AttributeError: module 'prometheus_client' has no attribute 'core'

[phpbg]

Any clue on this error? Change in prometheus API?

File "/home/sam/.local/lib/python3.6/site-packages/igd_exporter/igd.py", line 169, in collect
    g = prometheus_client.core.CounterMetricFamily(metric.name, metric.desc, labels=['udn'])
AttributeError: module 'prometheus_client' has no attribute 'core'

[phpbg]

NB: I fixed it locally with import prometheus_client.core instead of import prometheus_client

Not a python dev, so not sure what happens here...

With prometheus-client 0.14.1 I don't have to refer to prometheus_client.core...
