in ML course (2017)
lesson 3 - in rf_interpretation
i tried plotting hierarchical clustering without feature importance (finding the most effective independent features)
i mean instead of just keeping the 30 important columns (first image)
i used all columns (second image)
then i got this error “Distance matrix ‘X’ must be symmetric”
why is that ?
i’m not sure , but i think that error raised because of one or several columns has some problems
or because the number of columns are too many
could you please answer this question?
