rng = np.random.default_rng(seed=2310) rng.integers(low=1, high=6, endpoint=True, size=1) 使用.integers() 并指定要在 1 到 6 的范围内(包括边界)抽样整数。接下来可以使用 size 来模拟重复掷骰子的分布。首先将掷骰子的次数重复两次,为了获得代表性分布,进行10000次这样的重复投掷,使用 .mean() ...

我怀疑np.tile实际上平铺了相同的dict对象(在本例中是empty_ind)。因此，当您向pop[i, 0]['X']...

np.random.randint results in ValueError when specifying arguments that overflow int32 on Windows. I've seen some related discussions around the platform dependent default int behavior (#9464, #12332, #16535). If this classifies as a dupl...
Participants ages 13–17 years old were enrolled in three mutually exclusive groups: (1) teens who had attempted suicide duirng the past 30 days who had never engaged in NSSI (n ¼ 36) (2) teens meeting the DSM- V criteria for NSSI including 45 episodes of NSSI during the past year...
