requirements.txt

jupyter==1.0.0
seaborn==0.9.0
plotly==3.6.1

It gives me an error when i try to plot it as Pairplot

Code:

df= pd.read_csv('https://gist.github.com/ktisha/c21e73a1bd1700294ef790c56c8aec1f')    
df.rename(columns={'Class variable (0 or 1)':'Target'}, inplace=True)
sns.pairplot(df,hue='Target')

Error:

LinAlgError: singular matrix

The same code works on google collab and on anaconda base environment but not on any other virtual env. Also, the code works if I install seaborn=0.7.1

WHY is this happening? Please someone help me resolve this issue!

Thank You.

conda list -e > requirements.txt gives me this:

Answer 1

I cannot reproduce the error. There is a different one though, which is due to the link not working correctly. The following works correctly for me.

import matplotlib.pyplot as plt
import pandas as pd
import seaborn as sns

n = "https://gist.githubusercontent.com/ktisha/c21e73a1bd1700294ef790c56c8aec1f/raw/819b69b5736821ccee93d05b51de0510bea00294/pima-indians-diabetes.csv"
df= pd.read_csv(n, comment='#', header=None, sep=",")    
df.columns=list("ABCDEFGHI")

print(df.head())
sns.pairplot(df, hue='I', vars=df.columns[:-1])
plt.show()

Answer 2

使用 PairGrid 而不是 fairplot g = sns.PairGrid(df , hue = 'TARGET CLASS') g = g.map(sns.scatterplot)
