I created a simple module, that add custom field in partner module. But then I deleting this module in app manager, I can't access to partner module anymore. What I'm doing wrong?

So, this is my code: 

models.py

from odoo import models, fields, api
class ResPartnerInherited(models.Model):
    _inherit = 'res.partner'
    card_number = fields.Char(string="Card Number", required=False, )

views.xml

<odoo>
  <data>
    <!-- Inherit Form View to Modify it -->
    <record id="" model="ir.ui.view">
        <field name="name">res.partner.cardnumber.field</field>
        <field name="model">res.partner</field>
        <field name="inherit_id" ref="base.view_partner_form"/>
        <field name="arch" type="xml">
            <xpath expr="//field[@name='category_id']" position="after">
                <!-- Add your fields or attributes here -->
              <field name="card_number"/>
            </xpath>
        </field>
    </record>
  </data>
</odoo>

Error:
