Support Python 3.12

[alecandido]

Unfortunately work-in-progress

[alecandido]

Unfortunately, there is an almost circular dependency with qibo: it is qibojit that depends on qibo, that's why I'm trying to upgrade qibo first.
However, qibo depends on qibojit for the tests, that's why I mistakenly started from here (i.e. I tried first with qibo and it complained about qibojit, but I didn't investigate enough about why...)

[natestemen]

We're trying to support python 3.12 over on mitiq which has recently added Qibo as a dependency. I took a shot at supporting python 3.12 in Qibo and ran into the circular dependency issue as well. I'm not familiar enough with the project infrastructure to fully understand why, but let me know if there are any smaller things I can look into to help move this along!

[alecandido]

Sorry: I just interrupted because of other priorities. I thought no one needed py3.12 yet.

I believe I could make it by today (if not before). It's non-trivial, but still relatively simple.

@BrunoLiegiBastonLiegi @renatomello: apparently, there are issues linting the quantum_info module (here and not in Qibo...)
https://github.com/qiboteam/qibojit/actions/runs/8241315355/job/22538457740#step:10:1785
(among the others, of course they are not related to those purely coming from the Numba/CuPy backends)

weird, may be some problem with the lock?

The lock has no problem on its own, but you could inspect the locked Numba version.

qibojit/poetry.lock

Lines 486 to 491 in 8cfaea4

	[[package]]
	name = "numba"
	version = "0.59.0"
	description = "compiling Python code using LLVM"
	optional = false

Just waiting for qiboteam/qibo#1231 to be merged

[alecandido]

@BrunoLiegiBastonLiegi @renatomello now that qiboteam/qibo#1231 has been merged, we should be ready to merge this as well

[BrunoLiegiBastonLiegi]

Thanks @alecandido, I am probably not the most indicated person to look into this, but to me this is ready. Just a note on the numba and pylint version, the earliest version we support is changing because python-3.12 does not support older versions?

Exactly :)

(Though it is better said the other way round: older versions are not supporting py3.12, because of the dependency arrow)

[alecandido]

Thanks! @stavros11 @BrunoLiegiBastonLiegi

[alecandido]

@natestemen now both Qibo and Qibojit are supporting py3.12 in main. Almost for sure, we'll get another release in less than one month.
