Here is the code:

import os, sys, io
import M5
from M5 import *
from unit import IRUnit



ir_0 = None


data = None
addr = None


def ir_0_rx_event(_data, _addr, _ctrl):
  global ir_0, data, addr
  data = _data
  addr = _addr
  print(data)


def setup():
  global ir_0, data, addr

  M5.begin()
  ir_0 = IRUnit((1, 2))
  ir_0.rx_cb(ir_0_rx_event)
  data = 0
  addr = 27


def loop():
  global ir_0, data, addr
  M5.update()


if __name__ == '__main__':
  try:
    setup()
    while True:
      loop()
  except (Exception, KeyboardInterrupt) as e:
    try:
      from utility import print_error_msg
      print_error_msg(e)
    except ImportError:
      print("please update to latest firmware")

I get error:

Traceback (most recent call last):
  File "<stdin>", line 25, in <module>
  File "<stdin>", line 17, in setup

The only thing that is different from the YouTube video is instead of setting a label to print the data value I am printing it to console, could this be the problem?
