I had error when trying to upload sensor value to Firebase but there's several error..

My python 3 is:

import RPi.GPIO as GPIO

import time

import pyrebase

import json



# change these as desired - they're the pins connected from the

# SPI port on the ADC to the Cobbler

SPICLK = 11

SPIMISO = 9

SPIMOSI = 10

SPICS = 8



# photoresistor connected to adc #0

photo_ch = 0



#port init

def init():

         GPIO.setwarnings(False)

         GPIO.cleanup()         #clean up at the end of your script

         GPIO.setmode(GPIO.BCM)     #to specify whilch pin numbering system

         # set up the SPI interface pins

         GPIO.setup(SPIMOSI, GPIO.OUT)

         GPIO.setup(SPIMISO, GPIO.IN)

         GPIO.setup(SPICLK, GPIO.OUT)

         GPIO.setup(SPICS, GPIO.OUT)



#read SPI data from MCP3008(or MCP3204) chip,8 possible adc's (0 thru 7)

def readadc(adcnum, clockpin, mosipin, misopin, cspin):

        if ((adcnum > 7) or (adcnum < 0)):

                return -1

        GPIO.output(cspin, True)    



        GPIO.output(clockpin, False)  # start clock low

        GPIO.output(cspin, False)     # bring CS low



        commandout = adcnum

        commandout |= 0x18  # start bit + single-ended bit

        commandout <<= 3    # we only need to send 5 bits here

        for i in range(5):

                if (commandout & 0x80):

                        GPIO.output(mosipin, True)

                else:

                        GPIO.output(mosipin, False)

                commandout <<= 1

                GPIO.output(clockpin, False)



        adcout = 0

        # read in one empty bit, one null bit and 10 ADC bits

        for i in range(12):

                GPIO.output(clockpin, True)

                GPIO.output(clockpin, False)

                adcout <<= 1

                if (GPIO.input(misopin)):

                        adcout |= 0x1



        GPIO.output(cspin, True)



        adcout >>= 1       # first bit is 'null' so drop it

        return adcout

         init()

         while True:

             adc_value=readadc(photo_ch, SPICLK, SPIMOSI, SPIMISO, SPICS)

             print(adc_value)

             return adc_value



             time.sleep(2)



   ##      time.sleep(2)

   ##      print("will start detec water leveln")

   ##      while True:

   ##               adc_value=readadc(photo_ch, SPICLK, SPIMOSI, SPIMISO, SPICS)

   ##               if adc_value == 0:

   ##                        print("no watern")

   ##               elif adc_value>0 and adc_value<30 :

   ##                        print("it is raindropn")

                  #print "adc_value= " +str(adc_value)+"n"

    ##              time.sleep(1)



while True:



    config = {

      "apiKey": "AIzaSyD-4PQ_BsXn-g9KWf-iv-BbE5HeYYehYbE",

      "authDomain": "myapplication-8ca28.firebaseapp.com",

      "databaseURL": "https://myapplication-8ca28.firebaseio.com/",

      "storageBucket": "myapplication-8ca28.appspot.com"

    }

    firebase = pyrebase.initialize_app(config)

    db = firebase.database()

    postdata = {

        'Weight': int(main())

    }

    results = db.child("WeightR").child("Weight").update(postdata)

And the error i had are:

I install via sudo pip install pyrebase,sudo pip3 install pyrebase and pip install pyrebase.. Initially theres's error with installing them, but after use sudo there's some entry ignore but able to install.
