I follow a tutorial test kivy like below:

from kivy.app import App

# importing builder from kivy
from kivy.lang import Builder


# this is the main class which will
# render the whole application
class uiApp(App):

	# method which will render our application
	def build(self):
		return Builder.load_string(

			BoxLayout:
			size_hint: (1, 1)
			ScrollView:

			# here we can set bar color
			bar_color: [0, 0, 255, 1]

			# here we can set bar width
			bar_width: 12

			BoxLayout:



			size: (self.parent.width, self.parent.height-1)
			id: container
			orientation: "vertical"
			size_hint_y: None

			height: self.minimum_height

			canvas.before:
			Color:

			rgba: rgba("#50C878")
			Rectangle:

			pos: self.pos
			size: self.size

			Label:
			size_hint: (1, None)
			height: 300
			markup: True
			text: "[size=78]GeeksForGeeks[/size]"
			Label:
			size_hint: (1, None)
			height: 300
			markup: True
			text: "[size=78]GeeksForGeeks[/size]"
			Label:
			size_hint: (1, None)
			height: 300
			markup: True
			text: "[size=78]GeeksForGeeks[/size]"
			Label:
			size_hint: (1, None)
			height: 300
			markup: True
			text: "[size=78]GeeksForGeeks[/size]"

		)


# running the application
uiApp().run()

Error:
  File "/home/mc3/kivy_test.py", line 15
    BoxLayout:

What's problem?

load_string() takes a string as an argument. Wrap your config commands in quotes. Use triple quotes for a multiline string.
