pynvml not support lookup process info

When I call nvmlDeviceGetGraphicsRunningProcesses, raise below exception.

So, I guess may be is the pynvml change something lead to this problem #72

[hstk30]

I guess maybe is Hanlp depends pynvml, I’m not sure.

@hstk30 That seems correct. It should never use pynvml as a dependency; actually this package should never have existed.
