ValueError: Duplicated timeseries in CollectorRegistry:

[Khayam Gondal]

Hi, I know this error means that there is a metric already with that name in the collection. Is there any way that I can get the already existing metric's object and use that?

For example, this is the syntax 

summary = prom.Summary('keras_predict', 'keras predictions')

I want to be able to do something like

summary = prom.get_metric_by_name('keras_predict')
