iloc giving ‘IndexError: single positional indexer is out-of-bounds’

  • 7

I am trying to encode some information to read into a Machine Learning model using the following 

import numpy as np
import pandas as pd
import matplotlib.pyplot as py

Dataset = pd.read_csv('filename.csv', sep = ',')

X = Dataset.iloc[:,:-1].values
Y = Dataset.iloc[:,18].values

from sklearn.preprocessing import LabelEncoder, OneHotEncoder
labelencoder_X = LabelEncoder()
X[:, 0] = labelencoder_X.fit_transform(X[:, 0])
onehotencoder = OneHotEncoder(categorical_features = [0])
X = onehotencoder.fit_transform(X).toarray()

however I am getting an error that reads

IndexError: single positional indexer is out-of-bounds

      This error is caused by:

      Y = Dataset.iloc[:,18].values

      Indexing is out of bounds here most probably because there are less than 19 columns in your Dataset, so column 18 does not exist. The following code you provided doesn’t use Y at all, so you can just comment out this line for now.
