Hello,
I'm trying to run the ramp.py code on Wing IDE, and I keep getting the following error:

Exception in thread Thread-1 (most likely raised during interpreter shutdown):
Traceback (most recent call last):
  File "/usr/lib/python2.7/threading.py", line 810, in __bootstrap_inner
  File "/home/bitcraze/projects/crazyflie-lib-python/examples/cflib/crazyflie/__init__.py", line 373, in run
  File "/home/bitcraze/projects/crazyflie-lib-python/examples/cflib/crtp/radiodriver.py", line 232, in receive_packet
<type 'exceptions.AttributeError'>: 'NoneType' object has no attribute 'Empty'

Does anyone know how to fix this? I haven't modified anything in the code, and a couple of days ago this was working fine.

Thanks very much,

f-

This could be a bug related to Python2, can you run with Python3 to see if it work then?

HI Arnaud,

sorry for the late reply. Wing IDE seems to be having some trouble dealing with Python 3 and 3.4. I switched to PyCharm with Python 3.4 and now the code works fine

Hi,

This confirms that we have a bug in python2, I created a ticket for it https://github.com/bitcraze/crazyflie-l ... /issues/51.

Thanks for reporting that it works
