Python Module Error on Linux

Question

I am using python 2.7 on Linux Mint 16. I am facing an error, if I run my IDE (tried it on Spyder and Pycharm) from a program launcher (eg. from the prompt at Alt F2 or an icon shortcut on my desktop) the modules do not load and I get the following error ``` File "/usr/local/lib/python2.7/dist-packages/gurobipy/__init__.py", line 1, in from .gurobipy import * ImportError: libgurobi56.so: cannot open shared object file: No such file or directory ``` However, if I run the program from the command line the modules load correctly and the program runs fine. I have only one installation each of the IDEs. The sys.path output from the two instances are as follows: sys.path output for Pycharm run from shortcut: ``` /home/XXXXXX/bin/pycharm-community-3.1.3/helpers/pydev', '/usr/local/lib/python2.7/dist-packages/pip-1.5.5-py2.7.egg', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-x86_64-linux-gnu', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/usr…

Accepted Answer

You don't set the path to the gurobipy.

Download then untar to `/opt`.

```
cd to `/opt/gurobi562/linux64` and run `python setup.py install`
```

Add following to `~/.bashrc`.

```
   export GUROBI_HOME="/opt/gurobi562/linux64"
   export PATH="${PATH}:${GUROBI_HOME}/bin"
   export LD_LIBRARY_PATH="${LD_LIBRARY_PATH}:${GUROBI_HOME}/lib"
```

From bash type `source ~/.bashrc`

start ipython shell and try `from gurobipy import *`, it should work fine, the only error it will give is about not having a licence if you have not downloaded and installed one from here

To set system wide access, first create

```
sudo gedit /etc/ld.so.conf.d/gurobi_pi.conf
```

Then add

```
/opt/gurobi562/linux64/lib
```

and save the file.

Then enter

```
sudo ldconfig
```

to update the libs across the system. You should have access to the shared libs in Pycharm.
