Extending own class in PHP CodeIgniter 3

I have two models: models/Categories.php and models/backend/BE_categories.php

I want BE_categories class to extend Categories, since it has some useful functions I can re-use:

Categories.php

class Categories extends CI_Model
{
...

BE_categories.php

class Be_categories extends Categories
{
...

But when $this->load->model('models/be_categories') I get the error: Unable to locate the specified class: Session.php yet it works with exending CI_Model What have I done wrong?

I also had a Controller called Categories.php, with class Categories, which is where CI was getting confused.

I had to rename models/Categories.php to models/Categories_model.php as well as the class name.

But also had to include the file when extending:

BE_categories_model.php

include('application/models/Categories_model.php');
class Be_categories_model extends Categories_model
{
...

Edit:

Thanks to commenter, might be better to to include this model in config/autoload.php instead of using PHP's include() function.

Just my guess, you load Session library inside some function in Categories model,and then try to use function with session library specific function inside model BE_Categories.

Add Session library in config/autoload.php or load it inside Categories model constructor, and remember to add constructor inside BE_Categories.
