title: ValueError: Input contains infinity or a value too large for dtype('float64')
body: <p>i need help
  I'm working on machine learning.
  I tried to import a dataset using this code:</p>
  
  <pre><code>    # Importing the libraries
      import numpy as np
      import matplotlib.pyplot as plt
      import pandas as pd
  
      # Importing the dataset
      dataset = pd.read_csv('Rural3.csv', low_memory=False)
      X = dataset.iloc[:, :-1].values
      y = dataset.iloc[:, 77].values
  
      # Splitting the dataset into the Training set and Test set
      from sklearn.model_selection import train_test_split
      X_train, X_test, y_train, y_test = train_test_split(X, y, test_size = 0.25, random_state = 0)
  
      # Feature Scaling
      from sklearn.preprocessing import StandardScaler
      sc = StandardScaler()
      X_train = sc.fit_transform(X_train)
      X_test = sc.transform(X_test)
  </code></pre>
  
  <p>However, an error appears: 
  ValueError: Input contains infinity or a value too large for dtype('float64')</p>
  
  <p>What should i do please ? i'm newbie in python.
  Thanks in advance.</p>
