You may need to override CMSSW's version of scikit learn in order to evaluate the BDT.
To do so:
cd CMSSW_8_0_25
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')
