Using pip or pip3 to install packages in Anaconda, Python, Jupyter

I have always been under the belief that pip manages packages for one's python2, and pip3 for one's python 3. On a JupyterHub server that I run, I have the habit of installing packages that our team uses as root. Doing sudo -i and then pip3 install <package-name>. Sometimes, this makes import <package-name> work from a python3 notebook in Jupyter. But often not. Then, if I instead do pip install , the package is accessible from notebooks (python3 ones, all of them) on the server. Why is this?

This is what I have:

~# which python 
/anaconda3/bin/python

~# which python3 
/anaconda3/bin/python3

~# which pip 
/anaconda3/bin/pip

~# which pip3 
/anaconda3/bin/pip3

~# which jupyter 
/anaconda3/bin/jupyter

I found the answer to my question here:

pip3 always operates on the Python3 environment only, as pip2 does with Python2. pip operates on whichever environment is appropriate to the context. For example if you are in a Python3 venv, pip will operate on the Python3 environment.
