I think it's up to your VNC environment whether OpenGLES commands are correctly transferred to another PC or not, Isn't it ?

no i mean i want to run it via SSH, no VNC environment, just plain old SSH into the machine and want to run it.
will unset DISPLAY help ? or maybe export DISPLAY:=1 or something ?
how about
export DISPLAY=:0
nope, doesn't really work on the nano
i've tried:
if [ -z "$DISPLAY" ]
then
startx > /dev/null 2>&1 &
export DISPLAY=:1.0
fi
for the above: the tflite models are loaded, but inferencing doesnt work, no output, and sometimes there's error as https://github.com/terryky/tflite_gles_app/issues/11
if [ -z "$DISPLAY" ]
then
DISPLAY=:0.0 glxinfo > /dev/null 2>&1
if [ $? -ne 0 ]
then
echo "starting new x server at :0.0"
startx > /dev/null 2>&1 &
else
echo "connecting to existing x server at :0.0"
fi
export DISPLAY=:0.0
else
echo "already configured for x server at $DISPLAY"
fi
i've tried this as well: which works on ssh, but needs a display connected with the nano, in that case i am getting the outputs on my ssh terminal, and the window is created on the display connected to nano, that is not really what i want.
could it be possible to run the examples without any display connected to the nano ? like just ssh into nano and run the gles app

I've added a new config named "headless". Could you try below ?
(ssh to jetson with X forwarding)
$ ssh -X jetson@192.168.1.1
(On jetson)
$ export DISPLAY=:10.0
$ cd ~/work/tflite_gles_app/gl2blazeface
$ make clean
$ make TARGET_ENV=headless
$ ./gl2blazeface

thanks i will give it a try !
Hi, an update on this,
i tried out the below stuff
(ssh to jetson with X forwarding) $ ssh -X jetson@192.168.1.1 (On jetson) $ export DISPLAY=:10.0 $ cd ~/work/tflite_gles_app/gl2blazeface $ make clean $ make TARGET_ENV=headless $ ./gl2blazeface
and i added printf("%d\n", detection->num)
and ran ./gl2blazeface -x
to run the example image, the model is loaded, and its running, but i the number of detected faces as 0, something to note: i dont have the X forwared session rendered at my end (this might be an issue at my end)
is the gl window rendering required ? either directly on the nano, or as an X forwarded session ? i am preferring to not use X session forwarded in SSH, since the connection is slow.
I did printf
for all the debug strings, so the tflite inference time is printed fine, but some issues, below :
-x
and all the images in assets
folder, here i am getting score as 0.0
0
render_detect_region
i put a printf
for buf
, but no output, so detection->num
is again 0hmmmm. I don't understand why gl2blazeface doesn't work although gl2classification work well. They are almost same implementation. Don't you have any OpenGL error logs ?

Yep, I agree that. However, do you mean you don't want to see any OpenGL window ? (you want to get inference result by just a console text instead of OpenGL visualization ?)
Yess i only want the inference results on the console, not on window !, i'll modify the examples so as the debug string and other info are pushed to the console
No i dont have any opengl error logs, just that the number of faces detected is always 0
i think since the window is not showing up, maybe just a black screen is sent to the model ? i am just guessing.
On current implementation, OpenGL is required in order to preprocess input images. (resize, crop, affine transform, color conversion (YUYA->RGB)). and unfortunately, current implementation requires showing window in order to use OpenGL.
FYI.
This is a screen capture of gl2blazeface forwarded to WindowsPC from Jetson nano. It works well.
I used VcXsrv
as a X Server.
hmm okay, thanks a lot !
hey @satyajitghana, @terryky I am also trying to run the trt_posnet in headless mode, is it possible to do that,?
Hey Terry, Thanks for this awesome work !
One query, how do I run these examples headless ? without any display attached to the nano ?
