Re: cvxopt.glpk is not installed

The GLPK interface is not enabled by default, so you need to edit the setup script to compile CVXOPT with GLPK. Change the line "BUILD_GLPK = 0" in setup.py to "BUILD_GLPK = 1". Note that you will need the GLPK library and and header files in order to compile CVXOPT with the GLPK interface.

Hello,

I got this error while running my python project: 

File "C:\Python27\lib\site-packages\cvxopt\coneprog.py", line 2822, in lp
    except ImportError: raise ValueError("invalid option "\
ValueError: invalid option (solver = 'glpk'): cvxopt.glpk is not installed

Note that i already install the cvxopt module correctly.

Any idea?

Thanks.

You need to install GLPK separately. GLPK is available from here: http://www.gnu.org/software/glpk/

Note that CVXOPT 1.1.6 is compatible with GLPK version 4.48 and older versions.

Hi,

I am having trouble in getting my python 2.6 code to work when using cvxopt solver glpk

I downloded glpk for windows (4.52), and changed the setup.py to have build_glpk option as 1

Still does not work.

Please advise.

Thanks

You may follow the instructions in http://abel.ee.ucla.edu/cvxopt/install/. I've tried on Python 2.7. But I'm not sure if it will work as well for 2.6.

Good luck,
