I am trying to use matplotlib and seaborn to perform some data vizualisation (heatmap here). But i realized that the matplotlib heatmap doesn't look the same at all whether I import seaborn or not.
I've launched a matplotlib heatmap before importing seaborn:
And the same matrix heatmap after importing seaborn:
I therefore have two questions:
- First why is this happening?
- Second is there a way to counter this fact?
