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)
PX4: 34e1d543 NuttX: 7c5ef883
Frame: HEXA
PX4v2 002C0023 31334704 39343031
PreArm: Throttle below Failsafe
Starting copter simulator (SITL)
SITL already Downloaded and Extracted.
Ready to boot.
Traceback (most recent call last):

OSError: [Errno 8] Exec format error
I did connection by RC.
How I can resolve it? Thanks for any help!
P.S. Bellow is my code (simple_goto)
