About this question
I have this code, I want to remove the column 'timestamp' from the file: u.data but can't. It shows the error
"ValueError: labels ['timestamp'] not contained in axis"How can I correct it
import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
plt.rc("font", size=14)
from sklearn.linear_model import LinearRegression
from sklearn.linear_model import Ridge
from sklearn.cross_validation import KFold
from sklearn.cross_validation import train_test_split
data = pd.read_table('u.data')
data.columns=['userID', 'itemID','rating', 'timestamp']
data.drop('timestamp', axis=1)
N = len(data)
print data.shape
print list(data.columns)
print data.head(10)
