Multiple GPU support

[v1ckxy]

Hello!
I've been looking around github and haven't found it... so I'm posting the question here.
Is there any way to configure a theme to display multiple GPUs /* or to specify a specific gpu */?

I've looked at the code (sensors_librehardwaremonitor.py and sensors_python.py) and it's not clear to me how to specify a specific card.

The system where I plan to use the display has 2 (and soon 3) NV cards and 1 integrated AMD.

Regards and thank you for this great work.

Hello @v1ckxy!
For now the program has not been developed to support multiple GPUs 😞
This doesn't mean it's impossible though! But it needs big changes on sensors_librehardwaremonitor.py / sensors_python.py and also on the theme parser to be able to specify multiple GPUs inside theme.yaml files

To use a specific GPU:

For sensors_librehardwaremonitor.py:
At first start, the program will log all supported GPUs:
07/11/2023 19:46:08 [INFO] Found AMD GPU: Radeon ...
To use a specific GPU from the list, copy the GPU name then edit this line:

turing-smart-screen-python/library/sensors/sensors_librehardwaremonitor.py

Line 160 in d44505f

return gpu_to_use

to:
return "Radeon ..."

For sensors_python.py:
For Nvidia cards the program uses all available Nvidia cards sensors from GPUtil.getGPUs() and returns an average:

turing-smart-screen-python/library/sensors/sensors_python.py

Lines 139 to 149 in d44505f

	class GpuNvidia(sensors.Gpu):
	@staticmethod
	def stats() -> Tuple[float, float, float, float]: # load (%) / used mem (%) / used mem (Mb) / temp (°C)
	# Unlike other sensors, Nvidia GPU with GPUtil pulls in all the stats at once
	nvidia_gpus = GPUtil.getGPUs()
	try:
	memory_used_all = [item.memoryUsed for item in nvidia_gpus]
	memory_used_mb = sum(memory_used_all) / len(memory_used_all)
	except:
	memory_used_mb = math.nan

You would have to edit the code to use only the GPU you want from the GPUtil.getGPUs() method

Thanks! I will have a look at those parts of the code.

Maybe I can just implement a foreach somewhere and then throw GPU0, 1, 2...
