Django : import a module

I'm trying to control a LED with a raspberry pi from a Django application. I wrote a python script to set the color of the LED and everything is okey. However when I call the script from my views.py I got an AttributeError : module has no attribute.

Views.py

import sys, os
PROJECT_DIR = os.path.dirname(os.path.abspath(__file__))
sys.path.append(os.path.join(PROJECT_DIR, 'static/lampe/scripts'))
import launcher, lampe

"""Vue utilisee pour appliquer une couleur"""
class Appliquer_couleur(View):
  def get(self, context, **reponse_kwargs):
    print(self.kwargs['pk'])
    couleur_serialized = CouleurSerializer(Couleur.objects.get(pk=self.kwargs['pk']))
    launcher.launch(couleur_serialized.data['code'])
    return HttpResponse('')

In the directory "lampe/static/lampe/scripts" I have three files : an empty init.py, lampe.py and launcher.py

Lampe.py

import sys
import RPi.GPIO as GPIO
def setCouleur(arg1):
  ..

Launcher.py

import sys, os
from multiprocessing import Process

import lampe as LED

def launch(arg1):
  try:
    process = Process(target=LED.setCouleur, args=(arg1,))
    process.start()
    process.join()
  except KeyboardInterrupt:
    pass

if __name__== "__main__":
  sys.exit(launch(sys.argv[1]))

Traceback

the name of your project "lampe" is concealing the "lampe.py" in lampe/static/lampe/scripts as it is being found by python and importing it before importing the 'lampe.py' module. please rename your lampe.py and try again.
