Seaborn pairplot is closing immediately

Question

I want to plot a pairplot using seaborn. This is the code:

from matplotlib import pyplot

import seaborn as sns

import pandas as pd

df = pd.read_csv("datasets/iris.csv", index_col=0).drop("species", axis=1);

print(df.head())
res = sns.pairplot(data=df, kind="scatter")
pyplot.show()

But it is shown for few milliseconds and then it closes. How to fix this?
