🌟 Summary
Updated dependencies and streamlined Distributed Data Parallel (DDP) model instantiation.
📊 Key Changes
torchandtorchvisioninrequirements.txt, previously excluding problematic versions.train.pywith a newsmart_DDPfunction.train.py, resulting in cleaner code.smart_DDPfunction inutils/torch_utils.pythat includes version checks and conditions for DDP instantiation, ensuring compatibility and preventing usage with unsupported versions.🎯 Purpose & Impact
torchandtorchvisiondependencies may allow for wider compatibility with different versions of these libraries, potentially easing installation and upgrade processes.smart_DDPfunction centralizes DDP logic, making it easier to manage compatibility issues with PyTorch versions and reducing potential errors during multi-GPU training setups.train.pyandutils/torch_utils.py, the codebase becomes more maintainable and understandable, which benefits contributors and users alike.
