# This is a helper script to install python2 detectors (numenta, htmjava) if possible.
# It is done through creating a python2 virtualenv and installing the packages there.
# Requirements: virtualenv, pytnon2, bash
# If fails, nothing happens, but py2 detectors won't be usable

## Install Python 2 detectors:

# 1/ Numenta detector
pip install -r nab/detectors/numenta/requirements.txt
python nab/detectors/numenta/setup.py install --force 

# 2/ htmjava detector

gradle clean build || exit
cd ${REPO}
pip install -r nab/detectors/htmjava/requirements.txt
python nab/detectors/htmjava/setup.py install --force
