"No module named 'toga'" after installation

[bityob]

I installed toga (and verified it is truly updated):

C:\Users\myuser>pip install -U toga
Requirement already up-to-date: toga in d:\python35\lib\site-packages
Requirement already up-to-date: toga-win32; sys_platform == "win32" in d:\python35\lib\site-packages (from toga)
Requirement already up-to-date: toga-cassowary in d:\python35\lib\site-packages (from toga-win32; sys_platform == "win32"->toga)
Requirement already up-to-date: cassowary in d:\python35\lib\site-packages (from toga-cassowary->toga-win32; sys_platform == "win32"->toga)

but when I try to use it, I get "No module named 'toga'"

C:\Users\myuser>python

Unfortunately, Windows support is lagging a bit behind other platforms; some recent changes haven't been reflected in the Windows port.
