Question

i am trying to make a software that records microphone data in realtime but it keeps on coming up with an error. " TypeError: init () got an unexpected keyword argument '__no_builder'" i have looked through the code but cant seem to find any problems. i am using atom to code. there is a .kv and .py file

python file
from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.garden.graph import MeshLinePlot
from kivy.clock import Clock
from threading import Thread
import audioop
import pyaudio
from kivy.core.window import Window
from kivy.lang import Builder

Window.borderless = True

def capture_mic_data():
    chunk = 1024
    FORMAT = pyaudio.paInt16
    CHANNELS = 1
    RATE : 44100
    p = pyaudio.PyAudio()
    s =  p.open(format = FORMAT, channels = CHANNELS, rate = RATE, input = True,frames_per_buffer =chunk)

    global levels
    while True:
        data =  s.read(chunk)
        mx = audio.rms(data,2)
        if len(levels) >= 100:
            levels = []
        levels.append(mx)

    def __init__(self,):
        super(Logic,self).__init__()

You must handle keyword arguments when you extend a class. Just add that to your Logic class:

class Logic(BoxLayout):

    def __init__(self, **kwargs):
        super(Logic,self).__init__(**kwargs)
        self.plot = MeshLinePlot(color=[1,0,0,1])
