Depends used in a class takes up memoty more than 100Mb

[Spirit412]

I have a code where Depends is used in a class to implement methods of other classes. When the application is launched, this class takes up memoty more than 100Mb Here is an example:

How to optimize such code?

` class OrderFactory:

def __init__(self,
             user_access_controls_validate: ValidateCustomRole = Depends(),
             security_scope_validate: ValidateSecurityScope = Depends(),
             validate_security_scope: ValidateSecurityScope = Depends(),
             user_access_controls_factory: UserAccessControlsFactory = Depends(),
             security_factory: SecurityFactory = Depends(),
             current_user=Depends(get_current_user),
             order_service: OrderService = Depends(),
             validator_service: ValidatorService = Depends(),
             custom_validator_service: CustomValidatorService = Depends(),
             organization_partnership_service: OrganizationPartnershipService = Depends(),
             contract_service: ContractService = Depends(),
             order_status_service: OrderStatusService = Depends(),
             order_line_item_factory: OrderLineItemFactory = Depends(),
             email_factory: EmailFactory = Depends(),
             sales_point_service: SalesPointService = Depends(),
             order_line_item_service: OrderLineItemService = Depends()):

    self.user_access_controls_validate = user_access_controls_validate
    self.security_scope_validate = security_scope_validate
    self.validate_security_scope = validate_security_scope
    self.user_access_controls_factory = user_access_controls_factory
    self.security_factory = security_factory
    self.current_user = current_user
    self.order_service = order_service
    self.validator_service = validator_service
    self.custom_validator_service = custom_validator_service
    self.organization_partnership_service = organization_partnership_service
    self.contract_service = contract_service
    self.order_status_service = order_status_service
    self.order_line_item_factory = order_line_item_factory
    self.email_factory = email_factory
    self.sales_point_service = sales_point_service
    self.order_line_item_service = order_line_item_service

` The whole project is 2 MB. After the start of the project, 800MB of memory is used

Looks like you misunderstood how Depends works: it takes a Callable which in turn provides the actual value you're depending on. For example:

def get_db():
  try:
    db = Database()
    yield db
  finally:
    db.close()

Now, you'd use that like

def foo(db: Database = Depends(get_db), ...):
  pass

I'm not sure if that's what's causing your memory issue, but it certainly isn't helping it.
