i have some problem, when i run py -tt first_ai.py a message like this appear :
File "first_ai.py", line 41
    NN = Neural_Network()
                        ^
IndentationError: unindent does not match any outer indentation level
my part of code is :
NN = Neural_Network()
   o = NN.forward(X)
   print("Sorti predit par l'IA : \n" + str(o))
   print("Vrai sorti : \n" str(y))
