在“第 3 章”和“创建第一个深度学习 Web 应用”中,我们看到了如何使用 Python 编写 Flask API,我们看到了如何在 Web 应用中使用该 API。 现在,我们知道 API 与语言库的区别以及使用 API的重要性。 我们熟悉一些顶尖组织提供的各种深度学习 API。 在接下来的章节中,我们将了解如何使用这些 API 来构

The memory usage in PyTorch is extremely efficient compared to Torch or some of the alternatives. We've written custom memory allocators for the GPU to make sure that your deep learning models are maximally memory efficient. This enables you to train bigger deep learning models than before. ...
