Xarray, NumPy, and NetCDF ABI Compatibility

June 5, 2025

Xarray can write and load netCDF4 files into datasets. Warning messages may appear when using older netCDF4 files with newer versions of Xarray or NumPy like:

RuntimeWarning: numpy.ndarray size changed, may indicate binary incompatibility. Expected 16 from C header, got 96 from PyObject

This may indicate underlying incompatibilities between the versions of Xarray, Pandas, NumPy, and the netCDF4 library.
