📄 Description

Description

Add Device.memory_temperature(), the equivalent of nvidia-smi --query-gpu=temperature.memory, implemented via the official NVML field NVML_FI_DEV_MEMORY_TEMP, and include it in device snapshots. Returns NA on GPUs that do not expose a memory temperature sensor through NVML.

No sudo, /dev/* access or kernel options are required.

Test

from nvitop import Device
print(Device(0).memory_temperature())

On an RTX 4090 (driver 580.167.08) this returns N/A, matching nvidia-smi.
