现在,核心贡献者都在使用Lightning推动AI的发展,并继续添加新的炫酷功能。 但是,简单的界面使专业的生产团队和新手可以使用Pytorch和PyTorch Lightning社区开发的最新技术。 Lightning拥有超过320名贡献者,由11名研究科学家,博士研究生和专业深度学习工程师组成的核心团队。
For example, Lightning automatically saves the model checkpoint by default as compared to Pytorch which expects the developer to insert that logic for checkpointing. Lightning also provides the logs of weights summary, checkpointing, early stopping, and tensorboard logs. ...
What is the primary advantage of using PyTorch Lightning over classic PyTorch? The primary advantage of using PyTorch Lightning is that it simplifies the deep learning workflow by eliminating boilerplate code, managing training loops, and providing built-in features for logging, checkpointing, and dis...
