SystemError с spidev после обновления

Question

Я получаю следующую ошибку:Traceback (последний последний вызов): Файл "/home/hydro1/hydroponic_newloop.py", строка 6, в import spidevSystemError: Тип не определяет поле tp_name. Вот соответствующий код:

      #import os
import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BCM)
import time
import datetime
import spidev
from twilio.rest import Client
#from time import sleep
import csv
# Define I/O pins on PI
shutdown_trigger = 2
water_full_pin = 4
water_empty_pin = 5
water_on_pin = 6
irregation_on_pin = 13
fertilizer_empty_pin = 17
fertilizer_on_pin = 27
bubbler_on_pin = 22
water_heater_on_pin = 26
# Set up I/O pins on PI
GPIO.setwarnings(False)
GPIO.setup(shutdown_trigger, GPIO.OUT)
GPIO.setup(water_full_pin, GPIO.IN)
GPIO.setup(water_empty_pin, GPIO.IN)
GPIO.setup(water_on_pin, GPIO.OUT)
GPIO.setup(irregation_on_pin, GPIO.OUT)
GPIO.setup(fertilizer_empty_pin, GPIO.IN)
GPIO.setup(fertilizer_on_pin, GPIO.OUT)
GPIO.setup(bubbler_on_pin, GPIO.OUT)
GPIO.setup(water_heater_on_pin, GPIO.OUT)
# Initialize Output Pins to OFF on PI
GPIO.output(water_on_pin, GPIO.LOW)
GPIO.output(shutdown_trigger, GPIO.HIGH)
GPIO.output(fertilizer_on_pin, GPIO.LOW)
GPIO.output(bubbler_on_pin, GPIO.LOW)

# Open SPI bus for MCP3008 adc
spi = spidev.SpiDev()
spi.open(0,0)
spi.max_speed_hz=1000000
# Define sensor channels on MCP3008 adc
air_temp_channel = 0
water_temp_channel  = 1
battery_level_channel = 2
soil_moisture_channel = 3
grove_tds_channel = 4
# Function to read SPI data from MCP3008 chip
# Channel must be an integer 0-7
def ReadChannel(channel):
    adc = spi.xfer2([1,(8+channel)<<4,0])
    data = ((adc[1]&3) << 8) + adc[2]
    return data

это работало раньше, но не удалось после обновлений. работает Python 3.9.2. Любые идеи?
