Hello  
I have a problem but i'm unable to find the solution.  
Using the python function i do  
from pigpio\_encoder.rotary import Rotary  
But i get the error : no module named pigpio\_encoder,  
I have this module if i import it from python shell i have no problem to run it  
sorry for my stupid question but it's the first time that i use node red  
Regards
