Motivation
saxdepends onxarraybut not its netCDF backend. Several PDKs ship their data as netCDF files, and withoutnetCDF4installed,xarray.open_dataset(...)raises a backend error. In gdsfactory+ this surfaces as a silent failure, making it hard to diagnose.Change
Pull in xarray's
ioextra so the netCDF dependencies are installed withsax:The
ioextra includesnetCDF4,h5netcdf,scipy,zarr,fsspec,cftime, andpooch.
