ValueError when db settings altered in settings.py Django documentation

Hi iam following Django documenatation,I have installed Django 1.8 and python 2.7.12,I want to connect to oracle 11g database,For this I have altered settings.py file in mysite folder like this for DATABASE information

DATABASES = {
    'default': {
        'ENGINE' : 'django.db.backends.oracle',
        'NAME' : 'XE',
        'USER' : 'chandan',
        'PASSWORD' : 'root',
        'HOST' : 'localhost',     }
}

Iam getting below error when i run python manage.py runserver and

python manage.py migrate

       from .utils import InsertIdVar, Oracle_datetime, convert_unicode
  File "C:\PYTHON27\lib\site-packages\django\db\backends\oracle\utils.py", line 10, in <module>
    (int(Database.version.split('.', 2)[1]) >= 1 or
ValueError: invalid literal for int() with base 10: '0rc1'

Do i have to alter my DATABASE part in settings.py or what needs to be done?
