No user name & "User name mismatch" error
AnsweredWhen 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?

I had the same issue on my machine, which was solved by changing my locale setting (i.e., LANG and LC_* environment variables); in particular, `export LC_ALL=C` fixed the issue and gurobi detected my username.

Hi Florian!
Did you try changing the LC_ALL environment variable?
export LC_ALL=C

I have the same problem, but I use windows. I'd be glad if any help can be provided.

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,

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.)

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

Hi Matthias,
This is the output of grbprobe.

Can you successfully run "gurobi_cl --license"?
Cheers,

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.

Hi Gwyneth, thank you for your advice.
I tried both commands on Jupyter and IPython.

Hey I might have the same issue,
I do have an academic license and I get the following error when executing my model:Set parameter Username
Error code: 10009. User name mismatch (licensed to 'florian', current user is '')When I execute
whoami
the result is
florian
Runninggrbprobe
results in

[...other infos]gurobi_cl --license
returns
Set parameter Username
Set parameter LogFile to value "gurobi.log"Failed to set up a license
Error 10009: User name mismatch (licensed to 'florian', current user is '')
How can I set the username correctly to be recognized by grbprobe and gurobi_cl?

Thanks for your quick response Matthias!
export LC_ALL=C
worked for me! For all IntelliJ Users: you might have to define the LC_ALL variable within the run configuration.
I'm sorry for the circumstances, I only double-checked that the code accesses the correct username but did not double-check the LC_ALL value.0 -

gurobipy.GurobiError: User name mismatch (licensed to 'root', current user is 'marcos')
It sounds like your named-user license was set up for the \(\texttt{root}\) user instead of \(\texttt{marcos}\). Did you use the \(\texttt{sudo}\) command when you initially ran \(\texttt{grbgetkey}\)? Could you try requesting another academic named-user license and running \(\texttt{grbgetkey}\) as user \(\texttt{marcos}\) (without \(\texttt{sudo}\))?

Hi
I have the same kind of issue but cannot fix it with your advices.
I still have to use gurobi 9.0.3. Running `grbgetkey` from gurobi 9.0.3 returns this
info : grbgetkey version 9.0.3, build v9.0.3rc0
info : Contacting Gurobi key server...
error : ERROR 101: Username field cannot be blank
With the Linux binary of gurobi 9.5.2 I can generate the license file, but cannot use it:
Error 10009: User name mismatch (licensed to 'XYZ', current user is '')0 -

Can you please upgrade to the latest version of Gurobi (11.0.2), then post the output of the following commands in the terminal? I'll assume you already set the \(\texttt{GUROBI_HOME}\), \(\texttt{PATH}\), and \(\texttt{LD_LIBRARY_PATH}\) environment variables appropriately. If not, please first follow the instructions for a "full installation" in the article How do I install Gurobi Optimizer?.
