这可以通过使用le.inverse_transform()方法来实现。 总结:Label Encoding是一种简单的方法,用于将分类变量转换为机器学习模型可以理解的格式。它可以用于小规模数据集,但在处理大规模数据集时可能需要更复杂的标记方法。在使用Label Encoding时,应该注意将编码后的数据转换为数值型数据类型,并可能需要反向转换以获

ENCODINGCurrently, there is a significant amount of public code in the IT communities, programming forums and code repositories. Many of these codes lack classification labels, or have imprecise labels, which causes inconvenience to code management and retrieval. Some classification methods have been ...
Chinese characters typically use a different encoding than ASCII, such as UTF-8 or GBK. If the system’s default encoding does not support the Chinese characters used in your code, they will appear as distorted symbols or question marks. 解决方案 为了解决Label控件中文乱码的问题,我们需要进行以下...
— jsonPython 3 在标准库中包含了一个json模块。同pickle模块类似,json模块包含一些函数,可以序列化数据结构,保存序列化后的数据至磁盘,从磁盘上读取序列化后的数据,将数据反序列化成新的Pythone对象。但两者也有一些很重要的区别。 首先, json数据格式是基于文本的, 不是二进制的。RFC 4627定义了json格式以及怎...

Python制作一个简单的抽奖软件(二) 认识QT 因为都对 QT和tkinter都没用过,之前简单使用tkinter后发现,界面调整不太好弄。然后度娘了之后,QT是强大GUI库之一,很多人都推荐它。重新选择QT进行尝试。于是,就使用了PYQT5,是QT的python版本。 https://www.riverbankcomputing.com/software/pyqt/download5 使用到... ...
