Histograms in zfit

We can fit histograms directly loaded from a root histogram.

import mplhep
import uproot
import zfit
from skhep_testdata import data_path

filename = data_path("uproot-histograms.root", raise_missing=False)

No module named 'nlopt'

histos = [h.to_hist() for h in uproot.open(filename).values()]

data = zfit.data.BinnedData.from_hist(histos[0])

mplhep.histplot(histos[0])
