title: No module named pytesseract error
body: <p>I am trying to use pytesseract for OCR, on a raspberry pi using Raspbian</p>
  
  <p>I have read several questions on this topic, but can't find an answer that works, they usually say to install pytesseract with pip, and I did it.</p>
  
  <p>my code is very simple:</p>
  
  <pre><code>import pytesseract
  from PIL import Image
  print(pytesseract.image_to_string(Image.open('test.jpg')))
  </code></pre>
  
  <p>But it returns error message : <em>"ImportError: No module named 'pytesseract'</em> .</p>
  
  <p>I have installed tesseracrt-ocr (the <strong>whereis tesseract-ocr</strong> command returns  <em>/usr/share/tesseract-ocr</em>)</p>
  
  <p>I have installed pytesseract with <strong>pip install tesseract</strong> (which returns <em>successfully installed Pillow-4.3.0 olefile-0.44 pytesseract-0.1.7</em> ... but the <strong>whereis pytesseract</strong> command does not return anything --> a problem?).</p>
  
  <p>Do you have any idea of the problem I have ?</p>
