Answer 1

First uninstall existing version

pip uninstall pillow

Then try installing

pip install pillow==4.0.0

Answer 2

If you're using Anaconda, try

conda uninstall pillow and then pip install pillow

Came across this issue while working on Caffe2 on Windows 10 (Anaconda 4.5) and this worked for me. Here's the github post on this issue.

Answer 3

I had the same problem with anaconda 5.0.1, using it with caffe on windows 10. i just did

conda install PIL

it worked for me.

Answer 4

Seems like some issue is there with tensorflow 1.12.0 +Python 3.6.0 + win10

Working fine with conda tensorflow.

below steps worked for me for pip tensorflow.

uninstall tensorflow replace your python version with 3.6.1 install latest version of tensorflow(1.13.0)

For installing Tensorflow follow below link:- https://www.tensorflow.org/install/pip

Answer 5

There's a problem in Python itself which means binary wheels build using Python 3.6.1 (like Pillow 4.1.0) won't install on Python 3.6.0.

This has affected a number of Python libraries.

However, there's the new Pillow 4.1.1 release works around this, so you can now update to Pillow 4.1.1 and use it with both Python 3.6.0 and 3.6.1.

Answer 6

As in Sean's answer, I had to uninstall (I'm using Anaconda Python 3.6, BTW) with

conda uninstall pillow

I tried it with PIL, but there was no such package. Uninstalling pillow also meant uninstalling packages that depend on it, in my case "anaconda-navigator" and "scikit-image". After I reinstalled Pillow 4.0.0 with

 conda install pillow=4.0.0

and tested it with

python -c "from PIL import Image"

which, if successful, you don't see an error message, I reinstalled the packages that were uninstalled along with Pillow 4.1.0.

conda install anaconda-navigator
conda install scikit-image
