Using from docplex.cp.model import CpoModel I have written a docplex code. Model defenition is as follows.

mdl = CpoModel(name="HouseBuilding")

But by the solve() function it is printing unnecessary output with the solution at last.

msol = mdl.solve(TimeLimit=10)

I believe it is printing below things .

solve status,
solver parameters,
solver information
output log

Sample output as follows.How should I avoid print these information but only the solution.

You only need set the log_output parameter to delete this unnecessary output

msol = mdl.solve(TimeLimit=10, log_output=False)

To print objetive value (aka solution):

print(msol.objective_value)

Finally, if you need to access the solution of your variables, you must iterare your Narray variable and use:

msol[var_name[(i, j, ... , etc. )]]))

I hope this answer will be helpful to you and sorry for my English.
