异常发生在PyCharm

Question

当我尝试调试 PyCharm IDE 中的以下代码时，我得到 'NoneType' object is not callable'。在 Visual Studio 代码中调试时，或者在运行中调试代码时，我都没有得到相同的错误 Pycharm.

new_dataframe = dataframe.replace("\"", "", regex = True)

此代码片段也复制了错误：

import pandas

dataframe = pandas.DataFrame()
dataframe['PMES'] = ['No', None]

new_dataframe = dataframe.replace("\"", "", regex = True)

teste = ""

这是我在 Visual Studio 代码

中的 DataFrame（在 DataViewer 中看到的）

DataFrame in Visual Studio Code

这是PyCharm中的DataFrame。

DataFrame in PyCharm

在同一个项目中可视化的两个 DataFrame，具有相同的代码，错误仅发生在 PyCharm。

这是带有审查的完整 PyCharm 追溯。

Answer 1

这似乎是 known numpy bug #21008 with Python 3.10. There are plenty of complaints about this on the PyCharm boards too. The internal numpy discussion suggests that a fix is expected with numpy 1.22.4。在那之前，Python 3.9.12 似乎没有这个问题。
