IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.

We have compiled some common reasons and troubleshooting tips at:

Please note and check the following:

• The Python version is: Python3.12 from "D:\dev\python.exe"
• The NumPy version is: "2.1.3"

and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.

Original error was: No module named 'numpy._core._multiarray_umath'

The above exception was the direct cause of the following exception:

这个问题出现的原因是由于在导入numpy库时出现了错误。其中，主要的错误是由于缺少名为`numpy._core._multiarray_umath`的模块。 可能的原因包括：

1. Python或NumPy版本不匹配，比如可能的Python版本为3.12，但是NumPy版本为2.1.3。
2. 安装的NumPy库可能出现了问题。
3. 在导入numpy时尝试从源目录中导入，而不是从安装目录中导入。 解决方法包括：
4. 确保Python和NumPy的版本匹配并且正确安装。
5. 可以尝试重新安装NumPy库或者更新NumPy库。
6. 确保在导入numpy时，不要从源代码目录中导入，可以在其他地方启动Python解释器。 以下是可能的Python代码，用于重新安装或更新NumPy库：

pip install --upgrade numpy
