No module named coin_backend

asked 2018-08-07 07:08:15 +0100

Please help me, When I run Present.sage file content as a new notebook on SageMath 8.1, an error message appears with the phrase "No module named coin_backend". Even though I installed the package cbc, it still remains a problem. So where is the problem? Can someone tell me how I could to add the module?

You need to run make after the installation of cbc or at least rebuild sagelib. The documentation on MILP solvers says to install cbc like this:

sage -i cbc sagelib
