matlabmult​idimarrayf​orpython error

Hi,

I am struggling to use the MATLAB Engine API for Python.

For the installation I used the instructions here but modified it by running

python -m pip install . --prefix="path/to/conda/environment"

No error is reported so I think I installed it correctly but when I try:

import matlab.engine
eng = matlab.engine.start_matlab()
eng.sqrt(4.0)
eng.exit()

It gives the following error:

Traceback (most recent call last):
  File "/data/s3375218/AutoCD/autocd/test_matlab.py", line 1, in <module>
    import matlab.engine
  File "/data/s3375218/smac/lib/python3.9/site-packages/matlab/__init__.py", line 218, in <module>
    from matlabmultidimarrayforpython import double, single, uint8, int8, uint16, \
ModuleNotFoundError: No module named 'matlabmultidimarrayforpython'

I tried the following hacks posted here but I need to use this conda environment and I don't have enough space and I don't have root access in my remote directory to use CPython. Changing the "src/matlab/__init__.py" lead to import errors "mlarray" and "mlexceptions"

Any help will be appreciated.

Thanks!

The issue is that "mlarray" and "mlexceptions" is not located in the folders located in __arch.txt. To solve this, you need to edit "src/matlab/__ init __.py" :

+ sys.path.insert(0, os.path.dirname(os.path.dirname(engine_dir)))

+ from mlexceptions import ShareError, SizeError # and remove imports from mlarray.

If the problem persists after following these steps, please provide more details about the changes you made to the __init__.py file and any relevant error messages or traceback information you are encountering after above solution.
