python - (mach-o 文件，但它是一个不兼容的架构(有 'arm64' ，需要 'x86_64' ))

Question

我在 Macbook Air M1 上运行 .py 文件时遇到问题:

[Running] python3 -u "/Users/kaiyuwei/Documents/graduation project/metaheuristics/run_CRO.py"
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: Python3.8 from "/Library/Developer/CommandLineTools/usr/bin/python3"
  * The NumPy version is: "1.23.1"

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

Original error was: dlopen(/Users/kaiyuwei/Library/Python/3.8/lib/python/site-packages/numpy/core/_multiarray_umath.cpython-38-darwin.so, 0x0002): tried: '/Users/kaiyuwei/Library/Python/3.8/lib/python/site-packages/numpy/core/_multiarray_umath.cpython-38-darwin.so' (mach-o file, but is an incompatible architecture (have 'arm64', need 'x86_64'))


[Done] exited with code=1 in 0.055 seconds

我认为原因是我正在为'x86_64'使用numpy包，所以我尝试使用pip install numpy --upgrade来升级numpy，但我得到了这样的输出:

Requirement already satisfied: numpy in /Users/kaiyuwei/Library/Python/3.8/lib/python/site-packages (1.23.1)

我也试过 python3 -m pip install --upgrade pip 来升级 python，但还是；

Requirement already satisfied: pip in /Users/kaiyuwei/Library/Python/3.8/lib/python/site-packages (22.1.2)

谁能帮帮我？

我通过简单地卸载 numpy 包解决了这个问题:

pip3 uninstall numpy

并重新安装它:

pip3 install numpy
