Python 3.12 support tracking

[matthewfeickert]

At the moment all of pyhf's base depenendies support Python 3.12 🎉

pyhf/pyproject.toml

Lines 46 to 55 in 6a347f4

	dependencies = [
	"click>=8.0.0", # for console scripts
	"importlib_resources>=1.4.0; python_version < '3.9'", # for resources in schema
	"jsonpatch>=1.15",
	"jsonschema>=4.15.0", # for utils
	"pyyaml>=5.1", # for parsing CLI equal-delimited options
	"scipy>=1.5.1", # requires numpy, which is required by pyhf and tensorflow
	"tqdm>=4.56.0", # for readxml
	"numpy", # compatible versions controlled through scipy
	]

and JAX supports Python 3.12 as of jaxlib v0.4.17

pyhf/pyproject.toml

Lines 76 to 79 in 6a347f4

	jax = [
	"jax>=0.4.1", # c.f. PR #2079
	"jaxlib>=0.4.1", # c.f. PR #2079
	]

. However, both torch and tensorflow do not have releases with Python 3.12 wheels out as of 2023-10-27.

Though now that we have PR #2340 in, we can start bringing in the backends as they support the releases.

Interestingly enough, apparently scrapbook

pyhf/pyproject.toml

Lines 90 to 107 in 6a347f4

	test = [
	"pyhf[all]",
	"scikit-hep-testdata>=0.4.11",
	"pytest>=6.0",
	"coverage[toml]>=6.0.0",
	"pytest-mock",
	"requests-mock>=1.9.0",

	]

requires pyarrow and pyarrow v13.0.0 doesn't support Python 3.12 yet either.

Also iminuit doesn't have Python 3.12 support yet either as of iminuit v2.24.0, though that makes sense as it requires numba for testing and numba needs to do a huge amount of work for each CPython release (c.f. numba/numba#9197).

pyhf/pyproject.toml

Line 81 in 6a347f4

minuit = ["iminuit>=2.7.0"] # c.f. PR #1895

Issues to get fixed before Python 3.12 support can be added:

• In Python 3.12 xml.etree.ElementTree will raise DeprecationWarning: Testing an element's truth value will raise an exception in future versions #2453
• In Python 3.12 tarfile raises DeprecationWarning: Python 3.14 will, by default, filter extracted tar archives and reject files or modify their metadata. #2454
