WebApr 4, 2024 · lightning 是pytorch的轻量级高层API,类似keras之于tensorflow。它利用hook将主要逻辑拆分成不同step,如training_step,validation_step, test_step等,只需为你的模型重写这些需要的方法实现相应的逻辑,给入数据集加载器和创建的模型以实例化Trainer,然后就可以调用fit()训练。 Webpytorch是有缺陷的,例如要用半精度训练、BatchNorm参数同步、单机多卡训练,则要安排一下Apex,Apex安装也是很烦啊,我个人经历是各种报错,安装好了程序还是各种报错,而pl则不同,这些全部都安排,而且只要设置一下参数就可以了。另外,根据我训练的模型,4张卡的训练速...

WebApr 11, 2024 · Pytorch lightning fit in a loop. I'm training a time series N-HiTS model (pyrorch forecasting) and need to implement a cross validation on time series my data for training, which requires changing training and validation datasets every n epochs. I cannot fit all my data at once because I need to preserve the temporal order in my training data. WebIn normal PyTorch code, the data cleaning/preparation is usually scattered across many files. This makes sharing and reusing the exact splits and transforms across projects impossible. ...
