Using Pillow with AppDaemon4

I am trying to use Pillow for processing images in AppDaemon. I’ve been at it for a while now. AppDaemon says Pillow is installed but I cant import it with a script.

I am using HASIO and the Supervisor install of AppDaemon4 (version v0.7.0). I’ve had that running for a while and have 4 or 5 other scripts that run just fine.

I now added Pillow to the config tab in supervisor

Here is my AppDaemon start up log, it now shows Pillow installing successfully. But I note that I get this installing message about downloading and installing Pillow every time I restart AppDaemon. So I wonder if its really getting registered in the module list?

Help is greatly appreciated.

But when I run my app, I get errors loading the module. Here is my app and the AppDaemon Error log. If I comment out the PIL import the app initializes, so there is no other issue other than loading the module.

from PIL import Image

Hi there,

This seems to be related to this topic, but with Pillow instead of numpy.

Alpine has a system package called py3-pillow. So configuration should look like this:

  - py3-pillow
  - ffmpeg
python_packages: []
init_commands: []

As you can see Pillow should not be included as a python package, but as a system package now.

Thanks! That’s brilliant.
I’ve proposed a change to the documents since they happen to show Pillow as an example.

I now have another problem. I can’t access the camera data from home assistant (in the /media folder). I kind of feel stupid - of course, its a separate docker container.

Glad you got it working. I opened a PR to propose the change in the addon documentation:

That I am not sure, but I believe that just /config is attached to the docker container.


Yes, by my experiments only /config is available by default with the HASIO addon
