class GenericEncoder(json.JSONEncoder):

    import numpy 

    def default(self, obj):  

        if isinstance(obj, numpy.generic):

            return numpy.asscalar(obj) 

        elif isinstance(obj, datetime.datetime):  

            return obj.strftime('%Y-%m-%d %H:%M:%S') 

        else:  

            return json.JSONEncoder.default(self, obj)
