ImportError: No module named gurobipy

[Maximilian Loosen]

Hi everyone,

I am using OSX Yosemite + the latest versions of Gurobi, Python 2.7.8 and Pycharm 3.4.

When I am using this configuration on my MacBook everything is working fine, but when I installed exactly the same applications on my Mac I get an ImportError: No module named gurobipy

Your help is greatly appreciated

It looks like gurobi is not properly installed. Maybe. 

Assuming you did “pip install coopr” and did not create a virtualized python environment…

Can you simple try to bring up the python interpreter and type “import gurobipy”? I suspect you should have the same problem there.

I know Gurobi is somewhat sensitive to the python version on MacOS. In any case, please report the results of the experiment indicated above.

Yeah I get the error when trying to import gurobipy.

When I type "import gurobipy" in the python shell the shell stops working and I get an "Python quit unexpectedly." error.

I just downloaded the Mac OSX gurobi installer and registered it with the license command.

What do you mean with "virtualized python environment" ?

Thank you for your help

Hi,

First of all please note that Gurobi Optimizer uses the default Apple Python (/usr/bin/python), currently in Yosemite version 2.7.6. We do not support other Python distributions including those from python.org.

Additionally, for installing Gurobi in your own Python distribution for example on a linux machine you need to follow the instructions here: http://www.gurobi.com/documentation/5.6/quick-start-guide/the_gurobi_python_interfac

Best regards,
Sonja

Pycharm installs another version of python.

Go to Preferences > Python Interpreter and Select Version 2.7.6

Have you remembered to install the Gurobi model into python (by running the setup.py script from the Gurobi install directory)?

I have Gurobi running fine with Python 2.7.8 under Mavericks (the python.org version), I made sure I followed these steps so that it was the proper version in /usr/bin/)

seems there are some issues with ending up with multiple python installs...
