While I was using seaborn in Python to plot a scatter plot, I encountered this error: TypeError: unhashable type: 'Series'. The function I called was
sd.scatterplot(x='Close',y='Open', data=df)
where 'Close' and 'Open' are the names of columns in the pandas dataframe. Both columns are of float64 type. I've never had this issue before, has something changed? How do I fix this?
