Settings Codeigniter 3 HMVC with tank auth

Question

I'm trying to install Auth Tank in CodeIgniter in HMVC but without success. I did the following:

• I created the tables in the database;
• I put the folders (config, controllers, helpers, language, libraries, models, views) within modules/auth/;
• In application/config/routes.php I added the route to the Auth Tank: $Route["auth"] = "auth/login";;
• In Controller auth.php I changed $this->lang->load('tank_auth'); to $this->lang->load('auth/tank_auth');
• I changed the controller files to extends MY_Controller (that extends MX_Controller)

After this continues this error:

An uncaught Exception was encountered

Type: RuntimeException

Message: Unable to locate the model you have specified: Login_attempts

Has anyone implemented this library that can help me?

Thank you
