  <p>And this the code I'm using</p>
  
  <pre><code>    import pytesseract
      varnum= pytesseract.image_to_string(Image.open('images/table/img.jpg'))
      varnum = float(varnum)
      print varnum    
  </code></pre>
  
  <p>Thanks!!!!</p>
  
  <p>With this code I'm able to read all numbers</p>
  
  <pre><code>import pytesseract
  
  
  start_time = time.clock()
  y = pytesseract.image_to_string(Image.open('images/table/1.jpg'),config='-psm 10000')
  x = pytesseract.image_to_string(Image.open('images/table/1.jpg'),config='-psm 10000')
  
  print y
  print x
  
  y = pytesseract.image_to_string(Image.open('images/table/68.5.jpg'),config='-psm 10000')
  x = pytesseract.image_to_string(Image.open('images/table/68.5.jpg'),config='-psm 10000')
  
  print y
  print x
  
  print time.clock() - start_time, "seconds" 
  </code></pre>
  
  <p>result</p>
