windows如何查看nvidia顯卡（GPU）的利用率和溫度

nvidia-smi

只要在文件夾C:\Program Files\NVIDIA Corporation\NVSMI裏找到文件nvidia-smi.exe，把該文件拖到命令提示符窗口（win+R，再輸入‘CMD’進入），就能夠顯示關於GPU的信息，以下圖所示：

Windows 上不顯示每一個程序顯存佔用 N/A nvidia-smi

主要緣由是這個功能在顯卡顯示畫面時不能用

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:\Windows\explorer.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.
