NVIDIA-SMI, NVML, Power usage: [NOT SUPPORTED] - gpu

Question

I tried to get current power usage with the following command in Windows 10 x64:
nvidia-smi.exe --format=csv,noheader --query-gpu=power.draw
And got the next result:
[Not Supported]
I checked it on the GTX1050(notebook) video card.
Please also see the nvidia-smi output:
+-----------------------------------------------------------------------------+
| NVIDIA-SMI 382.05 Driver Version: 382.05 |
|-------------------------------+----------------------+----------------------+
| GPU Name TCC/WDDM | Bus-Id Disp.A | Volatile Uncorr. ECC |
| Fan Temp Perf Pwr:Usage/Cap| Memory-Usage | GPU-Util Compute M. |

| N/A 38C P8 N/A / N/A | 319MiB / 2048MiB | 0% Default |
+-------------------------------+----------------------+----------------------+
Also tried to get this info via
NVML library:
nvmlReturn_t result;
nvmlDevice_t device;
result = nvmlInit();
if (NVML_SUCCESS != result)
{
printf("Failed to initialize NVML: %s\n", nvmlErrorString(result));
return 1;
}
result = nvmlDeviceGetHandleByIndex(0, &device);
if (NVML_SUCCESS != result)
{
printf("Failed to get handle for device %i: %s\n", 0, nvmlErrorString(result));
}
unsigned int power_usage = 0;
result = nvmlDeviceGetPowerUsage(device, &power_usage);
printf(nvmlErrorString(result));
The output is the same:
Not Supported
First question: Is exist the way to get the power usage or other parameter from NVIDIA card which is not supported?
Please also see the Feature Matrix part in the old
manual
it contain the information about features supported NVIDIA cards. Second question: Is exist such docs about new video cards?

Answer 1

I had the same problem with NVIDIA GT1030. It seems that some features including the feature you mention is no longer supported by NVIDIA in newer drivers. I solved the problem by installing an older version. Try finding the first version of driver that included support for your GPU. Check this link.
