Am launching a script taht trains a model which works well when trained without ddp and using gradient checkpointing, or using ddp but no gradient checkpointing, using fabric too. However, when setting both ddp

Every research project starts the same, a model, a training loop, validation loop, etc. As your research advances, you're likely to need distributed training, 16-bit precision, checkpointing, gradient accumulation, etc. Lightning sets up all the boilerplate state-of-the-art training for you ...
PyTorch’s autograd system is crucial for automatic differentiation and gradient computation. At this stage, you will learn it beyond its basics, including how to create computation graphs and handle gradients. These form the backbone of effective neural network training. Working with PyTorch’s ecosy...
