windows如何查看nvidia显卡（GPU）的利用率和温度

nvidia-smi

只要在文件夹C:Program FilesNVIDIA CorporationNVSMI里找到文件nvidia-smi.exe，把该文件拖到命令提示符窗口（win+R，再输入‘CMD’进入），就可以显示关于GPU的信息，如下图所示：

Windows 上不显示每个程序显存占用 N/A nvidia-smi

主要原因是这个功能在显卡显示画面时不能用Not available in WDDM driver model 

If you perform the following : nvidia-smi -q you will see the following:

Processes
        Process ID                  : 6564
            Type                    : C+G
            Name                    : C:Windowsexplorer.exe
            Used GPU Memory         : Not available in WDDM driver model

Not available in WDDM driver model => WDDM stand for Windows Display Driver Model. You can switch to TCC and obtain the information with the command: nvidia-smi -dm 1, however this operation can only performed if you do not have any display attached to the GPU. So… It’s mostly impossible…

By the way, don’t worry about a high memory usage, Tensorflow reserve as much GPU memory as it can to speed up its processes. If you prefer a finer grained control on the memory taken use the following (it may slow down a little bit your computations):

config = tf.ConfigProto()
config.gpu_options.allow_growth = True
sess = tf.Session(config=config)

You can create a dual boot on Ubuntu or just forget about this.
