<p>Hello Everyone.</p>
<p><br /></p>
<p>I am having some trouble trying to use Casadi + IPOPT + Pardiso, didn't find anything similar on the mailing list.</p>
<p>I am solving an optimization problem using Casadi with my Python code, I was originally using mumps, so it works well when I define:</p>
<div style="color: #cccccc; background-color: #1f1f1f; font-family: 'Droid Sans Mono', 'monospace', monospace; font-weight: normal; font-size: 14px; line-height: 19px; white-space: pre;">
<div><span style="color: #9cdcfe;">opts</span><span style="color: #cccccc;"> </span><span style="color: #d4d4d4;">=</span><span style="color: #cccccc;"> {</span><span style="color: #ce9178;">'ipopt.print_level'</span><span style="color: #cccccc;">: </span><span style="color: #b5cea8;">0</span><span style="color: #cccccc;">, </span><span style="color: #ce9178;">'print_time'</span><span style="color: #cccccc;">: </span><span style="color: #b5cea8;">0</span><span style="color: #cccccc;">, </span><span style="color: #ce9178;">'ipopt.linear_solver'</span><span style="color: #cccccc;">: </span><span style="color: #ce9178;">'mumps'</span><span style="color: #cccccc;">}</span></div>
</div>
<p>When I change to:</p>
<div style="color: #cccccc; background-color: #1f1f1f; font-family: 'Droid Sans Mono', 'monospace', monospace; font-weight: normal; font-size: 14px; line-height: 19px; white-space: pre;">
<div><span style="color: #9cdcfe;">opts</span><span style="color: #cccccc;"> </span><span style="color: #d4d4d4;">=</span><span style="color: #cccccc;"> {</span><span style="color: #ce9178;">'ipopt.print_level'</span><span style="color: #cccccc;">: </span><span style="color: #b5cea8;">0</span><span style="color: #cccccc;">, </span><span style="color: #ce9178;">'print_time'</span><span style="color: #cccccc;">: </span><span style="color: #b5cea8;">0</span><span style="color: #cccccc;">, </span><span style="color: #ce9178;">'ipopt.linear_solver'</span><span style="color: #cccccc;">: </span><span style="color: #ce9178;">'pardiso'</span><span style="color: #cccccc;">}</span></div>
</div>
<p>I get this error message:</p>
<p>.../casadi/core/optistack_internal.cpp:997: Assertion "return_success(accept_limit)" failed:<br />Solver failed. You may use opti.debug.value to investigate the latest values of variables. return_status is 'Invalid_Option'</p>
<p>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.</p>
<p>I am using VSCode in Ubuntu, installed Atlas/lapack and Pardiso, then ./configure --with-pardiso and the make, everything went well.</p>
<p><br /></p>
<p>Any idea of what could be missing?</p>
<p>Thanks in advance,</p>
<p>Roberto Willoughby.</p>
