Jupyter laptop import error: no module named "matplotlib"

Question

I am a Ubuntu 16.4 user and I installed anaconda3 and use both the python2 and python3 kernels.

>>> List of jupyter kernel specifications Available kernels: python2 / home / peterkim / .local / share / jupyter / kernels / python2 python3 / home / peterkim / anaconda3 / share / jupyter / kernels / python3

and ... the problem was that I don’t know where / how to install the packages so that in my python2 jupyter laptop there would be no error "module not named ...". I tried pip install matplotliband pip install matplotlib conda install matplotlibI also conda install matplotlib'/ home // anaconda2 / pkgs' in sys.path.

(I also installed anaconda2 in search of a way to use parallel kernels. After I realized that anaconda2 was not needed. But I did not remove it.)

Thanks for helping me in advance!
