ImportError: cannot import name '_imaging' #4982

AndreasLuckert · 2020-10-15T11:30:56Z

What did you do?

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

Hi. Could you provide some detail on how you installed Pillow?

AndreasLuckert · 2020-10-15T11:56:23Z

I installed it with linuxbrew and pip.
If you need any specific output, please let me know.

radarhere · 2020-10-15T12:19:16Z

Knowing the specific commands that you've run could be helpful, and the output of those commands as well ideally.

Two ideas

Could you check that if you uninstall Pillow, and then try to import PIL, that it fails with ModuleNotFoundError? This assures us that you don't have both PIL (before our fork) and Pillow installed simultaneously, or something odd like that.
Could you try upgrading pip and then re-installing Pillow?

AndreasLuckert · 2020-10-15T17:29:15Z

I played around a bit to find out more about the issue.

First, I started python in a standard UNIX-terminal.

andylu@andylu-ThinkPad-Edge-E130:~$ python
Python 3.8.5 (default, Jul 22 2020, 18:54:26) 
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.

Next, I confirmed that it is still that counterintuitive that the "pillow" package needs to imported with "import PIL" in python.

>>> import pil
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'pil'
>>> import pillow
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'pillow'

>>> import PIL
# Astoundingly, the Image script will be imported without the failure which gave rise to this thread initially.
>>> from PIL import Image
>>> Image
<module 'PIL.Image' from '/home/linuxbrew/.linuxbrew/lib/python3.8/site-packages/PIL/Image.py'>
>>> quit()

So why is that?
First, let's uninstall pillow as required.

andylu@andylu-ThinkPad-Edge-E130:~$ pip uninstall PIL

Next, I'm going to upgrade pip, as required

andylu@andylu-ThinkPad-Edge-E130:~$ pip install --upgrade pip
Requirement already up-to-date: pip in /home/linuxbrew/.linuxbrew/lib/python3.8/site-packages (20.2.3)

Then, I'm reinstalling the pillow package:

Now, testing again the intially failed command, which will unfortunately fail again for the same reason:

    from . import _imaging as core

Yet and again, it's possible to import the PIL package and its Image-script flawlessly in a standard python environment

>>> import PIL
>>> from PIL import Image
>>> quit()

Checking again where the pillow packages are installed.
It shows that they have only been installed where they were supposed to be,
i.e. in the linuxbrew site-packages.
NOTE: the python2.7 - directory should not matter in all of these cases

andylu@andylu-ThinkPad-Edge-E130:~$ sudo find / -type d -path "*/PIL*"
[sudo] password for andylu:

/home/linuxbrew/.linuxbrew/lib/python3.8/site-packages/Pillow.libs

By and large, the same question remains as I initially posed:
where does the error ImportError: cannot import name '_imaging' come from in this specific context
when at the same time it doesn't occur in a standard console python3 - environment?

radarhere · 2020-10-16T03:43:03Z

I think the fact that console python3 can import it successfully indicates that the problem isn't with your Pillow installation as such - I think img2pdf hasn't correctly packaged Pillow into /usr/bin/img2pdf

AndreasLuckert · 2020-10-16T07:23:07Z

Yes, this could be true. Thanks for your help.

josch · 2020-10-16T08:45:31Z

Hi, img2pdf author here. I'm not saying that this is a PIL bug but @AndreasLuckert just opened an issue against img2pdf and I do not see how this can possibly be a bug in img2pdf. Given this backtrace:

Traceback (most recent call last):
  File "/usr/bin/img2pdf", line 11, in <module>
    load_entry_point('img2pdf==0.2.3', 'console_scripts', 'img2pdf')()

    from . import _imaging as core
ImportError: cannot import name '_imaging'

All that img2pdf does is to do a from PIL import Image -- what is wrong about that statement? How should img2pdf fix this?

To me this looks more like a wrong installation of PIL, no?

josch · 2020-10-16T10:11:27Z

I strongly suspect that there is something wrong with your setup. I created a ubuntu 18.04 chroot using sudo debootstrap bionic ubuntu-bionic and added the universe repository to the apt sources. Installing img2pdf using pip will not work because qpdf in ubuntu 18.04 is too old for pikepdf. Instead, I can simply run: apt install img2pdf and everything will be fine.

