图1-1. 二维向量加法示例;Vector(2, 4) + Vector(2, 1) 的结果是 Vector(4, 5)。 我们将通过编写一个模拟控制台会话来开始设计这个类的 API,稍后我们可以将其用作文档测试。下面的代码片段测试了图 1-1 中所示的向量加法: >>>v1 = Vector(2,4)>>>v2 = Vector(2,1)>>>v1 + v2 Vector(4,...

It’s included with the Python installer, and it’s an essential tool for dependency management in Python. In this tutorial, you learned how to: Set up and run pip in your working environment Fix common errors related to working with pip Install and uninstall packages with pip Define ...
If you run an old version of Setuptools, it will also throw the "python setup.py egg_info" failed with error code 1. Missing ez_setup. ez_setup is another essential module required for python programming. Your system must have it installed; otherwise, you can get "python setup.py egg_...
Encrypting embeddings is essential for higher security applications to prevent adversarial attacks that could manipulate or extract sensitive information. Traditional encryption methods like AES are very safe but limited in securely utilizing cloud computational power for distance calculations. Herein, ...
opencv-python(modulecv2) is an imaging library built around numpy arrays. It can be used in the rendering CLI to save with pypdfium2's numpy adapter. pypdfium2 tries to defer imports of optional dependencies until they are actually needed, so there should be no startup overhead if you ...
