ImportError: cannot import name 'Irt'

[Jason8Kang]

I do as the demo,but get the error Type "help", "copyright", "credits" or "license" for more information.

from future import print_function, division, unicode_literals from psy import Irt, data Traceback (most recent call last): File "", line 1, in ImportError: cannot import name 'Irt'

Thats because the package is " irt " and not " Irt " . I would recommend to close this issue
