  Hi Enis,

  There is no Gurobi GUI or IDE which you can execute. Gurobi is meant to be execute via the command line or to be called via a programming language API, e.g., the Python API. One way to test whether you have set up your license file and installed Gurobi correctly, please open a terminal window (on Mac: Command + Space, then type terminal and press Enter) and start

  najman@najman-xxxxx ~ % gurobi.sh

  This should provide an output similar to

  Python 3.7.4 (default, Aug 27 2019, 11:27:39) 
  [Clang 8.0.0 (clang-800.0.42.1)] on darwin
  Type "help", "copyright", "credits" or "license" for more information.
  Using license file /Users/najman/gurobi.lic
  Set parameter LogFile to value gurobi.log
  
  Gurobi Interactive Shell (mac64), Version 9.1.2
  Copyright (c) 2021, Gurobi Optimization, LLC
  Type "help()" for help
  
  gurobi> 

  This is the interactive Gurobi Python shell, which is not meant to be used for the solution of real problems but rather to play with smaller problem and a couple of commands. Typing \(\texttt{exit()}\) closes the Gurobi shell.

  Please have a look at our guide to Solving a Simple Model for more details and information.

  If you were not able to execute the above, please follow the Quick Start Guide for Mac to set up a license and install the Gurobi Optimizer.

  Best regards,
  Jaromił

  Hi Enis, 

  As discussed on the phone, and as my colleague Jaromił mentioned, Gurobi does not come with a Graphical User Interface. You mentioned that you only have to solve problems which are given as .LP files. For this you can either: 

  1. As described in Jaromił's message, open a Terminal and write 

  gurobi.sh  

  and once you see the screen shown in the message above, write the following commands:

  m = read('FILENAME') 
  m.optimize()

  where FILENAME is the name of the .LP file that you have to read (including the path to the file).

  or 

  2. Use the Gurobi Command-Line Tool as follows: from your Terminal, write

  gurobi_cl FILENAME

  (where FILENAME is the same as above).

  Best regards,

  Elisabeth

  Hello,

  I am having the same problem as Enis. I cannot find the Gurobi distribution directory or the examples. I know Gurobi does not have an IDE, but I guess I should be able to find the place where the software has been installed. Any help would be appreciated.

  Thanks

  Hi Diego,

  On a Mac, if Gurobi is installed correctly, you can try running the following in a terminal to help locate where Gurobi is installed:

  which gurobi_cl | xargs ls -l

  Typically it is installed here:

  /Library/gurobiXXX

  where XXX is the version number.
