ImportError: No module named matlab.engine

Hi,

I could not seem to import matlab.engine in python in my Ubuntu 15 as shown in the following figure:

The MATLAB Engine API for Python has been successfully installed following the instructions here http://au.mathworks.com/help/matlab/matlab_external/install-the-matlab-engine-for-python.html

Does anyone have a solution for this issue?

Answer 1

[KIEN NGUYEN]

This installation command, other than the original one, has worked for me: python setup.py build --build-base=$(mktemp -d) install

[Robert Snoeberger]

Can you import just matlab?

 >>> import matlab

Thanks!

Having the same problem - I can import matlab but once I try to import matlab.engine it says matlab is not a package.

[Nicolás Ugrinovic]

nice, thanks!

Anaconda may not work as MATLAB Engine API for Python supports CPython only:

http://www.mathworks.com/help/matlab/matlab-engine-for-python.html

Another issue to consider is whether your Python version support wide-Unicode:

http://www.mathworks.com/help/matlab/matlab_external/system-requirements-for-matlab-engine-for-python.html#buijf0m

Following code can be used to check it supports wide Unicode or not:

 >>> import sys
 >>> if sys.maxunicode > 65535:
 ...     print 'wide-unicde' 
 ... else:
 ...     print 'narrow-unicode'

I had the same issue with mine. I am running Ubuntu 16.04 and Python 3.6 on Pycharm, and Matlab 2018a. After installing Matlab Python API as given on http://au.mathworks.com/help/matlab/matlab_external/install-the-matlab-engine-for-python.html

it creates a folder structures like:

<installation-dir>/matlab/engine/

and

<installation-dir>/lib/ and <installation-dir>/lib.linux-x86-64-2.7/

or something like that. After I copied these directories into my Python project root they started working and I was able to import matlab.engine(). In Pycharm you can add source folders paths to your project; you can try something similar.

[Hongbin Liu]

Thank you for the answers. I would like to know what the Python project root is.

[Anshul Joshi]

I mean the folder within which your virtual environment is created. E.g.

/home/Folder1/venv,

then

Folder1

is your python project root

[Hongbin Liu]

Nice. I have known the Python project root. Then, the folder structures like

installation-dir/matlab/engine/

should be coped into the Floder1. However, the Floder1 is not a writable file. Therefore, I do not know where the folder structures should be written into. I am just a Python beginner. It is appreciate for your help.

[Hongbin Liu]

I have addressed my problem. I found that the Python could not find the Matlab module because my computer had two Python versions. Therefore, I pointed out the Python version when the API was installed, i.e. the installing code was changed as

python3 setup.py install

Best regards and thanks again.

I had same issue. I was trying it on Spyder but it didn't work. I rhen shifted to Pycharm and the error was gone. I guess there is some issue with Anaconda-Spyder.

Cannot get this to work, could you explain what you did in pycharm?
