How to solve the 'waiting for other threads' problem?

[KelvinZhang99]

Hello. I am currently use pyoptinterafce and gurobi to run my model. For the same model setting, the barrier method sometimes gives me solution quickly. However, I also sometimes face 'waiting for other threads' issue, and the model cannot be solved. CHATGPT told me this might be because other algorithms were running concurrently but didn’t produce a result. want to know whether fixing the optimization method can solve this problem and how to fix it. Thank you very much.

You should ask for the technical support from Gurobi. This is clearly not the problem of PyOptInterface.
