Heppy only depends on python and ROOT (if you intend to read events from a ROOT file), making the installation fairly simple. If you're using heppy in the context of the CMS or FCC software on SLC6, you're all set and you can proceed to the next section
python 2.x, x>5
On top of python, you need the following python packages:
numpy
ipython (not strictly needed, but really useful)
To get them, install pip and use it to install these packages.
ROOT 5, with pyroot support (optional)
Note that you need to ensure that ROOT was compiled with the same version of python as the one in your PATH.
To check that, do the following:
python
import ROOT
Any error message needs to be taken care of before going further.
First fork the heppy repository on your github account.
Then, clone your copy of the heppy repository locally.
Move to the heppy directory run the initialization script (to be done everytime you want to use heppy):
source ./init.sh
Check that you can now import heppy:
python
import heppy
