Getting this error in DJANGO when trying to make a record inSQL

Question

Not sure why I am getting this error when I try to call a function within my load_data()

django.core.exceptions.ImproperlyConfigured: Requested setting INSTALLED_APPS, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

However, when I run the crud_ops.py function it works fine and sets the records within the database

load_data.py

def publisher_data(listt, start):
    from reviews.models import Publisher
    check_list = []
    query_list = []

    for i in range(start + 1, len(listt)):
        if listt[i].__contains__("publisher"):
            check_list.append(listt[i])
        else:
            query_list.append(listt[i])

        if len(query_list) == len(check_list):
            print(query_list)
            publisher = Publisher(name=query_list[0], website=query_list[1],
                                  email=query_list[2])
            publisher.save()

            query_list = []
        if listt[i].__contains__("content"):
            break

def load_data():

   file_read = open("WebDevWithDjangoData.csv", "r")
   text = file_read.read().split(",")
   new_list = [x for x in text if x.strip() != '']
   list_1 = []
   start_index = None
   end_index = None
   for x in new_list:
       list_1.append(x.strip())
   file_read.close()


  for x in range(len(list_1)):
       #print(list_1[x])
       if list_1[x] == "content:Publisher":
          start_index = x
          publisher_data(list_1, start_index)

crud_ops.py:

def crud_ops():
    from reviews.models import Publisher, Contributor
    publisher = Publisher(name='Packt Publishing', website='https://www.packtpub.com', email='info@packtpub.com')
    publisher.save()
    publisher.email = 'customersupport@packtpub.com'
    publisher.save()
    print(publisher.email)
    contributor = Contributor.objects.create(first_names="Rowel", last_names="Atienza",
                                             email="RowelAtienza@example.com")
    print(contributor)
    print('\n>>> END <<<')
