No process and user information in output (for graphics application)

I have no process and user information while running gpustat with -cpu flags.

gpustat 0.4.0.dev
% python -m gpustat -cpu

nvidia-smi v384.59 shows processes as well. Here is XML dump from it: nvidia-smi_out_gtx750ti.xml.txt

I think I got it. It is documented feature:

This function returns information only about compute running processes (e.g. CUDA application which have active context). Any graphics applications (e.g. using OpenGL, DirectX) won’t be listed by this function.

https://docs.nvidia.com/deploy/nvml-api/group__nvmlDeviceQueries.html#group__nvmlDeviceQueries_1g46ceaea624d5c96e098e03c453419d68

I guess this is about CUDA applications - and I was running glxgears for testing. So I found another function in their API and did some weird patching like this:

diff --git a/gpustat.py b/gpustat.py
index 8b45fde..a5210e2 100755
--- a/gpustat.py

+                comp_processes = N.nvmlDeviceGetComputeRunningProcesses(handle)

                     # CPU percentage, create time etc.

And now I have this:

@wookayin Current master works as expected, thank you.
