When I use gurobipy and Model constructor, there is an error which tells me that there is no my user name.

(I'll describe the error and my input strings in ipython.)

 

How should I do to use gurobipy?

In [1]: from gurobipy import Model

  Hi,

  Your user name is not detected. What operating system are you using? It looks like a Linux/UNIX but what's uncommon is that your home directory is in another subdirectory "cl". Can you please run "whoami" and "uname -a" and post the results here?

  Thanks,
  Matthias

  Thank you for the fast reply.

   

  I'm running on Ubuntu 16.04.6 LTS (GNU/Linux 4.4.0-165-generic x86_64).

  Yes, my home directory is "/home/cl/takayoshi-s".

  (Subdirectories under "/home" is shared between multiple servers by NFS.)

   

  ---- Result of "whoami" and "uname -a" -----

  takayoshi-s@pine42:~$ whoami

  takayoshi-s

  takayoshi-s@pine42:~$ uname -a

  Linux pine42.naist.jp 4.4.0-165-generic #193-Ubuntu SMP Tue Sep 17 17:42:52 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

  Hi Takayoshi,

  This is all looking fine so far. Can you please post the output of grbprobe as well?

  Thanks,
  Matthias

  This is the output of grbprobe.

  Can you successfully run "gurobi_cl --license"?

  Cheers,
  Matthias

  At first, there is a problem with running "gurobi_cl --license", so I run "chmod +x" for licence file.

  Then, the problem is solved. 

  After that, I reinstalled gurobipy for a new python virtual environment.

  However, the same problem(No user name & "User name mismatch" error) occurred again.

   

  ----output of "gurobi_cl --license"---

  (tax-org) takayoshi-s@pine42:~$ gurobi_cl --license

  Hi Takayoshi - 

  Can you try running whoami and uname -a from within your Jupyter notebook?

  ! whoami
  ! uname -a

  Thanks, Gwyneth

  Hi Gwyneth, thank you for your advice.

  I tried both commands on Jupyter and IPython.
