<p><strong>我发布了这个问题,询问如何在Windows 10上获取CPU和GPU温度:<a href="https://stackoverflow.com/questions/62617789/get-cpu-and-gpu-temp-using-python-windows">Get CPU and GPU Temp using Python Windows</a>。对于这个问题,我没有包括不允许管理员访问的限制(至少在我第一次发布答案时是这样,之后的一段时间也是这样)。然后我修改了我的问题,使需要管理员访问的答案无效(这是当时唯一有效的答案)。一个mod回滚到我的问题的前一个版本,并要求我发布一个新问题,所以我已经这样做了。</strong></p>
<p>我想知道是否有办法在python中获得CPU和GPU的温度。我已经为Linux找到了一种方法(使用<a href="https://psutil.readthedocs.io/en/latest/index.html?highlight=temperature#psutil.sensors_temperatures" rel="nofollow noreferrer">^{<cd1>}</a>),我想为Windows找到一种方法</p>
<p>信息:<br/>
操作系统:Windows 10<br/>
Python:Python3.8.3<strong>64位(因此没有32位DLL)</p>
