ImportError: No module named 'matlab' , DLL load failed

>>

While starting Matlab API for Python after providing the command import matlab.engine it gives me an error: ImportError: No module named 'matlab' Although the installation of python in matlab api was succesfull , there is no module named matlab in python. Can anyone help me? Thank You!

My first guess after seeing an import error that says, "No module named..." is that the module isn't installed. It would be helpful if you could provide more information about your statement that the installation of python in matlab api was successful. What command did you run? What was the output?

I ran

cd "matlabroot\extern\engines\python"
python setup.py install

which was succesfull. Then I tried pyversion and it showed

         version: '3.4'
      executable: 'C:\Python34\pythonw.exe'
         library: 'C:\Windows\system32\python34.dll'
            home: 'C:\Python34'
        isloaded: 1

then I opened the same python and tried to run import matlab.engine but it threw the error.

is there a way to install the module?

[Robert Snoeberger]

Ok, this doesn't look like an installation issue, since the module that cannot be imported is 'matlabengineforpython3_4'. The issue is the message that says "DLL load failed." There is probably a DLL version conflict. What other modules are imported in your call_matlab.py script?

[sushmita das]

None.I was just trying with the example provided at mathworks first.

import matlab.engine
future = matlab.engine.connect_matlab(async=True)
eng = future.result()
eng.sqrt(4.0)

I get this error when I try to just import matlab.

This is just an observation. In your original question you used "python". Then, in your latest comment you used "python.exe" that appears to be installed in "C:\Program Files\MATLAB|R2016a\extern\engines\python\Python34\". Are you using two different Python installations? That could explain the "No module named 'matlab'" error. You didn't install matlab.engine in the "C:\Program Files\MATLAB|R2016a\extern\engines\python\Python34\" installation.

[sushmita das]

No actually I am using "C:\Program Files\MATLAB|R2016a\extern\engines\python\Python34\" . Do I need to install matlab.engine in Python34 as well? Why is it required to install matlab.engine inside matlab?
