If you need to add functionalities to the `button_validate` method you need to extend it.
class StockPickingInherit(models.Model):
_inherit = "stock.picking"

def button_validate(self):
# add your stuff
# ..
return super().button_validate()

# If tou don't want change the original behaviour of the method you can create a new one
def validate(self):
# add your stuff
return self.button_validate()

Thanks for the help but it was not what I really needed what I served was the following
from odoo.addons.stock.models import stock_picking  def button_validate1(self):
if not self.quien_elabora:
var = stock_picking
var.Picking.button_validate(self)
self.quien_elabora = str(self.env.user.name)
