Octolapse rendering fails

hemna commented 3 years ago

Octolapse is able to take snapshots, but when it tries to render the timelapse it fails

The logfile shows

Looks like this is related to the rendering overlay. There was a bug I fixed relating to this. See this zip link you can use to install and test via the plugin manager->Get More->From url... in OctoPrint settings(you should be able to re-render via the 'Failed Renderings' button on the tab after you install and reboot): https://github.com/FormerLurker/Octolapse/archive/8cae0c9d8f9b11d7a55c3d6fb04956931636429c.zip

Installed the zip and get the same exact error.

I've narrowed it down to the call to features.version_module("freetype2") It's returning None, which causes parse_version to puke.

FormerLurker commented 3 years ago

Ug.. this is some odd python version incompatibility within pillow that I've not seen before. You'll notice that the error is happening entirely within pillow itself:

File "/octoprint/plugins/lib/python3.8/site-packages/PIL/ImageFont.py", line 173, in __init__                                                 │
│    freetype_version = parse_version(features.version_module("freetype2"))

Did you upgrade python somehow after Octolapse was installed?

Edit: not a python 2/3 thing after all!

FormerLurker commented 3 years ago

Ok, I did a bit of research. I'm guessing you aren't using OctoPi, right? It could be that the libfreetype package isn't installed on your system, which means there is no text layout support. You install that package, remove pillow, then re-add pillow (make sure you use the correct virtual environment!) and see if that helps.

I am running everything inside a container on my rpi.

Docker? I'm not as familiar with that as I should be. I should probably spend a couple days working with it.

hemna commented 3 years ago

I tried installing freetype-py and pillow to fix it, but it didn't.

FormerLurker commented 3 years ago

You need to install libfreetype-dev via apt-get I believe.

hemna commented 3 years ago

I tried and that doesn't work :(

FormerLurker commented 3 years ago

Hmmm. Maybe the kind people who developed pillow may have an idea. In any case, I will see what I can find.
