    hi All,

    I have been using docplex for a while, but for some reason (recent update?) its logging behavior has changed recently:
    Whenever I call :
    from docplex.mp.model
    m = Model()
    .... # create my model
    m.solve()

    I get this type of UNDESIRED information :
    Notify start solve: engine_type=None, solve_details={
    "MODEL_DETAIL_INTEGER_VARS": 0,
    "MODEL_DETAIL_CONTINUOUS_VARS": 13,
    "MODEL_DETAIL_CONSTRAINTS": 11,
    "MODEL_DETAIL_BOOLEAN_VARS": 0,
    "MODEL_DETAIL_KPIS": "[]",
    "STAT.cplex.size.integerVariables": 0,
    "STAT.cplex.size.continousVariables": 13,
    "STAT.cplex.size.linearConstraints": 11,
    "STAT.cplex.size.booleanVariables": 0,
    "STAT.cplex.size.constraints": 11,
    "STAT.cplex.size.quadraticConstraints": 0,
    "STAT.cplex.size.variables": 13,
    "STAT.cplex.modelType": "LP",
    "MODEL_DETAIL_OBJECTIVE_SENSE": "minimize"
    }
    06/20 02:36:57 Notify end solve, status=JobSolveStatus.OPTIMAL_SOLUTION, solve_time=None
    ​
    This does not happen when printing to the console, but happens when using logging module instead of print (for other parts of my code).
    I tried several things like: m.solve(log_output=False) or m.logger.set_quiet() but nothing worked so far.
    So my question is how to avoid printing these solve details ?

    Thanks in advance for your help!

    Can you give more details how your run docplex (python interpreter, notebooks, Cloud pack for Data,...)? 
    Did you change the logging in any way (level for example?)?

    I am using PyCharm 2020.1.2, python 3.7, docplex 2.22.213, solve locally (I have the academic license).
    No I have not changed the logging in any way.
