State: closed
Merged: Yes

Description

  • generalize module_import_helper for loading module from source
  • it's used for avoid repeated code by
    • importing a module from the source file directly
      • Check, import and update the module name into sys.modules, according to Python docs Importing a source file directly
      • Support to use lazy import loader (disabled by default), which creates a real module object but is not loaded into memory, according to Implementing lazy imports. It may help to improve faster launch time and prevent actual loading unused modules (for LLM models, built-in tools, etc.), when it's turned on by default in the future.
    • getting subclasses of targeted parent type from the module
