在上一章中,我们已经使用 Keras 和 TensorFlow.js 库完成了两个基本的端到端项目。 我们已经熟悉 NumPy,pandas 和 Keras 等 Python 库,并且还了解了如何使用 JavaScript 开发深度学习模型。 我们还使用了 Flask 框架从深度学习模型中创建 API。 在“第 4 章”,“TensorFlow.js 入门”中,我们使用了第三方应用编...

This class defines a new kind of object that will have name and pay attributes (sometimes called state information), as well as two bits of behavior coded as functions (normally called methods). Calling the class like a function generates instances of our new type, and the class’s methods...

In mixed-mode debugging, these values present another child node labeled [Python view]. To view the variable's Python representation, expand the node. The view of the variables is identical to what you see if a local variable referencing the same object is present in a Python frame. The ...
