Will appreciate any help
thanks

Answer 1

The problem is in this .py file
/opt/odoo/addons/opencart_erp_connector/core_updated_files.py
Now go to above path (line no 23) and change the import statement
import pooler
to
from openerp import pooler
Restart server and refresh the browser.
Hope this will solve your problem.

Answer 2

Okay, Please do a small change in account_test.py, add import file from from openerp import pooler. Save and restart the server.

Answer 3

What is the filestructure of your custom module?
Can you provide us the filenames and some code?
it should be something like:
__init__.py
__pooler__.py
pooler.py
The __init__.py should contain:
import pooler
