What happened?

We've been getting this AttributeError on PyGMT's dev CI which tests nightly packages of numpy/xarray/etc. See https://github.com/GenericMappingTools/pygmt/actions/runs/6043991082/job/16401918043#step:16:40

What did you expect to happen?

Running import xarray as xr should work with numpy 2.0.

Minimal Complete Verifiable Example

```Python mamba create --name xr_with_np2 python=3.11 mamba activate xr_with_np2 python -m pip install --pre --extra-index https://pypi.anaconda.org/scientific-python-nightly-wheels/simple numpy pandas xarray

python -c "import xarray as xr" ```

MVCE confirmation

  • [X] Minimal example — the example is as focused as reasonably possible to demonstrate the underlying issue in xarray.
  • [X] Complete example — the example is self-contained, including all data and the text of any traceback.
  • [X] Verifiable example — the example copy & pastes into an IPython prompt or Binder notebook, returning the result.
  • [X] New issue — a search of GitHub Issues suggests this is not a duplicate.
