Hey everyone! Excellent site! I'm a Python/Java newb in need of help. I just installed the current MRL and the latest Java (9). I tested the Opencv face-tracking on the GUI interface and it tracks my face fine on my built-in laptop camera.

But in trying to set up a Python connection to my Arduino Uno board so I can set up a moving camera to follow faces, I can't get past these syntax errors. I've formatted this code (Face_Detect_Serial.py from docs at Google) as best I know how, but all the imports were troublesome. As you can see, I've had to import entire libs like java.lang instead of just using the 'from' parameter. But if that still gets me what I want, I can live with it for now.

My real problem is getting two opencv imports going. I've highlighted the code and the error messages in order below that. I'm a dinosaur coder from the COBOL days, but I've worked in BASIC & VB, and with Arduinos fore a year now, so I'm starting to get comfortable in C++. But I'm too new to Python to know how to handle libs with opencv.

I get that this is a lot of verbeage - I'm funny that way - but I'd sure appreciate some help:

# This code creates an opencv service and tracks a face.
# It thens finds the center of the face and converts the position to a scale of 1-100
# This information is then sent via serial service to any receiving device
# If the script needs to be restarted, completely close MRL and reopen it.
