Need help with getting AMD GPU Power for use on CachyOS

[wonglc82-cmyk]

I tried adding this to custom_sensor.py to show AMD GPU Power on my 3.5" Turing screen, but seem to be getting errors. I saw a discussion with regards to Nvidia and Librehardware monitor, but as i understand it, Arch Linux would need to use pyamdgpuinfo instead. Could I get some help? Thank you!

import math
import logging
import pyamdgpuinfo
from library.sensors.sensors_custom_interface import CustomDataSource

logger = logging.getLogger(name)

class AMDGPUPower(CustomDataSource):
def init(self):
super().init()
# Initialise and detect the first available AMD GPU
try:
if pyamdgpuinfo.detect_gpus() > 0:
self.gpu = pyamdgpuinfo.get_gpu(0)
else:
self.gpu = None
logger.error("No AMD GPU detected via pyamdgpuinfo.")
except Exception as e:
self.gpu = None
logger.error(f"Failed to initialise pyamdgpuinfo: {e}")

def as_numeric(self) -> float:
    if not self.gpu:
        return math.nan
    try:
        # Query power usage in Watts
        return float(self.gpu.query_power())
    except Exception as e:
        logger.error(f"GPU Power cannot be read: {e}")
        return math.nan

def as_string(self) -> str:
    val = self.as_numeric()
    if math.isnan(val):
        return "N/A"
    return f"{int(val):>3} W"

The error I'm getting is;
