Can't find the vpsolver_scip.sh for SCIP optimizer

[jbsdadilet]

Hello, I have completed the following in Ubuntu: "sudo apt-get install make" "sudo apt-get install bash" "sudo apt-get install gcc" "sudo pip3 install pyvpsolver" However, running script suing SCIP optimizer providing me below error. Did I miss some steps of pyvpsolver on Ubuntu?

You need to have SCIP installed in the machine first. Go to: https://scipopt.org/#download and download scipoptsuite-8.0.1.tgz You can have an academic licensed version of that.

Compiling SCIP directly can be done as follows:

1) unpack the tarball "tar xvzf scipoptsuit-x.y.z.tgz"
2) change into the directory "cd scipoptsuit-x.y.z"
3) start compiling SCIP "make"
3) (recommended) check your SCIP installation "make test"
4) install the header, libraries, and binary, e.g.,
   "make install INSTALLDIR="/usr/local/"
