Pytorch Lightning: Advanced Framework of Pytorch

PyTorch Lightning is a lightweight PyTorch wrapper that provides a high-level interface for training PyTorch models. It is designed to simplify and standardize the training loop, making it easier to write cleaner, more modular code for deep learning projects. PyTorch Lightning introduces a set of abstractions and conventions that remove boilerplate code and allow researchers and practitioners to focus more on the model architecture and experiment configurations....

Pytorch vs Pytorch Lightning

PyTorch and PyTorch Lightning are both frameworks for building and training neural network models, but they differ in terms of abstraction, structure, and ease of use. Here are some key differences between PyTorch and PyTorch Lightning:...

Implementation: From Pytorch to Pytorch Lightning

Let’s illustrate the difference in code between a basic PyTorch script and its equivalent using PyTorch Lightning. Consider a simple training script for a neural network in both PyTorch and PyTorch Lightning....
