Sklearn 在调试模式下的 roc_auc_score 错误但在正常运行时运行良好？

Question

我正在使用roc_auc_score来评估两个数组之间的 AUC，即真值和估计值。 当我在 PyCharms 上正常执行代码时，我的代码运行良好； 但是，当我使用调试模式时，会弹出以下奇怪的错误。 我尝试在roc_auc_score行之前暂停代码，并尝试仅使用带有 2 个小数组的调试控制台运行它。 同样的问题。 奇怪的是，使用普通的 Python 控制台一切都很好。 有任何想法吗？

Traceback (most recent call last):

    self.dtype = numeric.dtype(int_type)
TypeError: 'NoneType' object is not callable

During handling of the above exception, another exception occurred:

嗯......猜我只是在谷歌上搜索错误的东西：P

这似乎是 PyCharms 和 python 版本之间的问题（ https://youtrack.jetbrains.com/issue/PY-52137 ）。

从 Python 3.10.1 切换到 3.9 应该可以。
