Face Recognition Python script. Working on the jetson nano and also on windows using a USB camera.
##setup: jetson nano: sudo sh archiconda.sh -b -p /opt/archiconda3 now runnig conda3 install sudo /opt/archiconda3/bin/conda install scikit-learn
##then conda create -n [Virtualenv_Name] python=3.7 scikit-learn source activate py3k then install opencv through the sh script sudo sh install_opencv4.0.0_Nano.sh
##wait ... it takes over an hour on the nano after this you will have scikit-learn installed on the virtual environment and also opencv 4.0.0
##remember to move cv2.so to cv2.so cd /usr/local/python/cv2/python-3.6
##mv cv2.cpython-36m-aarch64-linux-gnu.so cv2.so
##after this conda will be located here: /opt/archiconda3/bin/conda
##check it out with: /opt/archiconda3/bin/conda --version
##Conda allows you to create separate environments containing files, packages and their dependencies that will not interact with other environments. So I created a py37 environment with scikit-learn
##windows: on windows what worked was py -m pip install opencv py -m pip install scikit-learn
