install a recent version of scikit learn  

You may need to override CMSSW's version of scikit learn in order to evaluate the BDT.
To do so:  

cd CMSSW_X_X_X
cmsenv                                             # this is meant to have CMSSW's python version handy
cd                                                 # go back to your home
python -m pip install --upgrade --user sklearn     # do a local installation of the most recent scikit learn *against the correct python version!!*

Now you only have to import the correct scikit learn module:

• modules are imported ordered as they appear in sys.path
• put the path to your local installation first, that is sys.path.insert(0, os.environ['HOME'] + '/.local/lib/python2.7/site-packages')
