本文的代码都有解释,非常适合图像描述任务的入门读者详细了解这一过程。 图像描述是一个有挑战性的人工智能问题,涉及为给定图像生成文本描述。 字幕生成是一个有挑战性的人工智能问题,涉及为给定图像生成文本描述。 一般图像描述或字幕生成需要使用计算机视觉方法来了解图像内容,也需要自然语言处理模型将对图像的理解转换成...
Let’s walk through a couple of ways to do this. Here’s a contrived example of a lottery simulator using code that isn’t Pythonic on purpose. You’re developing an online lottery game where users can wager on their lucky number: Python import random class Lottery(object): def __init...
从nostarch.com/automatestuff2下载文本文件dictionary.txt。这个字典文件包含超过 44,000 个英语单词,每行一个单词。 使用你在第 9 章中学到的文件读取技巧,通过阅读这个文件创建一个单词串列表。然后遍历列表中的每个单词,将其传递给decrypt()方法。如果这个方法返回整数0,密码是错误的,你的程序应该继续下一个密码...
