python "Key Error"

[a9balsza]

i made an .fcl file in qtfuzzylite.I want to load it in python 2.7 with fcl Reader.It must do some calculation with the given inputs then it must give the output value.when i run the program it writes Key Error 'PNEU

I used this example: http://pyfuzzy.sourceforge.net/doc/quickstart.html

import fuzzy.storage.fcl.Reader
system = fuzzy.storage.fcl.Reader.Reader().load_from_file("Ballpositioner2.fcl")
 
# preallocate input and output values
my_input = {
        "REQ_POS" : 0.0,
        "REQ_ANGLE" : 0.0,
        "DESIRED" : 0.0,
        
        }
my_output = {
        "PNEU" : 3,
        }
 
# if you need only one calculation you do not need the while

        # set input values
my_input["REQ_POS"] = 10
my_input["REQ_ANGLE"] = 20
my_input["DESIRED"] = 30
        # calculate
        
system.calculate(my_input, my_output)
 
        # now use outputs
b = my_output["PNEU"]



line 3:0 extraneous input u'VAR_INPUT' expecting Identifier
