numpy2 support

[joamatab]

What's the plan for numpy2 support?

[yaugenst-flex]

For the most part this is gated by numpy2 support from dependencies, the tidy3d frontend is already numpy2 compatible as far as I can tell (minus two np.trapz calls...). Are there any numpy2-specific features that you need?

Hi Joaquin! Hope you're well.

So if the issue is a packaging/integration one with other packages that require/use 2.0, I'm opening a PR that will loosen the current pyproject.toml requirement. My understanding is the same as Yannick that we already are 2.0 compatible mostly limited by the dependencies on this.

tidy3d/pyproject.toml

Line 31 in 53ef995

numpy = "<2"

Then just need to make sure tests pass and we'd release it in pypi the next release, either 2.7.3 or 2.8.0 in the next few weeks I believe. If there's anything feature-specific we can also look into that as Yannick mentions.

I know there was an autograd issue but it seems like they have merged their numpy v2 PR. But yeah we just need to test everything.

Note that we would need some logic to call np.trapz or np.trapezoid depending on numpy version.

Hi there, thanks for the cross-link. We released a new version of Autograd: https://github.com/HIPS/autograd/releases/tag/v1.7.0, which includes NumPy v2 support through the above PR. It will be available via PyPI later in the day.

Hey all,
any other roadblocks, that would need to be addressed?

Hey @jan-david-fischbach, this is tracked in #1913 and will (probably?) make it into the next release. However I think current develop should already be fine with numpy 2 (there was only a np.trapz call that was replaced), so if you are willing to install from develop and force upgrade numpy afterward it might just work? No guarantees though 😬
