Failed to start Nvidia GPU Exporter

[sangshuduo]

I downloaded the latest version 1.2.1 and installed it on my Ubuntu 20.04. I followed the INSTALL instruction and run it as a systemd service. Now I see the service always failed.

$ sudo systemctl status nvidia_gpu_expoter.service
● nvidia_gpu_expoter.service - Nvidia GPU Exporter

I can run it from the terminal and be able to see the metrics output via localhost:9835.

$ sudo nvidia_gpu_exporter

ts=2024-11-05T02:38:09.902Z caller=tls_config.go:316 level=info msg="TLS is disabled." http2=false address=[::]:9835

Anybody please point out what I did wrong. Thanks.
