Hello guys,

I tried to install Matlab engine for Python on Macbook M1.

But when I try to import matlab.engine, I met some errors.

Anyone know how to fix this error?

Thank you in advance.

import matlab.engine
ImportError:
dlopen(/Applications/MATLAB_R2022a.app/extern/engines/python/../../../extern/bin/maci64/matlabmultidimarrayforpython.cpython-39-darwin.so, 0x0002): 
tried: '/Applications/MATLAB_R2022a.app/extern/engines/python/../../../extern/bin/maci64/matlabmultidimarrayforpython.cpython-39-darwin.so' 
(mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64e')),

兄弟你这句话I am using the open beta of native implementation. 是说你是在用原生适配m1的matlab软件还是在说python啊，我是rosseta2转译的matlab，在命令行执行arch -x86_64 python3报arch: posix_spawnp: python3: Bad CPU type in executable

我用的m1适配的MATLAB. 然后我是用的这个方法，最后是能运行了。你可以试试，看能不能行

Python 安装matlab
1.install python 3.8 under -x86_64
arch -x86_64 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
alias ibrew="arch -x86_64 /usr/local/bin/brew"
ibrew install python@3.8
2. Open Matlab:
cd (fullfile(matlabroot,'extern','engines','python'))
system('/usr/local/opt/python@3.8/bin/python3.8 setup.py install')
3. Open VS code:
Set python interpreter:  /usr/local/opt/python@3.8/bin/python3.8

If you are using the MATLAB R2022a Native Apple Silicon Platform Open Beta, one of the limitations listed on that page is "MATLAB Engine API for Python is not available."
