No module named 'attr'

[sbrl]

Information:

• Chainner version: 0.24.1
• OS: Ubuntu 24.04
• uname -a: Linux Starfall 6.8.0-45-generic #45-Ubuntu SMP PREEMPT_DYNAMIC Fri Aug 30 12:02:04 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux
• (system) python --version: Python 3.12.3

Description
On startup, chaiNNer claims that it is endlessly starting the backend process:

...running it in the terminal however results in a much more useful error, as described in the logs suggestion

.....this suggests that the attr package is missing, but I already have python3-attr installed (log #2).

I tried installing the attr package with pip3 install attr --user --break-system-packages, but frustratingly this did not change the error.

I did see #3010, but while may be related to this bug seems distinctly different. It does suggest that chaiNNer has it's own isolated python environment, which seems to be at fault here.

To this end, I navigated to ~/.config/chaiNNer/python/python and manually run: bin/chainner_pip3 install attr --verbose, which correctly installed the package inside the environment.

This resolved the error, but resulted in another similar error (log 3), which claims ModuleNotFoundError: No module named 'idna'.

To this end, my findings suggest that your 'isolated environment' is completely broken, and does not serve the intended purpose.

Furthermore, since you do not have a CLI flag to force chaiNNer to use the system packages one is left without a workaround in case of issues.

Full list of packages I hackily installed using the above method:

INSTALL attr
INSTALL idna
UNINSTALL attr
INSTALL attrs

...then I can start it, but the viewer node says "image not valid" or something to that effect.

Restarting with the system version of Python and applying this workaround results in log #4.

....so I'm at a standstill here. While chaiNNer looks like a fabulous concept, I cannot get it to run.

Some suggestions of alternative bundling solutions:

• AppImage?
• Docker?
