Issue with 'SCIP: the parameter

[yzy1996]

Windows10

I have installed SCIP and pyscipopt successfully. But I met the problem which I can not find the answer. I wondered that whether I should install SoPlex separately.

I have solved this problem.

hello I have the same problem, can you give your solution?

[fserra]

the problem above was trying to set the parameter branching/vanillafullstrong/integralcands. However that parameter does not exist in scip 6.0.2
so you need to upgrade to scip 7

Agree with @fserra. And I solve this problem following the installation steps by learn2branch.

oh, but now the vanilla strong branching is included in scip7, so it should work out of the box
