🌟 Summary
Enhanced PyTorch compatibility and optimized model training performance in multi-GPU setups.
📊 Key Changes
check_versionutility function to confirm PyTorch version compatibility.static_graphparameter in DDP based on PyTorch version check.🎯 Purpose & Impact
check_versionfunction ensures the training script is compatible with specific PyTorch versions; this prevents potential version-related errors for users.static_graph=Truewithtorch.nn.parallel.DistributedDataParallel(DDP) when available (PyTorch 1.11.0+) optimizes performance during training with static computational graphs, leading to potentially faster and more efficient multi-GPU training.
