In Oython, Docplex reports BrokenPipeError and Invalid argument when solving a particularly large cp model
The model is solved fine, but when the model is relatively large (150,000 variables, 620,600 constraints), cp.solve() reports an error
In python, docplex reports BrokenPipeError and Invalid argument when solving a particularly large cp model
The model is solved fine, but when the model is relatively large (150,000 variables, 620,600 constraints), cp.solve() reports an error “0SError: [Errno 22] Invalid argument” in self.pout.write(frame) in the _write_message(self, cid, data=None) method.
Also there will be an error “BrokenPipeError: [Errno 32] Broken pipe”

Use ProgressListener with multiobjective in docplex (CPLEX)
I am translating an implementation of a gurobi model to cplex which uses multi-objective functionality and uses the following callbacks. The purpose of the callbacks is to extract the information from the optimization process as the different objectives are optimized.
