Can be used on CPU, GPU or TPUs. max_epochs: Stop training once this number of epochs is reached. Disabled by default (None).

Multi-GPU training — PyTorch Lightning 1.4.5 documentation Multi-GPU training Lightning supports multiple ways of doing distributed training. Preparing your code To train on CPU/GPU/TPU without changing your code, we need to build a few good habits :) Delete .cuda () or .to () calls Delete any calls to .cuda () or .to (device).

PyTorch Lightning is a framework which brings structure into training PyTorch models. It aims to avoid boilerplate code, so you don’t have to write the same training loops all over again when building a new model.

What is PyTorch lightning? Lightning makes coding complex networks simple. Spend more time on research, less on engineering. It is fully flexible to fit any use case and built on pure PyTorch so there is no need to learn a new language. A quick refactor will allow you to: Run your code on any hardware Performance & bottleneck profiler
