See, when you install any software using pip, it defaults to the path: "/usr/local/lib/python3.5/dist-packages/numpy" for installing that software.

Only the root user has access to this area of control (better security) and so, you'll need to the keyword sudo before such commands to enable that software (in this case, pip) to perform it's operations with a root user access level.

So, your command will now become:

sudo pip3 install numpy
