Problem with labels method on metrics objects

I am expecting to be able to set labels on a Counter like in the examples:

from prometheus_client import Counter
c = Counter('my_requests_total', 'HTTP Failures', ['method', 'endpoint'])
c.labels(method='get', endpoint='/').inc()

I am using prometheus-client (0.0.14) from PyPI.

$ python

>>> c = Counter('items_total', 'number of items total', registry=reg)
>>> c.labels(first=1, another=2).inc()
Traceback (most recent call last):

The Counter object does not seem to have a labels method attached to it. Perhaps some recent changes has affected the application of the decorator that applies it to the metrics? #99 kind of indicates this same problem but has words relating it to pushgateway.

you can try: g = Gauge(‘node_load5_norm’, ‘node_load5_norm’, [“host”], registry=registry) g.labels(hostname).set(value) push_to_gateway(gateway_uri, job=‘pushgateway’, registry=registry)

then: metric like this: node_load5_norm{‘host’=xx} 0.1
