load_iris 是来自 sklearn 的函数。该链接提供文档: iris 在您的代码中将是一个类似字典的对象。 X and y will be numpy arrays, and names has the array of possible targets as text (rather than numeric values as in y)。 原文由 Arya McCarthy 发布,翻译遵循 CC BY-SA 4.0 许可协议 有用 回复 ...

调用load data函数Python后存储数据集 是指在Python编程语言中使用load data函数来加载数据集,并将其存储在内存中以供后续处理和分析。 load data函数是Python中的一个内置函数,用于从外部文件或数据库中加载数据。它可以读取各种格式的数据,如文本文件、CSV文件、Excel文件、JSON文件等。 一般情况下,我们可以使用以下...
The Palmer penguins dataset by Allison Horst, Alison Hill, and Kristen Gorman was first made publicly available as an R package. The goal of the Palmer Penguins dataset is to replace the highly overused Iris dataset for data exploration & visualization. Using this python package you can easily ...

报错key words: b'Iris-setosa' 通过搜索原因,发现有可能是在对文件读取是编译出现了问题,并且Keyword中提示b'Iris-setosa',而我们的string转float函数中没有字母b,很奇怪。所以尝试将转换函数所有的string前加b。结果发现数据读取正常。 下边附上转换函数: ...
