PyHEP 2020 pyhf Tutorial¶
Welcome!¶
Welcome to the pyhf tutorial given at PyHEP 2020!
We’ll first point you towards our documentation website (scikit-hep.org/pyhf/) and recommend that you visit it for much more detailed explanations and examples.
We don’t have a lot of time today, so let’s dive right in.
We won’t review the full pedagogy of HistFactory, so instead we’ll point you to
the pyhf talk at SciPy 2020.
Instead, let’s move to looking at the pyhf API right away.
Installation¶
If you haven’t already, make a new Python virtual environment and then install pyhf from either PyPI with pip
(pyhf-tutorial) $ python -m pip install pyhf
or Conda-forge
(pyhf-tutorial) $ conda config --add channels conda-forge
(pyhf-tutorial) $ conda install pyhf
Installation Extras¶
If you’re installing from PyPI, you can also install with some of the “extras” that will be useful for doing typical HEP analysis workflows with pyhf. For example, the ‘xmlio’ extra
(pyhf-tutorial) $ python -m pip install pyhf[xmlio]
additionally installs uproot to read ROOT files.
Dependencies for this tutorial¶
To get all the dependencies needed for this tutorial you can just install from the included requirements.txt in the top level binder/ directory of the source repository
(pyhf-tutorial) $ python -m pip install -r binder/requirements.txt
