python - Python 可见的弃用警告

Question

我正在尝试用 python 为经济学论文建立一个模型并计算函数:

elif wage_online == max(wages):
            # after going to online you get the highest wage after cost of education
            learning_benefit = int(np.int((1 + gamma_online_learning) * x[0]) * exp(np.int(bivariate_distribution[x[0] - 1, x[1] - 1])))
            social_benefit = int(((1 + gamma_online_social) * np.int(x[1])) * exp(np.int(bivariate_distribution[x[0] - 1, x[1] - 1])))
            sigma_social.append(social_benefit)
            sigma_learning.append(learning_benefit)

我收到以下错误

/Users/sa/Documents/Dissertation/first_defiation.py:160: VisibleDeprecationWarning: using a non-integer number instead of an integer will result in an error in the future
  learning_benefit = int(np.int((1 + gamma_online_learning) * x[0]) * exp(np.int(bivariate_distribution[x[0] - 1, x[1] - 1])))

我尝试通过将 exp 函数中的值包含为 np.int 来解决此问题，但无济于事。有谁知道警告来自哪个变量？

Answer 1

看起来您错过了方括号内需要 int 的地方:

social_benefit = (1 + gamma_online_social) * x[1] * exp(
    bivariate_distribution[int(x[0] - 1), int(x[1] - 1)]   # needed here for indexing
)

将来，您可以使用 warnings.filterwarnings('error') 来查找警告的准确回溯，这将指向您 __getitem__
