Not able to connect to openstackusing libcloud

I am trying to use the lib cloud library to connect to my local openstack installation.

below is the code I am trying to execute:

from libcloud.compute.types import Provider
from libcloud.compute.providers import get_driver

1. Authentication information so you can authenticate to DreamCompute
2. copy the details from the OpenStack RC file
3. https://dashboard.dreamcompute.com/project/access_and_security/api_access/openrc/

auth_username = 'admin'
auth_password = 'f882e2f4eaad434c'
TENANT_NAME = 'admin'
project_name = 'admin'
auth_url = 'http://192.168.56.101:5000'
#auth_url = 'http://192.168.56.101:5000'
region_name = 'RegionOne'

OpenStack = get_driver(Provider.OPENSTACK)
driver = OpenStack('auth_username',
'auth_password',
ex_force_auth_url=auth_url,
ex_force_base_url='http://192.168.56.101',
ex_force_auth_version='2.0_password',
ex_tenant_name='admin',
ex_force_service_name='nova',
ex_force_service_region=region_name)

print(dir(driver.list_nodes))
print(driver.api_name)
print(driver.VOLUME_STATE_MAP)
#print(driver.connection.auth_user_info)
images = driver.name
print(driver.list_volumes())
"""for image in images:
print(image)
"""

However I keep getting the error message resource not found:
