title: How to fix a python issue about PiCamera Module with a Raspberry Pi?
body: <p>For my school project, I have to detect a Rubik's Cube and its 6 surfaces thanks to a picamera. I've decided to do it with OpenCv and a python script.
  Here is my code:</p>
  
  <pre><code>import cv2
  from picamera.array import PiRGBArray
  from picamera import PiCamera
  
  camera=PiCamera()
  rawCapture=PiRGBArray(camera)
  
  
  camera.capture(rawCapture,format='bgr')
  image=rawCapture.array
  
  cv2.imwrite('IMAGE.jpg',image)
  </code></pre>
  
  <p>Unfortunately the shell shows me this:</p>
  
  <pre><code>pi@LM-rasp:~/Documents $ python3 captureImage.py 
  Traceback (most recent call last):
    File "captureImage.py", line 3, in &lt;module&gt;
      from picamera.array import PiRGBArray
    File "/home/pi/Documents/picamera.py", line 3, in &lt;module&gt;
      from picamera import PiCamera 
  ImportError: cannot import name 'PiCamera'
  </code></pre>
  
  <p>I know it exists the same kind of issue for other people, but I don't succeed to fix this issue.
  Can you help me ?
  Thanks !</p>
