What happened?

I am experiencing an error when using the array.interp function. The error message indicates that the function signature does not match with scipy interpn.

It 's linked to scipy update 1.10.0 (2023/01/03).

What did you expect to happen?

I would interpolate 2D data of numpy float64 : two data lattitudes and longitudes following <xarray.DataArray (row: 32, col: 32)>. da is a xarray dataset : <xarray.Dataset> Dimensions: (lat: 721, lon: 1441) Coordinates: * lat (lat) float64 90.0 89.75 89.5 89.25 ... -89.25 -89.5 -89.75 -90.0 * lon (lon) float64 0.0 0.25 0.5 0.75 1.0 ... 359.2 359.5 359.8 360.0 Data variables: hgt (lat, lon) >f4 13.61 13.61 13.61 13.61 ... -29.53 -29.53 -29.53 Attributes:

Minimal Complete Verifiable Example

Python interpolated_da = da.interp( { "x": xr.DataArray(x, dims=("x", "y")), "y": xr.DataArray(y, dims=("x", "y")), } )

MVCE confirmation

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