FAQPage Schema
How do I scale PyTorch neural network training across multiple GPUs?▼

Scale PyTorch neural network training across multiple GPUs by organizing code into LightningModules and using the Trainer to automate distributed strategies like DDP, FSDP, and DeepSpeed.

What is the best way to manage PyTorch data loading and preprocessing pipelines?▼

Manage PyTorch data pipelines by encapsulating loading and preprocessing logic within a LightningDataModule, ensuring reusable and structured data delivery for scalable neural network training.

Can I use mixed precision and experiment logging for distributed PyTorch training?▼

Mixed precision and experiment logging are natively supported for distributed PyTorch training, allowing automatic integration with tracking tools like Weights & Biases and TensorBoard via custom callbacks.

How does PyTorch Lightning organize deep learning code for maintainability?▼

PyTorch Lightning organizes deep learning code by structuring models into LightningModules, separating data logic into LightningDataModules, and automating boilerplate training workflows for better maintainability.

Do I need to write custom code to orchestrate multi-GPU training with DeepSpeed?▼

No custom orchestration code is needed for multi-GPU training with DeepSpeed, as the Trainer automates complex distributed training workflows, mixed precision, and fault-tolerant model checkpointing.
