Failed to run the bgp_peer example. #32
Description
I'm using my virtual machine, ubutnu20 LTS and player15.
I just download the z3, z3solver, and using my python 2.7 for the 2018's version.
then I download the requirements for synet-plus and the token.
when I run the bgp_peers, the things mostly seemed run well, but after printing the "Constraints adding time : xxxxx
Start Z3 check xxxx
Z3 check time: xxx
Setting the Var: xxx
Reading model time:xxxx
"
then it comes the error:
