[英]How to get current CPU, GPU and RAM usage of a particular program in Python?
I have written a python program to detect faces of a video input (webcam) using Haar Cascade. 我编写了一个python程序来检测使用Haar Cascade的视频输入(网络摄像头)的面部。 I would like to know how much CPU, GPU and RAM are being utilized by this specific program and not the overall CPU, GPU, RAM usage.
我想知道这个特定程序使用了多少CPU,GPU和RAM,而不是整体CPU,GPU,RAM的使用情况。
I came across psutil package ( https://pypi.org/project/psutil/ ) which enables to profile system resources being used but I could not manage to get system resources being used by a specific program. 我遇到了psutil包( https://pypi.org/project/psutil/ ),它可以分析正在使用的系统资源,但我无法设法让特定程序使用系统资源。 How can I achieve that?
我怎样才能做到这一点?
I have also seen this How to get current CPU and RAM usage in Python? 我也看过这个如何在Python中获取当前的CPU和RAM使用率? but its not what I want.
但它不是我想要的。
My python code as follows: 我的python代码如下:
def main():
#Get current Process ID
pid = os.getpid()
#Get resources used by current process
p = psutil.Process(pid)
with p.oneshot():
cpu_percent = p.cpu_percent()
# Get Memory and GPU usage of this PID as well
You can get CPU/RAM metrics (not GPU) for a particular process given its PID: 在给定PID的情况下,您可以获得特定进程的CPU / RAM指标(不是GPU):
import psutil
psutil.Process(1234).cpu_percent()
psutil.Process(1234).memory_info()
