python - SciPy Stack installation confusion between Python2 and Python3 -


i have installed scipy stack using pip. however, installed python 2.7, , unable import numpy program in python 3.6 idle.

now installing using pip3, should install stack python 3.6. how uninstall or delete stack python 2.7?

from documentation:

pip uninstall [options] <package> ... pip uninstall [options] -r <requirements file> ...
