Jupyter unable to use Vartests that’s found in my site-packages

I have Anaconda installed in my system. I have used Jupyter notebook to install vartests package using “!pip install vartests”. In my site-packages folder inside Anaconda/lib, I am able to find a directory for vartests, which means the package has been installed. But when I try to import it in the same jupyter notebook, it says import error. I’ve tried using “!{sys.executable} -m pip install vartests” but it doesn’t help. I’ve followed things written in “Installing Python Packages from Jupyter Notebook” by Jake VanderPlas as well. One thing, my “!type -a python” doesn’t give me anything. Is there a way out from this?
