ModuleNotFoundError：没有名为“numpy.core._multiarray_umath”的模块

Question

我有一个在 Mac 机器上运行的简单 python 程序。

import numpy as np


def main():
    print("np arr test")
    arr = np.array([1.0, 2.0, 3.0])
    print(arr)


if __name__ == "__main__":
    main()

我已验证通过 pip 正确安装了 numpy 库

pip3 list | grep numpy
msgpack-numpy                      0.4.4.3
numpy                              1.16.2
numpydoc                           0.8.0

运行程序时出现以下错误

Traceback (most recent call last):

During handling of the above exception, another exception occurred:

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:

    https://numpy.org/devdocs/user/troubleshooting-importerror.html

Please note and check the following:

  * The Python version is: Python3.6 from "/usr/local/bin/python3.6"
  * The NumPy version is: "1.18.4"

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'

你能帮我弄清楚我错过了什么吗？感谢您的回复！

注意：基于stack overflow post，我通过以下命令更新了 numpy

pip3 install numpy --upgrade

pip3 list | grep numpy
    msgpack-numpy                      0.4.4.3
    numpy                              1.21.2
    numpydoc                           0.8.0
    WARNING: You are using pip version 21.2.1; however, version 21.2.4 is available.

但我仍然看到错误消息

尝试卸载 numpy 并重新安装。
