ImportError: cannot import name '_imaging' #87

What did you do?

NOTE: I've already asked this question at the pillow-package GibHub-page to find out that the issue must lie in the img2pdf - installation:
https://github.com/python-pillow/Pillow/issues/4982

I converted a PNG to a jp2-file via convert sample.png -quality 0 sample.jp2.
Next, I wanted to convert the resulting jp2-file to a proper PDF:
img2pdf -o sample.pdf sample.jp2

What did you expect to happen?

The jp2-image should have been converted to a PDF via the command img2pdf -o sample.pdf sample.jp2.

What actually happened?

The following error occurred:

User$ img2pdf -o sample.pdf sample.jp2
Traceback (most recent call last):

I've already asked this question at the pillow-package GibHub-page to find out that the issue must lie in the img2pdf - installation

I see no such evidence in the issue you opened with Pillow. Can you clearly quote the part that proves that this is an issue with img2pdf?

All that img2pdf does here is to run from PIL import Image. There is nothing wrong with that statement -- how should your problem be fixed by img2pdf?

Thanks for your quick reply.
The question is then why it's possible to import the PIL package and its Image-script flawlessly in a standard python environment?

There can be many reasons. For example I notice that your python libraries are in /home/linuxbrew/.linuxbrew/. I suspect that you are mixing your environments in an incompatible manner. I suggest you try running img2pdf without linuxbrew in your PYTHONPATH.

The problem was resolved, the details can be found under the following link:

Thanks josch for your time and help.
