Test failures

[heplesser]

@IlaCar Thank you for your report. We need some more information to analyse the situation. Can you please post

• Which operating system you are using
• The configuration report shown at the end of the CMake run
• The test configuration report shown at the beginning of the make installcheck run
• From the make installcheck output the output related to nest-install.share.nest.testsuite.pytests.test_helper_functions.test_dict_is_subset[a0-b0-True] or one of the other tests that failed

[IlaCar]

Of course:

• Ubuntu 20.04.6 LTS
• cmake.png
• installcheck.png
• installcheck_out.txt
  
  
  installcheck_out.txt

@IlaCar Thank you for the additional information! Most of the tests fail because they depend on combining to dictionaries via dict() | dict() which was introduced with Python 3.9 and thus does not work under Python 3.8. The test_weight_recorder_with_bernoulli fails because it depends on the optional strict parameter to numpy.testing.assert_array_equal(), which was introduced in NumPy 1.24.0. Thus, the failing tests do not indicate any problems in NEST as such, they only cause a problem for the testing mechanism.

In view of the significant performance improvements that came with Python 3.10, I would strongly advise to update Python to at least 3.10.

I will close this issue now, but feel free to re-open.

@heplesser : the NEST docs still mention Python 3.8 as the minimum required version; should this be updated?

This needs a deeper discussion which I will initiate. It is a balance concerning resources for testing and supporting older versions while also exploiting the capabilities of cutting-edge tools. Normal support for Ubuntu 20.04 LTS, e.g., will end only in April 2025 and it comes on-board with gcc 9.4, cmake 3.16 and Python 3.8.
