I'm also having similar problems when loading modules... it only give me error when I try to use one of my modules...

Did you solve it?

      The last problem faced is in the rasberrypi's command line I cannot start the frame flow, so I use the remote desktop of win7 to connect the rasp 's X window, and I use the command of Xwindow .and the frame captured by the camera pop up which indicated the red blob locked. I do not know what is your problem.

        My problem is that if I have a module with functions it can never find it... in normal python it does not give me problems... but when doing it with droneapi, i always get this error:
        
        STABILIZE> api start pix-goto.py
        
        STABILIZE> Exception in APIThread-1: cannot import name vc Traceback (most recent call last): File "/usr/local/lib/python2.7/site-packages/droneapi/module/api.py", line 321, in run self.fn() File "/usr/local/lib/python2.7/site-packages/droneapi/module/api.py", line 592, in APIThread(self, lambda: execfile(args[1], g), args[1]) File "pix-goto.py", line 18, in from modules.vehicle import vc
        
        ImportError: cannot import name vc
        
        STABILIZE>
        
        My module is named vehicle.py and its inside a folder named modules, with its __init__.py

        I have never seen pix-goto.py ,which package is it contains in, some mission like go to a specifed destination?
        
        At first, The problem I faced is "@rmackay9 I put the code at https://github.com/diydrones/visual-followme on a rasberrypi which is connected to a APM ,and I start the mavproxy, do"module load droneapi.module.api",and typed api start drone_script.py ,and there is some error like below : " Exception in APIThread-0: No module named file_utils
        Traceback (most recent call last):
        File "/usr/local/lib/python2.7/dist-packages/droneapi/module/api.py", line 325, in run
        self.fn()
        File "/usr/local/lib/python2.7/dist-packages/droneapi/module/api.py", line 605, in <lambda>
        APIThread(self, lambda: execfile(args1, g), args1)
        File "drone_script.py", line 8, in <module>
        from file_utils import Logger
        ImportError: No module named file_utils"
        
        And someone told me to do this :"
        
        you have to add the python scripts' path to the python execution path. A brutal way, is to insert these commands at the top of drone_script.py
        import sys
        import os
        sys.path.insert(1, os.getcwd())
        
        "

somebody told me to add "import sys
import os
sys.path.insert(1, os.getcwd())"   on the top of the drone_script.py

and then the tips turns to be like below:

    The reacent situation:
