use backend= instead of deprecated native_namespace= in nw.from_dict

[MarcoGorelli]

native_namespace in nw.from_dict is deprecated since Narwhals 1.27, which is already your minimum version

hierarchicalforecast/settings.ini

Line 18 in 434c411

requirements = numpy, numba, pandas>=2.1.0, scikit-learn>=1.2, quadprog, clarabel, matplotlib, narwhals>=1.27.0, utilsforecast>=0.2.12, intel-cmplr-lib-rt ; platform_system!="Darwin" and platform_machine=="x86_64"

so is safe to do even for the oldest versions

For future reference, I'd also suggest using narwhals.stable.v1 to guard against API changes https://narwhals-dev.github.io/narwhals/backcompat/

Thanks, makes sense!

Agree wrt stable API, but we need functions that are not in v1, so then it doesn't work, right?

thanks!

yup, true - do you remember which non-v1 functions you need?

(btw, we're close to having v2 🥳 )

I think it was the pivot function. Nice to see v2 coming! I want to start moving the rest of our libs to Narwhals too, but it'll be a big effort.
