In data wine : 没有‘wine’这个数据集
Websklearn.datasets.load_wine(*, return_X_y=False, as_frame=False) 加载并返回 wine 数据集(分类)。 wine 数据集是一个经典且非常简单的multi-class 分类数据集。 WebJun 24, 2015 · The information regarding the variables states that scale of wine quality is from 0 to 10. However, the range of wine qualities in this dataset is 3 to 9. The mean is 5.878 and the median is 6. Many of the other variables have fairly extreme outliers on the higher end of scale, frequently a multiple of the 3rd quartile value.
