python 3.x - Python3: Module not found - Stack Overflow
Pip is just a module like any other. It has to be installed for every Python version (2.x, 3.x) but also for special python installations, like anaconda etc.. Since you have installed python once natively and once via anaconda, you also need the module "numpy" in both installations. If my answer helped you, you can mark it as accepted. – g3n35i5.
