Describe the bug whenever I have "from pypfopt import plotting" in my code it throws an error - see below

Code sample from pypfopt import plotting

Operating system, python version, PyPortfolioOpt version Windows 10, Python 3.11, not sure how to know what PyPortfolioOpt version

Additional context

>>> 
from pypfopt import plotting

@wayner9 please see this ticket: https://github.com/robertmartin8/PyPortfolioOpt/issues/562

@wayner9 please see this ticket: #562

Thanks, but has this been fixed in the latest version? It appears that the most recent update was done in May of this year, I just started using PyPortfolioOpt in October, and I installed using Pip in the last month or so, so presumably I am using the latest version.

Does this mean that on whatever computer or VENV I use for PyPortfolioOpt that I have to go into this file and change the seaborn-dep reference?
