Hi,

I am trying to run DeepStream using WSL2 but in the last step, when running sudo deepstream-test1-app /opt/nvidia/deepstream/deepstream-6.2/samples/streams/sample_720p.h264 It gives me the following error: image

How did you manage to put the GPU in the /dev/ directory of Ubuntu?

Thank you!

Hi,

simplest first: I would add './' before the app filename 

$sudo ./deepstream-test1-app /opt/nvidia/deepstream/deepstream-6.2/samples/streams/sample_720p.h264

otherwise:

a/ Did you use the provided example (wsl prep) to prepare your wsl instance ?

b/ Within your wsl instance, what do you see when you run the command ?

$nvidia-smi

Also, this output would be the default one if you did not fully compile/link the gst-nvinfer plugin. The way I'm testing this repo is:

$git clone https://github.com/sylvain-prevost/deepstream_wsl.git
$cd deepstream_wsl
$sudo cp -r sources/ /opt/nvidia/deepstream/deepstream-6.2

compile/link gst-nvinfer plugin

$cd /opt/nvidia/deepstream/deepstream-6.2/sources/gst-plugins/gst-nvinfer
$sudo make clean install CUDA_VER=11.8 ENABLE_WSL2=1

compile/link gst-nvdspreprocess plugin

$cd /opt/nvidia/deepstream/deepstream-6.2/sources/gst-plugins/gst-nvdspreprocess
$sudo make clean install CUDA_VER=11.8 ENABLE_WSL2=1

compile/link deepstream-test1 application

cd /opt/nvidia/deepstream/deepstream-6.2/sources/apps/sample_apps/deepstream-test1
$sudo make CUDA_VER=11.8 ENABLE_WSL2=1

start deepstream-test1 application

cd /opt/nvidia/deepstream/deepstream-6.2/sources/apps/sample_apps/deepstream-test1
$sudo ./deepstream-test1-app /opt/nvidia/deepstream/deepstream-6.2/samples/streams/sample_720p.h264

Let me know if it helps

Hi @sylvain-prevost,

I don't know exactly what I did wrong, but I have done it all over again and followed these last steps as you told me and it works! Thank you very much!
