title: Attribute Error: MultiTracker_create() Not Found in cv2 on Raspberry Pi
body: <p>I am currently trying to set up the opencv trackers on a Raspberry Pi. However, when I use the MultiTracker_create() function, it gives me an Attribution Error:</p>
  
  <pre><code>multiTracker = cv2.MultiTracker_create()
  </code></pre>
  
  <p>AttributeError: module 'cv2.cv2' has no attribute 'MultiTracker_create'</p>
  
  <p>The same code works on my computer, but when I try it on the Pi, it experiences the above error. I am currently using Python 3.5 on the Raspi with OpenCV 3.4.4. My computer uses Python 3.7 with OpenCV 3.4.1.</p>
  
  <p>Thank you in advance for your help. </p>
  
  <p>I have made sure that I am using the correct package: 
  pip3 install opencv_contrib_python </p>
  
  <p>I have also tried to look through the help(cv2) and could not find anything specific about the MultiTracker. </p>
