Infiniband-exporter service failed

Hello, I’ve installed and registered with systemd the Infiniband-exporter, but am running into the below error. /usr/local/bin/infiniband-exporter does exist, tho it is a .py file. I tried changing the
ExecStart line to ExecStart=/usr/local/bin/, but got

Apr 07 16:22:57 systemd[31883]: Failed at step EXEC spawning /usr/local/bin/ Permission denied
– Subject: Process /usr/local/bin/ could not be executed

It was owned by prometheus, but I chown’d to root, made no difference. Can anyone help?

Exporter obtained here:
