Boa tarde.
No link https://seaborn.pydata.org/generated/seaborn.distplot.html?highlight=distplot#seaborn.distplot (seaborn.distplot) consta que a função está obsoleta:
Warning
This function is deprecated and will be removed in a future version. Please adapt your code to use one of two new functions:
displot(), a figure-level function with a similar flexibility over the kind of plot to draw
histplot(), an axes-level function for plotting histograms, including with kernel density smoothing
Tem alguma função que substitui?
