The error is raised because the tryton server does not find any model named _party.wps_

Normally the problem is because one of the following reasons:

- The model name is wrong
- The model is not registered on the pool (missing on ` __init__.py` file)

Hope it helps!

Thanks that u respond me, the problem was fixed , but now there is another error also about the menuitem during upgrading the code xml is:

```auto
<menuitem parent="menu_14555_d_wpqr_form" action="wizard_print_iso_wpqr2"
            id="menu_print_wpqr2" icon="tryton-print"/> 
<menuitem name = "EN ISO 14555-D" parent="menu_schweiss_wpqr_form" sequence="1"
             id="menu_14555_d_wpqr_form"/>
<menuitem name = "Creation of the certificate " parent="menu_14555_d_wpqr_form" sequence="1"
      action = "act_wpqr2_form" id="Creation _wpqr2_form"/>  

```

when i typed the command on linux: `trytond/bin/trytond-admin -c trytond.conf --all -d testd -vv`, it told me this error: Tag menuitem with id namemodule.menu\_print\_wpqr2

Now your problem is that you have set a parent xml\_id which does not exist.
