Hi,

Seems like "university.student" module is not present at Odoo end that's why you were getting this issue.
There can be either two reasons,

Either "university.student" is not defined inside the __init__.py file. So if not defined then please define this model inside the __init__.py file.
Else sequence of this module inside the __init__.py is incorrect. I mean if "university.student" model is used in other model(like relational field) then that model should be define after "university.student" model.
- For example we have two files A.py and B.py.
- And model of B.py is used in A.py file then you need define file like below,
- - ```
  from . import B 
  from . import A
```
