Pandas-1.3.x fails with PyPy-3.7 and 3.8 on Windows (only?), but not Pandas-1.2.5
If a PyPy user can try the experience as here, on non-pypi Windows, I would be glad to know if it works for him/her.
Failing with Pandas-1.3.X, not with Pandas-1.2.5 (cgohlke wheels)
import seaborn as sns
sns.set()
df = sns.load_dataset("iris")
sns.pairplot(df, hue="species", height=1.5)
