GRBModel.sync()

Wait for a previous asynchronous optimization call to complete.

Callingoptimizeasyncreturns control to the calling routine immediately. The caller can perform other computations while optimization proceeds, and can check on the progress of the optimization by querying various model attributes. Thesynccall forces the calling program to wait until the asynchronous optimization call completes. Youmustcallsyncbefore the corresponding model object is deleted.

Thesynccall throws an exception if the optimization itself ran into any problems. In other words, exceptions thrown by this method are those thatoptimizeitself would have thrown, had the original method not been asynchronous.

Note that you need to callsync即使你知道the asynchronous optimization has already completed.
