Support for numpy 2.0 and Python 3.13

Addressing a Problem?

Hello

Is xclim 0.53.2 supporting :

• numpy 2.0 ? 2.1 ? 2.2 ?
• Python 3.13 ?

If not, when do you think xclim will support Python3.13 and at least numpy 2.0 ?
Sorry, maybe I should have opened 2 issues, one for numpy 2 and another for Python 3.13.
Regards

Potential Solution

Support for numpy 2 and Python 3.13 (if not already supported)

Hi @thebaptiste, thanks for the question.

xclim has an open pin for numpy (and we have also recently adopted the Scientific Python SPEC-0 calendar), so we're progressively catching up, possibly dropping support for Python3.10 in the next few months (after we can support Python3.13).

We use numba in order to provide some pre-compilations for some complex algorithms, and unfortunately, it does not (yet) support Python3.13 or numpy>=2.1. As far as I can tell, that's the last dependency we need to be able to support those versions. From their next milestone, I get the impression that the next big release should happen soon, though!

Yes, numba 0.61.0rc1 supports Python 3.13 and numpy 2.1 (see the changelog)
But of course it's better to wait for numba 0.61.0
