Describe the bug I am getting an error with the plotting package:

OSError: 'seaborn-deep' is not a valid package style, path of style file, URL of style file, or library style name (library styles are listed in style.available)

error caused by site-packages\pypfopt\plotting.py", line 21, in

plt.style.use("seaborn-deep")

I am using the latest version of seaborn 0.13.2

Expected behavior

Not to get an error
