django tzinfo = utc now found while using datetime and utc

Question

while performing a test case for my model named Device I found and error in my terminal the error is

======================================================================
FAIL: test_device (farm_management.test.test_models.TestDevice)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/home/admin123/igrow-api/app/farm_management/test/test_models.py", line 68, in test_device

AssertionError: datetime.datetime(2022, 1, 12, 9, 35, 19, 280416, tzinfo=<UTC>) != datetime.datetime(2022, 1, 12, 9, 35, 19, 281136)

I think this means I made some mistake while importing the datetime and utc

test file codes are here

import datetime

from django.test import TestCase
from django.db.utils import IntegrityError
from farm_management.models import Farm, Device, BatchYield, Batch



class TestDevice(TestCase):

    def setUp(self):

        self.device1 = Device.objects.create(
            id="C004825",
            fetch_status="1",
            last_fetched_on=datetime.datetime.utcnow(),
            geolocation="28.48064,77.09301",
            device_status="inactive",
            is_active="1",



        )

    def test_device(self):
        self.assertEqual(self.device1.id, "C004825")
        self.assertEqual(self.device1.fetch_status, "1")
        self.assertEqual(self.device1.last_fetched_on, datetime.datetime.utcnow())
        self.assertEqual(self.device1.geolocation, "28.48064,77.09301")
        self.assertEqual(self.device1.device_status, "inactive")
        self.assertEqual(self.device1.is_active, "1")

I just don't that how can i get the matching output which shows in my terminal and
