# xarray.backends.ScipyBackendEntrypoint

### *class* xarray.backends.ScipyBackendEntrypoint[[source]](https://github.com/pydata/xarray/blob/main/xarray/backends/scipy_.py#L402-L489)

Backend for netCDF files based on the scipy package.

It can open “.nc”, “.cdf”, and “nc..gz” files but will only be
selected as the default if the “netcdf4” and “h5netcdf” engines are
not available. It has the advantage that is is a lightweight engine
that has no system requirements (unlike netcdf4 and h5netcdf).

Additionally it can open gzip compressed (“.gz”) files.
