About install issues (Patch & PySCIPOpt)

[sugyeong-jo]

Hello gasse,

I have been read your paper very impressively.
Currently, I am working on a task to solve the MILP problem of 100,000 by 100,000 sizes.
Many attempts have been made to adapt your model.
However, the following problems occurred.

My computer details are as follows.
-Linux 86X

1. patch issues

I had to patch after installing SCIP, but I couldn't patch because the scip/benders_default.o file was not found.

2. Install PySCIOpt
This also gave me the following error:

Probably, the problem occurred because the install did not work properly.
(I think it is an extension of the patch problem.)
As far as I know, pyscipopt is not needed on Linux.
Therefore, in the generating part, pysciopt was excluded from the utility, and it worked well. But in the second file, I need to use scip.Branchrule, which seems to be without pysciopt.

Sorry for asking too little of a problem.
Please answer if you are not very busy.
