## Summary of Changes Hello @junrushao, I'm Gemini Code Assist[^1]! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request enhances the module loading mechanisms by introducing a `keep_module_alive` flag to various loading APIs. This flag, enabled by default, ensures that dynamically loaded modules are persistently held in a global registry, preventing their premature unloading and addressing potential use-after-free errors. The change involves modifications to both the Python frontend and the C++ backend to manage module lifecycles more robustly. ### Highlights * **New `keep_module_alive` Flag**: Introduced a `keep_module_alive: bool = True` flag to `load_module`, `cpp.load_inline`, and `cpp.load` APIs. This flag, enabled by default, ensures that loaded modules are retained in a global registry, preventing premature unloading. * **Module Unloading Prevention**: When `keep_module_alive` is `True`, the module maintains a reference count within `ModuleGlobals` inside `libtvm_ffi.so`, preventing Python from unloading it until the program exits or it's manually closed. * **New Internal APIs**: Two private C++ FFI APIs, `_ffi_api.ModuleGlobalsAdd` and `_ffi_api.ModuleGlobalsRemove`, were added to manage the global module registry, allowing modules to be explicitly added or removed from the 'alive' list. * **Bug Fixes and Stability**: This change is intended to resolve existing issues #264 and #322, which likely relate to module unloading problems, and supersedes a previous attempt in #331, improving overall stability. <details> <summary><b>Using Gemini Code Assist</b></summary> <br> The full guide for Gemini Code Assist can be found on our [documentation page](https://developers.google.com/gemini-code-assist/docs/review-github-code), here are some quick tips. <b>Invoking Gemini</b> You can request assistance from Gemini at any point by creating a comment using either `/gemini <command>` or `@gemini-code-assist <command>`.
