在没有管理员权限的情况下使用 Python 获取 CPU 和 GPU 温度 - Windows

Question

我发布了这个问题，询问如何在 Windows 10 上获取 CPU 和 GPU 温度： Get CPU and GPU Temp using Python Windows 。 对于那个问题，我没有包含没有管理员访问权限的限制（至少在我第一次发布答案时，以及之后的相当长一段时间）。 然后我修改了我的问题以使需要管理员访问权限的答案无效（这是当时唯一的有效答案）。 一个 mod 回滚到我问题的先前版本，并要求我发布一个新问题，所以我已经这样做了。

我想知道是否有办法在 python 中获取 CPU 和 GPU 温度。 我已经找到了一种适用于 Linux 的方法（使用psutil.sensors_temperature ），并且我想找到一种适用于 Windows 的方法。

信息：
操作系统：Windows 10
Python：Python 3.8.3 64 位（所以没有 32 位 DLL）

以下是我尝试过的一些东西：

当我尝试执行以下操作时，我得到 None （从这里 - https://stackoverflow.com/a/3264262/13710015 ）：

import wmi
w = wmi.WMI()
prin(w.Win32_TemperatureProbe()[0].CurrentReading)

当我尝试执行以下操作时，出现错误（来自此处 - https://stackoverflow.com/a/3264262/13710015 ）：

import wmi
w = wmi.WMI(namespace="root\wmi")
temperature_info = w.MSAcpi_ThermalZoneTemperature()[0]
print(temperature_info.CurrentTemperature)

错误：

我也很擅长将 C/C++ 扩展与 Python、便携式命令行应用程序（将与subprocess.Popen一起运行）、DLL 和命令（将与subprocess.Popen一起运行）一起使用。

不允许使用非便携式应用程序。

Answer 1

问题

非特权用户需要以安全的方式访问只有特权用户才能使用的功能。

解决方案

创建一个服务器-客户端接口，其中的功能与实际系统分离，以防止出现安全问题（即：不要只是直接从客户端管道命令或选项供服务器执行）。

考虑为此服务器-客户端接口使用 gRPC。 如果您之前没有使用过 gRPC，这里有一个示例，说明这意味着什么：

创建一个temperature.proto ：

syntax = "proto3";

option java_multiple_files = true;
option java_package = "temperature";
option java_outer_classname = "TemperatureProto";
option objc_class_prefix = "TEMP";

package temperature;

service SystemTemperature {
  rpc GetTemperature (TemperatureRequest) returns (TemperatureReply) {}
}

message TemperatureRequest {
  string name = 1;
}

message TemperatureReply {
  string message = 1;
}

使用protobuf库中的protoc编译上述内容。

python -m grpc_tools.protoc --proto_path=. temperature.proto --python_out=. --grpc_python_out=.

这将生成一个名为temperature_pb2_grpc.py的文件，您将在其中定义 GetTemperature 的功能和响应，请注意，您可以根据从客户端传递的 TemperatureRequest 选项实现逻辑分支。

一旦完成简单的写和运行temperature_server.py从你的特权用户， temperature_client.py从非特权用户。

Answer 2

这会修改注册表，使用风险自负。

这适用于python：

• step1：关闭防病毒保护（我不知道如何通过自动化来做到这一点）
• 步骤 2：下载此存储库 - https://github.com/YashMakan/get_cpu_gpu_details
• 第三步：解压文件
• step4：打开app.py文件
• 步骤5：使用therm.py的完整路径更改变量“file”，例如 - C:\\\\...\\\\therm.py
• app.py ：运行app.py
• 第7步：您将获得详细信息
