我正在尝试以编程方式获取 mac OSX 平台上的 GPU 温度
我尝试在 google 上搜索解决方案，但找不到，我只能找到 CPU 温度和 GPU 使用百分比。
是否有一些 API 或库允许检索传感器数据？
有人可以告诉我从哪里开始吗？ 或者提供一些例子？

Q: How can I get information on GPU temperature from my application? On Microsoft Windows platforms, NVIDIA's NVAPI gives access to GPU temperature and many other low-level GPU functions
Under Linux, the "nvidia-smi" utility, which is included with the standard driver install, also displays GPU temperature for all installed devices.

在进一步查看基于 linux 的系统提供的“nvidia-smi”实用程序时，我发现他们提供了基于 C 的 API 来获取 GPU 温度。
https://developer.nvidia.com/nvidia-management-library-nvml https://developer.nvidia.com/nvidia-system-management-interface
从手册中，我可以看到下面的 API 可以用来找出哪些是由“nvidia-smi”提供的:
7.9.2.8 nvmlReturn_t DECLDIR nvmlUnitGetTemperature (nvmlUnit_t unit, unsigned int type, unsigned
int temp)
Retrieves the temperature readings for the unit, in degrees C.
For S-class products.
Depending on the product, readings may be available for intake (type=0), exhaust (type=1) and board (type=2).
Parameters:
unit The identifier of the target unit
type The type of reading to take
temp Reference in which to return the intake temperature
Returns:
• NVML_SUCCESS if temp has been populated
• NVML_ERROR_UNINITIALIZED if the library has not been successfully initialized
• NVML_ERROR_INVALID_ARGUMENT if unit or type is invalid or temp is NULL
• NVML_ERROR_NOT_SUPPORTED if this is not an S-class product
• NVML_ERROR_UNKNOWN on any unexpected error
希望这对您有用，这样您就可以实现您的要求。 “nvidia-smi”在内部使用上述 API 来找出用户获得的 GPU 温度。这是 NVIDIA 提供的命令行实用程序。
