Update Echoshader for newer NumPy and Zarr (GSoC 2026) #218
Description
Currently, zarr and numpy are pinned to older major versions (zarr>=2,<3 and numpy<2). It would be useful to unpin these and test Echoshader’s notebooks, updating the code where necessary to ensure compatibility with newer versions.

Hi @Safwannn89, we ran into an error while installing echoshader on the cloud due to dependency issues!
The problem is related to #221, because that PR pins
zarr==2.16.1. Sorry that’s my fault, I missed that.The best approach now would be to align with echopype current dependencies (i.e.,
zarr>=3and no pinning onnumpy), so that everything remains compatible moving forward.Would you be happy to make that change and check that the notebooks still run? Sorry again, missed that!

Hi @LOCEANlloydizard, no worries at all! It happens. I will get this updated right away. I'll align the dependencies with echopype by setting zarr>=3 and ensuring numpy is completely unpinned. I will run through all the tutorial notebooks locally to verify everything is fully compatible and stable, and then I'll open a new PR with the fix!

Hi @LOCEANlloydizard! I know you have a very busy schedule right now, so absolutely no rush, but I just wanted to gently ping this PR #242 for whenever you have a free moment. I also sent you a quick email last week with a little more context. Let me know if you need me to adjust anything once you get a chance to review it!
Thanks.
