Description
Added error catching for the static GPU memory information. Behavior only changes when the
pynvmlcall is not successful.Related Issue
#1037
Motivation and Context
For the NVIDIA DGX Spark, CodeCarbon trackers currently cannot be correctly initialized. When debugging into that, I noticed that calling
pynvml.nvmlDeviceGetMemoryInfoincodecarbon/core/gpu.pythrows anpynvml.NVMLError_NotSupported, probably due to the shared memore architecture of the NVIDIA Blackwell GPU (internally read as NVIDIA GB10).How Has This Been Tested?
Locally tested tracking functionality after the fix.
