Proposed Changes
Xarray-spatial tests were failing due to datashader calling
numpy.warnings
, which is removed in numpy >=1.24.0 ( #779 ). Datashader 0.15.0 removes calls tonumpy.warnings
(pr: holoviz/datashader#1176 , changelog: https://github.com/holoviz/datashader/releases/tag/v0.15.0). This pull requests removes the numpy <= 1.23.4 pin in favour of a datashader >= 1.15.0 pin.Datashader requires Python >=3.8, so this also drops support for Python 3.7.
