removing 'build/lib.linux-x86_64-2.7' (and everything under it)

'build/bdist.linux-x86_64' does not exist -- can't clean it

'build/scripts-2.7' does not exist -- can't clean it

removing 'build'

I think it's caused by lack of dependence.

Hi,

These messages don't necessary mean that the installation failed. What happens when you try to run on of our python examples? For example: mip1.py

You can find it in the Gurobi installation directory here: 

linux64/examples/python/mip1.py 

Also please note that we release Gurobi 7.5.1 last week. We recommend an upgrade to that version.

Best regards, 

Sonja

Hi Dr. Sonia,

mip1.py outcame with:

oliverjia@debian:~/opt/gurobi751/linux64$ python examples/python/mip1.py
Traceback (most recent call last):
  File "examples/python/mip1.py", line 13, in <module>
    from gurobipy import *
  File "/usr/local/lib/python2.7/dist-packages/gurobipy/__init__.py", line 1, in <module>
    from .gurobipy import *
ImportError: /usr/local/lib/python2.7/dist-packages/gurobipy/gurobipy.so: file too short

I think it's still a installation fails problem.

Thanks for your help.

Best,

Oliver

I had the same installation issue and it said "removing build". Tried running the mip1.py file and got this error:

 Traceback (most recent call last):

  File "C:\gurobi751\win32\examples\python\mip1.py", line 13, in <module>

    from gurobipy import *

  File "C:\Users\hp\AppData\Local\Programs\Python\Python36-32\lib\site-packages\gurobipy\__init__.py", line 1, in <module>

    from .gurobipy import *

ImportError: DLL load failed: %1 is not a valid Win32 application.

>>> 

Has it not been installed properly? I even tried 

>python setup.py install 

on cmd

Hi,

Did you get exactly this message:
build/bdist.linux-x86_64' does not exist

If so, it looks like you are installing a 64bit Gurobi.

From these messages it looks like you are installing a 32bit Gurobi:

> raceback (most recent call last):
> File "C:\gurobi751\win32\examples\python\mip1.py", line 13, in <module>
> from gurobipy import *
> File "C:\Users\hp\AppData\Local\Programs\Python\Python36-32\lib\site-packages\gurobipy\__init__.py", line 1, in <module>
> from .gurobipy import *
> ImportError: DLL load failed: %1 is not a valid Win32 application.

Can you please check that you are installing a 32bit Gurobi into a 32bit Python?

Best regards,
Sonja

I have installed a 32 bit Gurobi into 32 bit Python. However, my system is 64 bit. Is that the problem?

Thanks

[Sonja Mars]

No, that should not be the problem, but why do you want to run a 32bit application on a 64bit system? Why not using a 64bit Python and a 64bit Gurobi?

Do you just have one Gurobi installation on your system? Or do you also have a 64bit version somewhere installed?

[Sowbhagya Suresh]

I installed a 32-bit python quite sometime back unknowingly and don't want to uninstall it as I will have to install all the packages again. Hence I installed 32-bit Gurobi as well.
