Yahtzee 代码错误：具有多个元素的数组的真值不明确。使用 a.any() 或 a.all()

Question

这是我在 Yahtzee 中查找不同死亡案例概率的代码。我已经弄清楚了 yahtzee 和满屋方法。但是当我执行 is_it_large_straight 方法时，它给我一个错误：

The truth value of an array with more than one element is ambiguous. Use a.any() or a.all().

我需要更改我的代码中的哪些内容才能生成我想要的结果？

import numpy as np

    def __init__(self, sides):
        """A constructor method to create a die"""
        self.sides = sides

        return random.randint(1, self.sides)

Answer 1

在is_it_large_straight中替换

largestraight = self.count_outcomes()

和

largestraight = self.count_outcomes().tolist()

目前 largestraight 是一个 numpy 数组，它没有确定的布尔值，因此无法与您在 largestraight 中的列表进行比较 == [0,0,1,1,1,1,1 ]
