Installation Error: in short, Pillow 7.2.0 does not support Python 3.10

Request Help
1

Hi team,

I’m having some installation issues for the command pip install openflexure-microscope-client

Here are the steps I followed:
I have a (nearly fresh) windows 10 install. I’ve installed Spyder IDE for all users.
I then went to python.org and installed the latest python release (python 3.10) for all users and selected the “Add to PATH” option.

Then I opened a command prompt as administrator and ran pip install openflexure-microscope-client

This throws an error. Full output:

Other than installing an old version of python, is there an easy way around this?

It appears the last snippet I posted has this excerpt:

      The headers or library files could not be found for zlib,
      a required dependency when compiling Pillow from source.

      Please see the install instructions at:

So we head over to the link, and land on a page with this matrix:

It appears an upgrade to a newer version of Pillow may be required for the project? Pillow 7.2 only supports python 3.8 or lower. Python 3.8 was upgrdaded due to security reasons, so it would be good practice to make the project compatible with later versions.
:thinking:

4

To make matters slightly more difficult, python.org no longer provides installers for python 3.8 which is the last version that pillow 7.2 supports.

5

That is rather frustrating. Python dependencies are never simple.

6

Yea. I noticed anaconda ships with an older python version. Turns out it’s Python 3.9 so that’s not actually that helpful.

I uninstalled python 3.10 and Spyder.

Installed Anaconda. Anaconda Navigator is suggesting I updated the Spyder IDE… why not. The updater gets stuck with no error messages.

It does appear that python related modules and libraries really are never simple. I’ve been spoiled by apt-get packages and .deb

Ok ok, the solution is simple.

Just download the microscope_client.py from gitlab, don’t bother pip installing it, and away you go. Just works!

I haven’t fully tested all the functions etc, it might still error out on me but I’m able to display images.

Well done for solving your own problem! I see there is already an issue that gives few details, this is really helpful and explains precisely what the problem is. Thanks for linking to it from the issue thread.

I’ve updated the dependencies: could you try installing:

https://gitlab.com/openflexure/openflexure-microscope-pyclient/-/jobs/3186253437/artifacts/raw/dist/openflexure_microscope_client-0.1.7-py3-none-any.whl?inline=false

(I think this should be installable with pip, after you have first installed wheel with pip install wheel)

If you are using a Raspberry Pi I’d be particularly keen to hear whether this works for you! I’ve added tests that should now check it installs OK on Python 3.7 through 3.10, but I don’t currently have CI set up to check if it would install on a Pi. That’s tricky, though not (I think) impossible.

If this all works, I’ll make another release so the changes come through automatically when you try to install with pip.

Thank you Richard! I will try that when I am able and will report back the results.

This will shortly be updated on PyPI, so you can pip install openflexure_microscope_client and get Pillow 9. Thanks for flagging this.
