You really deserve much more likes and views. You explained why we made heatmaps and how to analyze them and make meaningful decision. It was a practical teaching, I love it.

When I write the same, I am getting error instead of heat map. Any idea? Why? f , ax = plt.subplots(figsize = (14,12)) plt.title('Correlation of Numeric Features with Sale Price',y=1,size=16) sns.heatmap(correlation,square = True, vmax=0.8) --------------------------- AttributeError Traceback (most recent call last) in ----> 1 f , ax = plt.subplots(figsize = (14,12)) 2 3 plt.title('Correlation of Numeric Features with Sale Price',y=1,size=16) 4 5 sns.heatmap(correlation,square = True, vmax=0.8) AttributeError: module 'matplotlib' has no attribute 'subplots'
