2. Getting Started

2.1. Try rootpy on CERN’s LXPLUS

First, set up ROOT:

source /afs/cern.ch/sw/lcg/contrib/gcc/4.3/x86_64-slc5/setup.sh &&\
cd /afs/cern.ch/sw/lcg/app/releases/ROOT/5.34.00/x86_64-slc5-gcc43-opt/root &&\
source bin/thisroot.sh &&\
cd -

Then, create and activate a virtualenv (change my_env at your will):

virtualenv my_env # necessary only the first time
source my_env/bin/activate

Get the latest source:

git clone https://github.com/rootpy/rootpy.git

and install it:

~/my_env/bin/python rootpy/setup.py install

Note that neither sudo nor –user is used, because we are in a virtualenv.

rootpy should now be ready to use:

>>> import rootpy
