在该方法中,输入的数据batch被处理后,通过self.shared_step方法来计算loss。那这里可以简单理解为,我们为了获取数据,仅需要将调用模型的training_step方法,就无需再单独定义loss的计算方案了。 class DDPM(pl.LightningModule): ... def training_step(self, batch, batch_idx): for k in self.ucg_training: p...
pytorch-lightning 是建立在pytorch之上的高层次模型接口,pytorch-lightning之于pytorch,就如同keras之于tensorflow。 关于pytorch-lightning的完整入门介绍,可以参考我的另外一篇文章。 使用pytorch-lightning漂亮地进行深度学习研究 我用了约80行代码对 pytorch-lightning 做了进一步封装,使得对它不熟悉的用户可以用类似Keras...

pytorch lightning 与 torch 的对应关系 torch与pytorch的区别,因为有人问我optimizer的step为什么不能放在min-batch那个循环之外,还有optimizer.step和loss.backward的区别;那么我想把答案记录下来。首先需要明确optimzier优化器的作用,形象地来说,优化器就是需要根据
2. Shared file-system initialization file:// 共享文件系统(要求所有进程可以访问单个文件系统)有共享文件系统可以选择 提供的第二种方式是文件共享,机器有共享的文件系统,故可以采用这种方式,也避免了基于TCP的网络传输。这里使用方式是使用绝对路径在指定一个共享文件系统下不存在的文件。
