Dronekit: OSError: [Errno 8] Exec format error

Hi! I have a problem with dronekit. I use python 2.7.9 and Raspberry Pi2mB (raspbian). When I try to run an example from this site http://python.dronekit.io/guide/quick_start.html
I get an error

APM:Copter V3.3.3 (acf2e10c)

I did connection by RC.
How I can resolve it? Thanks for any help!
P.S. Bellow is my code (simple_goto)
#!/usr/bin/env python

You’re not using a connect parameter, so it’s trying to start an SITL instance. It’s not intelligent enough to know that you’re on an ARM platform so it’s trying to run an intel binary on your raspberry.
Pass a connect parameter to your flight controller.

Thanks for answer!
But can you pleas explain what exactly I need to do? I am new in it, so it is difficult to understand) What does “run an intel binary on your raspberry” means?

It’s fine to discuss here as it is related to ArduPilot, but I’d like to point out that Dronekit has its own forum: https://discuss.dronekit.io/

Thank you, I didn’t know about that)
