Note that the error ImportError: cannot import name 'ImageQt' from 'PIL.ImageQt' can be quite misleading.

If you look at the ImageQt.py source code, you'll see that the ImageQt class is only defined if it successfully detects one of the Qt libraries (pyside2/6, PyQt5/6).

So you can get this error if you have a broken install of Qt. You may want to reinstall PySide6 or whatever you've been using.

You could also use a tool like strace and spy on the Python process (if you're using Linux) to see exactly what it's looking for.

strace python -c 'from PIL.ImageQt import ImageQt'

I used this technique to track down why this import was failing under Docker but working properly on a regular desktop.

For the (Ubuntu) Docker container to properly support the import statement, I had to also install these missing libraries:

apt install -y libegl1 libgl1 libxkbcommon0

The problem with the example is that it is attempting to convert a QImage to a QPixmap by passing it directly to the QPixmap constructor, which isn't supported.

Instead, you need to do this:

im = Image.open('test.gif')
image = ImageQt(im)
pixmap = QtGui.QPixmap.fromImage(image)

I had the same error. Here was my workflow. I first installed PIL (not Pillow) using

pip install --no-index -f https://dist.plone.org/thirdparty/ -U PIL

Then I found Pillow and installed it using

pip install Pillow

What fixed my issues was uninstalling both and reinstalling Pillow

pip uninstall PIL
pip uninstall Pillow
pip install Pillow

In your PIL image the last band is the alpha channel, whereas in the Qt image the alpha channel is the first (RGBA vs. ARGB). There may be other ways of permuting the bands but the easiest way seems to use the ImageQt class.

from PIL.ImageQt import ImageQt
qim = ImageQt(im)
pix = QtGui.QPixmap.fromImage(qim)

The latest version of Pillow ImageQT (10.3.0) works best with PyQt6.

In cmd, run the following:

Anaconda3\Scripts>python -m pip install PyQt6

Now Anaconda launches. Quite frankly this is something Anaconda should have updated automatically when you run the update commands shown in the link below. Instead, it only installs PyQt5 which gives the error you have mentioned. There may be some other workaround, but this is the simplest solution I could find.

https://docs.anaconda.com/free/anaconda/install/update-version/

conda update -n base conda

conda update -n base anaconda

I imagine that you're using the latest Pillow version, which at the moment is 10.4.0.

PyQt5 support was removed in Pillow 10.0.0. See https://pillow.readthedocs.io/en/stable/deprecations.html#pyqt5-and-pyside2.

I suggest you switch to PyQt6.
