Fail to start matlab engine in python 2022b

Show older comments
I use MacBook Pro M1 chip with macOS13 and Python version is 3.9.13.
I installed the Matlab R2022b and followed the document to install engine API via pip with code :
python -m pip install matlabengine
However, when I call matlab engine, it is failed with the output
raise RuntimeError("Could not find directory: {0}".format(engine_dir))
RuntimeError: Could not find directory: /Applications/MATLAB_R2022b.app/extern/engines/python/dist/matlab/engine/maca64
I find the directory that I can only find maci64.
May I know how could I start matlab.engine in Python?

Why does matlab make it so hard to use jupyter. It is as if they dont want us using matlab with jupyter.

I think it is a M1 chip issue because I have the following directory: /Applications/MATLAB_R2022b.app/extern/engines/python/dist/matlab/engine/maci64
and
/Applications/MATLAB_R2022b.app/extern/engines/python/dist/matlab/engine/maca64
is what the script is looking for.

Could you check the default install location of MATLAB? This can be done by going into the MATLAB Command Window and calling :
matlabroot
By default, you will find MATLAB installed at the following location
/Applications/MATLAB_R2022b.app
When MATLAB is not installed in the default location, the bin/architecture directory within the MATLAB root directory must be added to an environment variable. The path can be added to the environment variable within the shell startup configuration file:
# in .bashrc
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:<matlabroot>/bin/glnxa64
Could you try these steps to see if the error still persists?

My MATLAB runtime root is at /usr/local/MATLAB_Runtime/R2022b on a GUI-less server Ubuntu 20.04 installation, so I checked
echo $LD_LIBRARY_PATH
And got nothing (it's not set) - am I required to install something else before R2022b to get this to work?
Then, I set the variable:
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/MATLAB_Runtime/R2022b/glnxa64
Still got the following error with pip install:
RuntimeError: MATLAB R2022b installation not found. Install to default location, or add <matlabroot>/bin/glnxa64 to LD_LIBRARY_PATH, where <matlabroot> is the root of a MATLAB R2022b installation.

Hi,
I am having more or les sthe same problem with 2023a version. When I try:
python -m pip install .
in the correct folder, I get the error:
error: MATLAB installation in /Applications/MATLAB_R2023a.app/extern/engines/python/../../../bin is maci64, but Python interpreter is maca64. Reinstall MATLAB or use a different Python interpreter.
And when I do:
python -m pip install matlabengine
I get
RuntimeError: MATLAB R2022b installation not found. Install to default location, or add <matlabroot>/bin/maca64 to DYLD_LIBRARY_PATH, where <matlabroot> is the root of a MATLAB R2022b installation.
which shouldn't be because I am using 2023a, so no 2022b installation...
Any idea of how to solve this weird problem?
cheers

Hi Gustav,
could you provide more details on which command you used to install the matlab engine using conda?

Hi, I had the same problem. The issue is not related to matlab but to Anaconda's installation. In my case, I didn't have the latest version which is now compatible with Apple's M processors. Uninstalling conda and updating to the latest version solved all the issues.
Good Luck!
