I'm trying to use (and therefore install) an optimization package called mosek and more specifically to use it with python on a jupyter notebook.

It's a commercial package but since I'm working in academia, I have a free license.

This issue has been edited thanks to Paul insights.

My goal is to be able to use mosek in python 3.5 through jupyter.

1° My issue:

When I run the following line of code in jupyter notebook : 

import mosek.fusion

I have the following error: 

import mosek.fusion ---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-9-81543b63d59f> in <module>()
----> 1 import mosek.fusion

ImportError: No module named 'mosek.fusion'

2° What I did :

I first downloaded and installed mosek. I also added my licence in my folder mosek. (I did all the steps described here : http://docs.mosek.com/7.1/toolsinstall/Linux_UNIX_installation_instructions.html and added my academical license as well).

I then tried to run the line of code: import mosek.fusion which gave an error. I then tried to run:

import mosek

then I had no error. My conclusion is that mosek is (now, thanks to Paul), properly installed but that fusion module is missing.

I also search for any fusion file or folder in my mosek folder. I did not find any.

Is there a way to get this module fusion from mosek, and even better, is there a way to make it work?

Thank you all!

E.

I believe that it installed it to your .local because you installed with the --user flag. In other words:

python setup.py install --user

Trying running the install without the --user flag. That should install it in your conda environment.

But I'm not sure that is your import problem. Perhaps the fusion module doesn't exist. Try ls-ing what is in this folder /home/edwin/.local/lib/python3.5/site-packages/mosek/. Maybe try from mosek import fusion.

    You are right, I install it again without --user and it installs it in my conda environment. I then tried your advice from mosek import fusion but I had exactly the same error as before. I then try to look for a fusion file or folder in my mosek folder within conda, and there is no such file/folder... Any idea how I can get fusion ? I guess I will edit my question so that it gets more specific. Thank for your help, it helped me targeting my real issue. – probaPerception Apr 27 '16 at 15:50

Fusion is not yet available for Python3. It will in the next major release, i.e. MOSEK 8.

The easiest way to install Mosek (for using from Python) is to use the pip installer:

pip install git+http://github.com/MOSEK/Mosek.pip@v7.0.0#egg=mosek

You may also want to set the environement variable for the Mosek lisence explicitly, e.g.

os.environ.setdefault("MOSEKLM_LICENSE_FILE", license) where license is a server address or a file location.

However, Mosek Fusion is not yet available for Python 3

  • Thank you but I found a way to use Mosek and fusion with Python. I needed to use Python 2 instead of Python 3. – probaPerception May 15 '16 at 21:30
  • Installing via pip doesn't care whether you use Python 2 or Python 3. This is just a tool to make the install simpler and automated (maybe you have a testserver etc). – tschm May 17 '16 at 07:52

Keep on the MOSEK website. Version 8(beta) soon to be released will support Python 3.5. Also full Anaconda support will soon be available.
