numpy.random.RandomState()函数用法可以通过numpy工具包生成模拟数据集,使用RandomState获得随机数生成器 from numpy.random import RandomState rdm = RandomState(1)注意:这里1为随机数种子,只要随机数种子seed相同,产生的随机数系列就相同 a = rdm.uniform(1,2,(3,4)
如果错误仍然存在,仔细检查代码中的其他可能问题。 综上所述,你需要检查你的代码中是否误用了 numpy.random.mtrand.RandomState 对象的属性或方法名,并确保所有变量都已正确定义和赋值。如果问题仍然存在,可能需要更详细地检查代码上下文或提供更多的代码片段以便进一步分析。
