Windows Nightly build error: pip install of SimpleITK build failing

Development
1

Between Oct 7 and Oct 8, the installation of SimpleITK from its build tree started to fail.

Notes:

  • The commits introduced between these two dates are likely unrelated.
  • The error can NOT be reproduced by locally running cmake.exe -P D:\D\P\S-0-build\SimpleITK_install_step.cmake
    • Running from the windows terminal with current drive being either C: or D: does not allow to reproduce.
    • Removing the SimpleITK-* directories from D:\D\P\S-0-build\python-install\Lib\site-packages does not allow to reproduce.

The associated error (logged into file SimpleITK_install_step_error.txt) is the copied below.

  DEPRECATION: A future pip version will change local packages to be built in-place without first copying to a temporary directory. We recommend you use --use-feature=in-tree-build to test your packages with this new behavior before it becomes the default.
   pip 21.3 will remove support for this functionality. You can find discussion regarding this at https://github.com/pypa/pip/issues/7555.

The SimpleITK issue occurred on some earlier dates as well.
CDash 2022-09-30
CDash 2022-10-03

COMP: Update ITK to post-v5.3rc04 version and SimpleITK to post-v2.2.0 · Slicer/Slicer@4d1c98e · GitHub did include a change to use pip to install SimpleITK rather than using setup.py which was based on corresponding change at Use pip to install SimpleITK · SimpleITK/SimpleITK@3ce91db · GitHub. That would be my best suspicion about why it would’ve started to randomly occur.

This has been happening intermittently for a while, I thought I had sorted it out earlier when I fixed the nightly build not being cleaned correctly.

To follow up, the issue has been identified and can be reproduced. Thanks @jamesobutler and @Sam_Horvath for your comments :pray:

Since the SimpleITK external project depends on:

  • ITK
  • Swig
  • python-setuptools (itself depending on python-ensurepip and python)
  • python

reproducing the issue required to:

  • delete the content of D:\D\P\S-0-build\python-install
  • open the Slicer.sln and right-click build only onto the python, python-ensurepip and python-setuptools projects
  • re-run the command cmake.exe -P D:\D\P\S-0-build\SimpleITK_install_step.cmake

Then, the warning mentioning pip 21.3 is reported and the error is reproduced.

To address the issue, we need to add python-pip as a dependency to the SimpleITK project.

The regression should be fixed by https://github.com/Slicer/Slicer/pull/6576

The plan is to integrate the pull request by 10pm ET so that the upcoming round of nightly is completed with the fix.

Good catch! Thanks and sorry I didn’t catch that earlier.
