pytorch-lightning pytorch-lightning的wandb 由于最近涉及下游任务微调,预训练任务中的框架使用的是pytorch-lightning,使用了典型的VLP(vision-language modeling)的训练架构,如Vilt代码中:https://github.com/dandelin/ViLT,这类架构中只涉及到预训练,但是在下游任务中微调没有出现如何调参的过程。因此可以使用wandb的sweep...
Luca Antiga,grid.ai 的首席技术官, PyTorch Lightning 的主要维护者之一: "PyTorch 2.0 体现了深度学习框架的未来。不需要用户干预即可捕获 PyTorch 程序,开箱即用的程序生成,以及巨大的设备加速,这种可能性为人工智能开发人员打开了一个全新的维度。" 动机 PyTorch 的理念一直是将灵活性和可编程性(hackability)放在...
Now that you’ve loaded and properly understood the AN4 dataset, look at how to use NGC to load an ASR model to be fine-tuned with PyTorch Lightning. NeMo’s ASR collection comes with many building blocks and even complete models that you can use for training and evalu...
另外Santosh Gupta的SpeedTorch也值得一试,尽管其加速与否尚不完全清除。 8.使用梯度/激活检查点 检查点通过将计算保存到内存来工作。检查点在反向传播算法过程中并不保存计算图的中间激活,而是在反向传播时重新计算,其可用于模型的任何部分。 具体来说,在前向传播中,function以torch.no_grad()方式运行,不存储任何中...
Our most popular deep learning frameworks for training and inference are updated monthly.

Lightning has dozens of integrations with popular machine learning tools. Tested rigorously with every new PR. We test every combination of PyTorch and Python supported versions, every OS, multi GPUs and even TPUs. Minimal running speed overhead (about 300 ms per epoch compared with pure PyTorch...
How is this different from https://pytorch-lightning.readthedocs.io/en/latest/guides/speed.html ? I think the target for the doc is to highlights sections/points that can slow down/affect the performance when using PL for eg in case a user compares PL vs PT. And not just slow downs, ...
其中有加速训练的技巧。PyTorch Lightning已经处理了上面默认的一些点。 Hugging Face的Thomas Wolf有很多关于加速深度学习的有趣文章,其中特别关注语言模型。 Sylvain Gugger和Jeremy Howard也有一些文章: 关于学习率策略的:https://sgugger.github.io/the-1cycle-policy.html, ...
If our model has a low speed of training, it might be because of histogram logging. Previous Next Histograms are added using add_histogram() #defining the model class smallAndSmartModel(pl.LightningModule): ''' other necessary functions already written ''' def custom_histogram_adder(...
