Unable to Install Dependencies on Amazon Linux

[prestomation]

Describe the bug
I'm trying to setup AliceLG to run on a renderfarm on AWS on AmazonLinux2023 with blender 3.6

I'm using the --alicelg-install option but it's not actually doing anything

To Reproduce
Steps to reproduce the behavior:

1. run the following script on amazon linux after installing blender 3.6

mkdir -p scripts/addons
curl -L 'https://github.com/regcs/AliceLG/releases/download/v2.2.2/AliceLG.zip' > AliceLG.zip
unzip 'AliceLG.zip' -d 'scripts/addons/'
export BLENDER_USER_SCRIPTS=scripts/
blender -b --addons AliceLG -- --alicelg-install 

Expected behavior
The addon dependency install runs successfully

Screenshots
I get the following output:

[regcs]

Thank you for the detailed description, @prestomation. Is there also a side-packages-install.log in the add-on's log folder?

[prestomation]

nope! I used cat $LOG_DIR and only those other 2 log files existed there

[regcs]

Hm, ok. That is strange, because then the corresponding function is most-likely not called at all. I will prepare a small debugging version later which will do some more log entries. Please stay tuned. :)

[prestomation]

I've got the code setup so I can modify and submit using my customized version.

I've added some logging statements and it appears the 'LookingGlassAddonInitHandler' function never runs.

I was able to manually pip install the dependencies by copying what the code does. It no longer complains about missing dependencies, but of course when I go to render 'LookingGlassAddonInitHandler' still isn't running so it does nothing.

Any ideas why this handler won't run? My command looks like this:

blender --background /path/to/scene.blend --addons AliceLG -- --alicelg-render --render-output /path/to/output --render-frame 1

Hi @prestomation, thanks for your messages and sorry for not getting back to this earlier.

The LookingGlassAddonInitHandler not being called would either be a Blender bug on Linux (just confirmed it works on macOS in headless mode) or a misinterpretation because you looked at the console. By default, Alice/LG disables logging to the console at the beginning of LookingGlassAddonInitHandler to not spam the console in case other add-on's also log info. But it always writes the info to the log files. Let's try to debug this further.

Attached you find two files where I also added some more debugging statements. I also placed the above mentioned logger level update to the end of LookingGlassAddonInitHandler. Please do the following:

1. Download the modfied files (Archiv.zip)
2. Unzip and then overwrite the corresponding .py files in your Alice/LG directory
3. Delete one of your dependencies (e.g., "cv2") from your AliceLG/lib/ folder and start Blender with '--alicelg-install' flag set.
4. From your AliceLG/logs/ folder, please copy the alice-lg.log, pylightio.log, and side-packages-install.log here.

Thank you!

As an aside, are pynng, cv2, and pylightio required for a non-interactive render?

More or less, yes. These packages are needed for the interaction of emulation of Looking Glass devices and rendering quilts. Strictly, pynng is probably not strictly required because you don't communicate with Looking Glass bridge in headless mode. But it is a dependency for pylightio and it would complain, if it would not be there.

[prestomation]

Please see attached:
pylightio.log is empty and there is no "side-packages-install.log". Looking at the diff of what you gave me and then the output I see it looks like LookingGlassAddonInitHandler isn't running.

pylightio.log

alice-lg.log

Thank you, @prestomation! I figured, I forgot to change the logging level. So, there is still a chance, it is executed.

Can you try this modified version and send me the log files again?

Thanks @regcs . Unfortunately I'm still seeing no change. Also I have upgraded to blender 4.1.1 incase there was some bug on the version I was using but behavior is the same

Hm, that's bad news then. If the handler is not called at all and it works on macOS, but not on Linux, it looks rather like a Blender bug. I will try to find some time to isolate the code pieces and send you some test code. That will at least show us, if the problem is related to the app handlers or not.

In the meantime, do you have another machine to test this on?

Thanks @regcs . So the plugin works fine for me on my local windows machine and I can continue to use it and am not blocked exactly.

I am specifically trying to get it to run on a specific renderfarm service that runs Amazon Linux. There are options to run windows but this is more expensive and has other issues unrelated to AliceLG I don't really want to deal with right now. I'm fine running on my local but if you have ideas I'm all ears!

Ok, glad to hear, it doesn't totally block you. Still want to know what is causing this. I am just a bit bound here, because I cannot test on Linux myself at the moment and never used AWS.

In case you have the option to test on another Linux distribution, let me know.

Regardless of that, we will stick to the plan and I will provide you with some isolated code pieces to test. Might just take me a few days. So, please stay tuned :)
