Subject: [Ipopt] Error using Casadi + IPOPT + Pardiso
Message-ID: <0e503974cb2cd8e28a5b1df20f9c5a84@posgrad.ufsc.br>

Hello Everyone. 

I am having some trouble trying to use Casadi + IPOPT + Pardiso, didn't
find anything similar on the mailing list. 

I am solving an optimization problem using Casadi with my Python code, I
was originally using mumps, so it works well when I define:

opts = {'ipopt.print_level': 0, 'print_time': 0, 'ipopt.linear_solver':
'mumps'} 

When I change to:

opts = {'ipopt.print_level': 0, 'print_time': 0, 'ipopt.linear_solver':
'pardiso'} 

I get this error message: 

.../casadi/core/optistack_internal.cpp:997: Assertion
"return_success(accept_limit)" failed:
Solver failed. You may use opti.debug.value to investigate the latest
values of variables. return_status is 'Invalid_Option' 

If I use any non-existent name as 'roberto' for the linear solver I get
a different error, so I guess this is something related to the
configuration. 

I am using VSCode in Ubuntu, installed Atlas/lapack and Pardiso, then
./configure --with-pardiso and the make, everything went well. 

Any idea of what could be missing? 

Thanks in advance, 

Roberto Willoughby.

Hi,

if you do not set the Ipopt print_level to 0 you may see more 
information on why the option was found invalid.
But the --with-pardiso argument of configure should take the linker 
flags for Pardiso (probably just the path to the library) as value. Just 
saying --with-pardiso is probably not doing anything.
