KeyError: column_name

2024/7/7 3:43:38

I am writing a python code, it should read the values of columns but I am getting the KeyError: 'column_name' error. Can anyone please tell me how to fix this issue.

import numpy as np
from sklearn.cluster import KMeans
import pandas as pd### For the purposes of this example, we store feature data from our
### dataframe `df`, in the `f1` and `f2` arrays. We combine this into
### a feature matrix `X` before entering it into the algorithm.df = pd.read_csv(r'C:\Users\Desktop\data.csv')print (df)#df = pd.read_csv(csv_file)"""
saved_column = df.Distance_Feature
saved_column = df.Speeding_Featureprint(saved_column)
"""f1 = df['Distance_Feature'].tolist()
f2 = df['Speeding_Feature'].tolist()print(f1)
print(f2)X=np.matrix(zip(f1,f2))print(X)kmeans = KMeans(n_clusters=2).fit(X)

Can anyone please help me.

Answer

Asumming 'C:\Users\Desktop\data.csv' contains the following data

Distance_Feature Speeding_Feature
1   2
3   4
5   6...

Change

df = pd.read_csv(r'C:\Users\Desktop\data.csv')

to

    df = pd.read_csv("data.txt",names=["Distance_Feature","Speeding_Feature"],sep= "\s+|\t+|\s+\t+|\t+\s+",header=1) # Here it is assumed white space separator, if another separator is used change `sep`.
