Matplotlib import error after installing Seaborn

Question

I have just installed Seaborn in my .local directory of a CentOS 7 machine using: pip install --user seaborn Now when I am trying import matplotlib.pyplot as plt in ipython console I am getting the error:

ImportError: No module named Tkinter

This was not happening earlier, i.e. before the installation (which upgraded matplotlib to the version 2.2.4). I have checked with other users and they are not getting this error, it is importing normally for them. I did matplotlib.use('agg'), but then plt.show() is not showing the GUI. Please suggest what can be done to be able to import matplotlib normally.

I also want to add that I do not have sudo privileges in the said machine.
