ImportError: cannot import name '_imagingft' from 'PIL' #8273

Closed bryankaplan closed 4 months ago

bryankaplan commented 4 months ago

Goal

Ultimately I'm trying to run detectron2. I've isolated the Pillow problem separate from detectron2, but that goal impacts my installation, as noted below.

Steps to Reproduce

On Void Linux:

$ python -m venv venv
$ . ./venv/bin/activate
$ pip install pillow==9.5.0 --no-binary :all:
$ ipython
In [1]: from PIL import _imagingft
ImportError: cannot import name '_imagingft' from 'PIL'

Whoa, what's up with that pip install line?

  1. I'm installing 9.5 to work around this bug.
  2. I'm installing with --no-binary :all: based on advice given in #7949.

Expected Result

_imagingft is successfully imported.

Observed Result

ImportError: cannot import name '_imagingft' from 'PIL'

Please include code that reproduces the issue

Done, above.

Thoughts

I reckon I'm probably missing a dependency, but I don't know what. I've tried installing freetype-devel, libjpeg-turbo-devel, and libraqm-devel to no avail.

aclark4life commented 4 months ago

Have you tried the void linux binary ?

Yay295 commented 4 months ago

ipython may not be using your local venv. Try pip install ipython after activating your environment.

If you're installing from source (which you are, since you used --no-binary :all:), then yes, you need freetype-devel. But that should be the only dependency you need for fonts if void linux is at all reasonable (which I assume it is).

ipython may not be using your local venv. Try pip install ipython after activating your environment.

Good point. @bryankaplan Does running the following produce the same output as your python3 -m PIL --report above?

from PIL import features
features.pilinfo()

@aclark4life That's v10.4, and I need 9.5.

ipython may not be using your local venv. Try pip install ipython after activating your environment.

@Yay295 Yes, it is. This code was extracted from the larger project to demonstrate the problem. But I tried installing ipython in the venv, just to be sure, and indeed the ImportError is identical.

@nulano They're 100% identical. (I diff'd the output.)

Ok, I've managed to reproduce in a Docker container.

You probably tried to install Pillow before installing freetype-devel, which didn't work:

$ docker pull ghcr.io/void-linux/void-glibc-full
$ docker run --rm -it ghcr.io/void-linux/void-glibc-full
# xbps-install -Su
[...]
# xbps-install gcc python3-devel libjpeg-turbo-devel zlib-devel freetype-devel
[...]
# python -m venv venv
# . ./venv/bin/activate
(venv) # pip install pillow==9.5.0 --no-binary :all:
[...]
(venv) # python -c "from PIL import _imagingft; print(_imagingft.freetype2_version)"
ImportError: cannot import name '_imagingft' from 'PIL' (/venv/lib/python3.12/site-packages/PIL/__init__.py)

Even if you then install freetype-devel and try to install Pillow in a new venv, it will use a cached wheel:

(venv) # deactivate
# xbps-install freetype-devel
[...]
# python -m venv venv2
# . ./venv2/bin/activate
(venv2) # pip install pillow==9.5.0 --no-binary :all:
Collecting pillow==9.5.0
  Using cached Pillow-9.5.0-cp312-cp312-linux_x86_64.whl
Installing collected packages: pillow
Successfully installed pillow-9.5.0
(venv2) # python -c "from PIL import _imagingft; print(_imagingft.freetype2_version)"
ImportError: cannot import name '_imagingft' from 'PIL' (/venv/lib/python3.12/site-packages/PIL/__init__.py)

You have to add a parameter to pip to ask it to ignore the cached wheel (--no-cache-dir Pillow), or just remove the wheel from cache with pip cache remove Pillow:

(venv2) # deactivate
# python -m venv venv3
# . ./venv3/bin/activate
(venv3) # pip cache remove Pillow
(venv3) # pip install pillow==9.5.0 --no-binary :all:
[...]
(venv3) # python -c "from PIL import _imagingft; print(_imagingft.freetype2_version)"
2.13.2

Does that help?

@nulano Thank you! I knew as soon as I started reading your thought that it was probably the answer, and I started typing this response before the test was complete. Test succeeded. Thank you so much!
