<div dir="ltr" data-setdir="false">Hi Ambrose, thanks for your response. I missed that detail and made the change. I uninstalled the conda version of pyscipopt since it came with it's own version of scip. I reinstalled pyscipopt via pip and it now appears that pyscipopt is using the version of scip that I build from src. It runs normally with the optimize() function. </div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">However when I try with the concurrentopt, it segfaults and produces a core file. I'm not sure what to do next. </div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">-Hon Fai<br></div><div><br></div>
