The Python implementation ships transcribe() / detect_language() / load_model() APIs over a PyTorch backend. Imports as plain "whisper"; conflicts with dev-python/whisper (Graphite round-robin DB — same name, unrelated upstream). The Triton fastpath (triton>=2 from upstream's optional dep) is not pulled here; it would speed up long-form decoding but isn't packaged on this overlay yet. Functional fallback is pure-PyTorch.

  Description: GObject is a object system used by GTK+, GStreamer and other libraries. PyGObject provides a convenient wrapper for use in Python programs when accessing GObject libraries. Like the GObject library itself PyGObject is licensed under the GNU LGPL, so is suitable for use in both free software and proprietary applications. It is already in use in many applications ranging from small single purpose scripts up to large full featured applications. PyGObject now dynamically accesses any GObject libraries that uses GObject Introspection. It replaces the need for separate modules such as PyGTK, GIO and python-gnome to build a full GNOME 3.0 application. Once new functionality is added to gobject library it is instantly available as a Python API without the need for intermediate Python glue.
