Timelapse previews not generated with Pillow 10.0.0

[CodedSakura]

Version of Octolapse

Octolapse Version: 0.4.3

Version of OctoPrint

OctoPrint Version: 1.9.1

When you ran into the problem, did you have diagnostic logging enabled?

Diagnostic Logging was Enabled: yes

What were you doing when the problem occurred

1. Install OctoPi (1.0.0) on a raspberry Pi (3B+)
2. Add Octolapse plugin to OctoPrint
3. Configure Octolapse
4. Start printing with Octolapse enabled

What should have happened?

Timelapse preview should display the last snapshot

What happened instead?

Timelapse preview says "No snapshots have been taken...", but the Sanpshot Count displays a non-zero number.
The timelapse also renders succesfully after print finishes.

Self diagnosis of the problem

Looking at the plugin_oclolapse.log file, at line 2202 it is visible that Octolapse failed to generate a thumbnail
from the snapshot. This seems to be caused by PIL, as the error says AttributeError: module 'PIL.Image' has no attribute 'ANTIALIAS'.

Python version: 3.9.2
Pillow version: 10.0.0

PIL.Image.ANTIALIAS was incidentally removed in Pillow 10.0.0, but was already deprecated for a while.

This issue repeats for each time Octolapse tries to generate a preview. (L2202, L3560, L4898, L6198, L7480)

Encountered this as well, and was able to fix this by updating snapshot.py, replacing Image.ANTIALIAS with Image.Resampling.LANCZOS.

confirmed the above change works.

Hi,
might be a dumb question, but what do I need to do? Install the sane plugin? Rename the Image.ANTIALIAS file to Image.Resampling.LANCZOS?
I'm a bit confused.
Thanks

Same issue here, but i don't know how to make this change, any short tutorial?

I found it while searching for something else. You need to edit a file on your Octoprint system.
I think it is /boot/octopi.txt but I'm not sure and I can't have look at the moment I have no access to my system and I can access it earliest in 7-14 days. In this file you need to change the entry accordingly. So you don't need to rename any file.

Thought i need to change the name in snapshot.py itself, but wasn't able to find it, also on octopi.txt i wasnt able to find anything, there are just some settings for the webcam Octopi.txt

I need to have a look, but at the moment I'm in hospital so, that isn't that easy.

Fairly easy fix. If you open the octolapse log file you will see exactly where the error is located. Here is what I did.

1. ssh to octopi
2. cat or less plugin_octolapse.log (this will show where the error is occurring in the python code
3. using your favorite editor, change Image.ANTIALIAS file to Image.Resampling.LANCZOS

$ ssh username@octopi
$ less ~/.octoprint/logs/plugin_octolapse.log

you should see something like this:

YYYY-MM-DD hh:mm:ss,m - octolapse.snapshot - ERROR - An unexpected exception occurred while post-processing images for the Webcam - Default OctoPi 0.16.0 camera.  See plugin.octolapse.log for details
Traceback (most recent call last):
  File "~/oprint/lib/python3.9/site-packages/octoprint_octolapse/snapshot.py", line 485, in create_thumbnail
    img.thumbnail([basewidth, hsize], Image.ANTIALIAS)
AttributeError: module 'PIL.Image' has no attribute 'ANTIALIAS'

Next edit the file shown in the error. Should be the line number shown above.

$ vi ~/oprint/lib/python3.9/site-packages/octoprint_octolapse/snapshot.py

As mentioned above: `Rename the Image.ANTIALIAS file to Image.Resampling.LANCZOS'.
That should get you there.

Thanks for that one, will try it out.

Doesn't sound that good, get well soon :)

I've submitted a Pull Request to update this directly in the plugin. When testing with my local machine everything works great now.

[rickgode]

I tried the less ~/.octoprint/logs/plugin_octolapse.log but didn't have any errors. So I guess mine isn't the same issue. What I'm seeing is my timelapse preview is of something I printed before the last update. It won't change. Although the plugin seems to be working after the last update. Thoughts?

Can u upload the octolapse log?

Also i did this "fix" today & the preview is now working👍🏼

[rickgode]

Mine doesn't seem to be the same issue, it just doesn't update the preview. The image is from the last print before I updated octolapse to the latest version

I've uninstalled octolapse and will attempt reinstalling it.

plugin_octolapse.log octoprint.log

Could be still the same issue, that log is pretty clean, did you log everything/errors? And start a print with it?

[mattaster]

This seems like a different issue than #917, I'd suggest a new issue to keep things clean.

[rickgode]

I can confirm now, that my issue was the same others on this thread and the renaming the Image.ANTIALIAS to Image.Resampling.LANCZOS did the trick, but mine was a tad different (and I am total n00b in Linux) Oh and vi is the DEVIL

I typed in the less ~/.octoprint/logs/plugin_octolapse.log and got a similar message as the above post at line 485, but my location of the snapshot.py was different so I had to type the stuff below to find it

vi /home/pi/OctoPrint/venv/lib/python3.8/site-packages/octoprint_octolapse/snapshot.py

Then the arrow keys and such don't work the same in vi (because it's the DEVIL)

So I actually edited it in nano like this

nano /home/pi/OctoPrint/venv/lib/python3.8/site-packages/octoprint_octolapse/snapshot.py

Thanks!

[gnodabb]

Glad you were able to find and fix the issue!

Oh and vi is the DEVIL

lol... First time using it is definitely an awakening. The nice thing about vi is that it's always there. And, if you use it daily you get used to it very fast.

Just to update, according to google Image.Resampling.LANCZOS is also now depreciated as of Pillow 10.0 and should be replaced with Image.LANCZOS

From Google Bard -

No, Image.Resampling.LANCZOS and Image.LANCZOS are not the same. Image.Resampling.LANCZOS was introduced in Pillow 9.0.0 as a new way to specify resampling filters, while Image.LANCZOS was the original way to specify the Lanczos resampling filter. However, Image.Resampling.LANCZOS was deprecated in Pillow 10.0.0, and Image.LANCZOS is now the recommended way to specify the Lanczos resampling filter

[idaband]

This fixed the issue for me as well. Will this be implemented in the next release by chance?

[ninjamojo]

Going to try to get this added today. I think there is a PR I need to merge.

awesome saw the change in the release this issue can be resolved.

[FormerLurker]

Thanks for responding @idaband! @CodedSakura or anyone else, can you verify the issue is resolved after updating to the latest release?

[CodedSakura]

can confirm, the issue is fixed in the latest release!

Hi,
Having this issue creating thumbnails

Traceback (most recent call last):
  File "/home/pi/oprint/lib/python3.9/site-packages/octoprint_octolapse/snapshot.py", line 339, in process
    self.create_thumbnail()
  File "/home/pi/oprint/lib/python3.9/site-packages/octoprint_octolapse/snapshot.py", line 484, in create_thumbnail
    raise SnapshotError(
octoprint_octolapse.snapshot.SnapshotError: snapshot-thumbnail-create-error: Create Thumbnail - An unexpected exception occurred while creating a snapshot thumbnail for the Webcam - Default OctoPi 0.16.0 camera.  Check the log file (plugin_octolapse.log) for details. - Inner Exception: module 'PIL.Image' has no attribute 'ANTIALIAS'

Printing does not start unless you turn off Octolapse. As I see it happens in gcode files that have tumbnails.
