ModuleNotFoundError: No module named 'prometheus_client'

Hello, I'm getting an error when attempting to start the infiniband exporter service:

Started Infiniband_exporter.
Aug 11 14:20:42 <nodename> python3[374627]: Traceback (most recent call last):

Aug 11 14:20:42 <nodename> systemd[1]: infiniband_exporter.service failed.

Is there a dependency that I am missing - CounterMetricFamily, GaugeMetricFamily ? If so, where do I get it?

i'm using v 0.0.4

Thanks

Hi,
This module currently need to be installed manually with pip3 install prometheus-client.

python2 support for this program was removed in the latest release, previously this was using python2-prometheus_client from epel to provide this module and there are no python3-prometheus_client available on Centos 7.

A small warning was placed in the README.md in this commit 20dcf98

The upstream module:
https://pypi.org/project/prometheus-client/

Hi,

you can also use Miniconda for resolving dependencies in Python.
It is a great tool. I just use the installer and then manage the dependencies.
With that you can also get different Python versions and environments running easily.

I have written some notes about that here.

The prometheus_client is also available there:

$ conda search prometheus
prometheus. Search: *prometheus*
