传递random_state给.sample(),就像@jose_bacoy建议的那样,是最简单和最好的方法。有时这不是一个选择/会很尴尬(例如,在使用pd.NamedAgg进行复杂的groupby聚合时,无法传递像random_state这样的参数)。 在这种情况下,您可以直接使用np.random.seed,它也适用于pandas。 示例: ...
在云计算领域,np.random.seed是一个用于设置随机数生成器种子的函数,而pd.sample是pandas库中用于从数据集中随机抽样的方法。如果想要像np.random.seed一样向pd.sample播种,可以使用pandas库中的random模块来实现。 具体步骤如下: 导入pandas库和random模块: ...
