Hi 

 I got an error , stopping my odoo service , running ubuntu 18.04 and odoo12 CE. Model 'ir.qweb.field.float' does not exist in registry.

Try to look around without success. I was obliged to implement CRON restarting the service over and over, each 10 minutes. After googling that, I didn't found any clear answer. Can somebody help?

   This is the error
