Not able to access appium driver methods

Support
1

I am trying to get instance of appium webdriver, but ended up getting selenium webdriver instance, below i am sharing what I did
When I print I get selenium webdriver see below
<selenium.webdriver.remote.webdriver.WebDriver (session=“e5145007-a51c-4644-8fd2-01db5e3d92d2”)>

Code:

class IOSTests(unittest.TestCase):

def setUp(self):
    # set up appium
    app = PATH('../apks/StreetReader.app')
    self.driver = webdriver.Remote(
        command_executor='http://127.0.0.1:4723/wd/hub',
        desired_capabilities={
            'platformName': 'iOS',
            'platformVersion': PLATFORM_VERSION,
            'deviceName': DEVICE_NAME,
            'app': app
        })
    print self.driver

def test_login(self):
    print self.driver
    CommonWrappers.login(self)
    el = self.driver.push_file(media_file, data.encode('base64'))

Error I get:
AttributeError: ‘WebDriver’ object has no attribute ‘push_file’
