'GrouperView' object has no attribute 'join'

[rootsmusic]

My environment has installed seaborn 0.11.2 (preferred version). I'm running the simple script below.

import seaborn as sns
import pandas as pd
import numpy as np

# Creating a sample DataFrame
data = {
    'A': np.random.randn(100),
    'B': np.random.randn(100),
    'C': np.random.randn(100),
    'D': np.random.randn(100)
}
df = pd.DataFrame(data)

# Create a pair plot
sns.pairplot(df)

Why does the last line output the error: AttributeError: 'GrouperView' object has no attribute 'join'?

I'm not sure what you mean by "preferred version" but 0.11.2 was released more than two years ago and there have been two major release cycles since. I cannot replicate your issue with the latest version (0.13.0). If for some reason you are unable to upgrade your seaborn, you may need to downgrade seaborn dependencies to contemporary versions.
