with open("cfnresponse.py", 'wb') as out_file, urllib3.PoolManager() as http:
    out_file.write(http.request('GET', github_raw_url).data)

# Add the package to your Python path
sys.path.append("cfnresponse.py")

# Import the cfnresponse module
from cfnresponse import register_handler, lambda_handler
