Solution1:

First make sure that you added the py file to __init__.py .

Second: Your inherited view shows its inherited from openeducat_exam, make sure that it's add to depends modules in __manifest__.py file.

Then:

- Restart the service.

- Upgrade your module.

Solution 2:

Comment the below line in view:

<field name="assignment_marks"/>

and then restart the service and upgrade your module and check if the field created in the DB from settings -> Technical -> Models ->   then search for op.marksheet.line and check if the field created.

Then you can uncomment the above line and restart the service and upgrade the module.
