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)

[Charango-Chile]

The offending line is on the file plotting.py:

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

This style does no longer exists within matplotlib. Changing the line to another style ("classic" for example) removes the error and in your code you can then use plt.style.use() with your own desired available style.

I've to change that in the plotting.py, can't we update the plotting.py file ( im using venv so I can locally update that and run it perfectly but for someone who just downloaded it won't be good so expecting the changes )
