import pandas as pd

/anaconda3/lib/python3.6/site-packages/ipykernel_launcher.py:2: FutureWarning: pandas.scatter_matrix is deprecated. Use pandas.plotting.scatter_matrix instead

対処方法

pd.scatter_matrix ➡︎ pd.plotting.scatter_matrix

import pandas as pd
grr = pd.plotting.scatter_matrix(iris_dataframe, c=y_train, figsize=(15,15), marker="o",hist_kwds={'bins':20}, s=60, alpha=.8, cmap=mglearn.cm3)