To test installation via pip I created a chroot of ubuntu 20.04 using debootstrap and then ran pip3 install img2pdf:

And then tried converting some images:

$ echo $?
0

And out.pdf looks fine as well. So everything works on a fresh installation. So most likely something is wrong with your setup.

radarhere · 2020-10-16T10:32:30Z

Hi. Ok, @AndreasLuckert, could you try these commands.

python -c "from PIL import Image" - if this fails, then there is a problem with your Pillow installation.
python -c "import img2pdf" - if this fails, then the problem lies between the Pillow and the img2pdf installations.

If both of those pass, but /usr/bin/img2pdf fails, then that's how I came to my idea that something has gone wrong in packaging /usr/bin/img2pdf. I had presumed that /usr/bin/img2pdf was created by the img2pdf installation - but having tried to install img2pdf myself, it's not present, so you created it some other way, right?

The output from python -c "import sys;print(sys.path)" may also help.

josch · 2020-10-16T10:45:16Z

There are two ways to install img2pdf on ubuntu 18.04. Since @AndreasLuckert has /usr/bin/img2pdf it seems they installed it using apt install and not via pip, because pip installs it into /usr/local/bin/img2pdf.

As I showed above, both methods of installing img2pdf (via apt and via pip) work just fine on a fresh Ubuntu installation. So what we are now actually trying to figure out here is what is wrong in the setup of @AndreasLuckert and not what is wrong in either img2pdf or PIL.

AndreasLuckert · 2020-10-16T11:06:35Z

I tried to execute both commands and they worked successfully:

andylu@andylu-ThinkPad-Edge-E130:~$ python -c "from PIL import Image"
andylu@andylu-ThinkPad-Edge-E130:~$ python -c "import img2pdf"

The command revealing the system paths you suggested has the following output:

andylu@andylu-ThinkPad-Edge-E130:~$ python -c "import sys;print(sys.path)"
['', '/home/linuxbrew/.linuxbrew/lib/python3.8/site-packages', '/home/andylu/Dokumente/Allgemeines_material/Sonstiges/Programming/Python/Scripts', '/usr/lib/python3/dist-packages', '/home/andylu', '/home/linuxbrew/.linuxbrew/Cellar/python@3.8/3.8.5/lib/python38.zip', '/home/linuxbrew/.linuxbrew/Cellar/python@3.8/3.8.5/lib/python3.8', '/home/linuxbrew/.linuxbrew/Cellar/python@3.8/3.8.5/lib/python3.8/lib-dynload', '/home/andylu/.local/lib/python3.8/site-packages', '/home/linuxbrew/.linuxbrew/Cellar/python@3.8/3.8.5/lib/python3.8/site-packages', '/home/linuxbrew/.linuxbrew/Cellar/python@3.8/3.8.5/lib/python3.8/site-packages/geos']

Next, checking where img2pdf has been installed:

andylu@andylu-ThinkPad-Edge-E130:~$ which img2pdf
/usr/bin/img2pdf

Check also whether it can be installed via pip:

andylu@andylu-ThinkPad-Edge-E130:~$ pip install img2pdf
Requirement already satisfied: img2pdf in /usr/lib/python3/dist-packages (0.2.3)

Finally, print out all files and directories related to img2pdf on the system:

andylu@andylu-ThinkPad-Edge-E130:~$ sudo find / -iname "*img2pdf*"
[sudo] password for andylu:

I hope this helps in further diagnosis.

josch · 2020-10-16T11:18:25Z

You installed img2pdf via apt (as proven by it being located in /usr/bin/img2pdf and by your output of pip install img2pdf) and you are mixing it with a lot of python libraries that were not installed by apt (as proven by your output of sys.path). You are thus essentially circumventing the dependency system of apt. I'm not surprised that it doesn't work. Trying running img2pdf without all the extra bits from your $HOME.

hugovk · 2020-10-16T11:21:36Z

A general tip: use python -m pip install instead of pip install to avoid env problems: https://snarky.ca/why-you-should-use-python-m-pip/

A virtualenv (or similar) may also help isolate things.

AndreasLuckert · 2020-10-16T12:13:27Z

So should I uninstall img2pdf via apt, then install it via python -m pip install img2pdf?

AndreasLuckert · 2020-10-16T12:34:18Z

Finally everything works like a charm!
Thanks a lot for your time and tips.

The problem was the installation with apt instead of python -m pip.
Now all packages involved are installed in the same place in my linuxbrew directory via pip.

I uninstalled img2pdf via apt with sudo apt purge img2pdf, then installed it again via python -m pip install img2pdf.

Now, the location is correct:

andylu@andylu-ThinkPad-Edge-E130:~$ which img2pdf
