ImportError: No module named openerp
Odoo 10 source code does not contain the ./odoo.py file, it is probably from <=9.0, where the now odoo module was named openerp. You should've got the wrong source, or mixed up the two.
While running odoo at the first time it shows ImportError: No module named openerp
