(mach-o file, but is an incompatible architecture (have 'arm64', need 'x86_64'))

I have a problem when I run a .py file on a Macbook Air M1:

[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

I think the reason is that I'm using the numpy package for 'x86_64', so I tried to use pip install numpy --upgrade to upgrade numpy, but I got output like:

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

I also tried python3 -m pip install --upgrade pip to upgrade python, but still;

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

Can anyone help me?

I faced the same error. Just uninstalled and reinstalled the corresponding libraries in the venv and the issue got resolved.

Example -

Error - tried: '/Users/xxxxx/.local/share/virtualenvs/yyyyyy-ken6_ahQ/lib/python3.12/site-packages/numpy/core/_multiarray_umath.cpython-312-darwin.so' (mach-o file, but is an incompatible architecture (have 'arm64', need 'x86_64'))

pip3 uninstall numpy

pip3 install numpy

If any version related error is given, install the version that is suggested in the error message

pip3 install numpy==<version_number>

Run your python file or package with arm64.

Example

arch -arm64 app-store-connect

I had this issue in pycharm executing tests.

The problem was the interpreter for the test case was set to the wrong one.

Going to edit configurations for the test case fixed it.

I had this issue and after uninstalling and reinstalling didn't work, I updated to Python 3.11 and it works perfectly now.

This worked for me -

ARCHFLAGS="-arch arm64" pip install numpy  --compile --no-cache-dir
