I am working on a non-linear network-optimization problem. When I run a large problem instance on the lab high-performance computers (imposing the time limit of 1 or 2 hours), those computers give me the output when the time is exhausted.
I wanted to use Google Collab to run the same code and to share it with my supervisors (they don't have Pyscipopt installed on their computers). However, when the problem size is small – all is good, but when the problem size is large, it says that the execution is completed (on the bottom of the screen) along with the time it took and a small red exclamation mark BUT it does not show any output for the large-size network optimization problems (neither it prints the solution nor it explains what is the reason/error of this behaviour).
Again, the same code works perfectly fine on high-performance computers, so I do not think there are any problems with syntax.
Please let me know if there are any solutions to the problem described.
Kind regards, Lidiia
I tried to change "None" in the hardware accelerator to GPU and CPU. I tried to proofread the code in order to find any mistakes. I tried to not leave the Google Collab to run the code at night (I read somewhere that kernel stops working if there is inactivity) so I tried to click on something there to prevent the execution from stopping. Nothing worked.
