I'm a newbie in Odoo and python. After tried to make a custom module based on tutorial on odoo v9 page, I found some trouble when running it. It said that can't find the module named openerp. 

Here's the text from my IDE :

        Traceback (most recent call last): File "C:/Program Files (x86)/Odoo 9.0-20160921/server/openerp/addons/openacademy/models/models.py", line 2, in <module> from openerp import models, fields, apiImportError: No module named openerp
