GPU Memory Usage
列显示每个单个进程的N/A
.另外,列出的过程比我在Internet上大多数示例中发现的过程要多得多.可能是什么原因?
The column GPU Memory Usage
shows N/A
for every single process. Also, there are a lot more processes listed than I found for most examples on the Internet. What could be the reason for this?
我正在运行ASUS的Nvidia GTX 1070,我的操作系统是Windows 10 Pro.
I am running a Nvidia GTX 1070 by ASUS, my OS is Windows 10 Pro.
推荐答案
如果执行以下操作:nvidia-smi -q
,您将看到以下内容:
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
在WDDM驱动程序模型中不可用=> WDDM代表 Windows显示驱动程序模型.您可以切换到TCC并使用以下命令获取信息:nvidia-smi -dm 1
,但是仅当您未在GPU上连接任何显示器时,才能执行此操作.所以...这几乎是不可能的...
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...
顺便说一句,不用担心内存使用率高,Tensorflow会保留尽可能多的GPU内存,以加快处理速度.如果您希望对所使用的内存进行更细粒度的控制,请使用以下命令(它可能会减慢您的计算速度):
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)
您可以在Ubuntu上创建双重启动,也可以忽略它.
You can create a dual boot on Ubuntu or just forget about this.
