DeepStream SDK does not work

Accelerated Computing Intelligent Video Analytics DeepStream SDK

After Installing DeepStream SDK on Jetson,I use the command line “$ nvgstiva-app -c ${HOME}/configs/PGIE-FP16-CarType-CarMake-CarColor.txt” to confirm that the DeepStream installation is successful,but fail:

$ nvgstiva-app -c ${HOME}/configs/PGIE-FP16-CarType-CarMake-CarColor.txt

Hi Neon, try

sudo rm -rf ${HOME}/.cache/* and then re run

nvgstiva-app -c ${HOME}/configs/PGIE-FP16-CarType-CarMake-CarColor.txt

Cheers

Hi,

Strange that it is failing on your side, it was pretty easy to make it run, this is my scenario at a Jetson Tx1 with JetPack 3.2:

nvidia@tegra-ubuntu:~$ uname -a
Linux tegra-ubuntu 4.4.38-tegra #1 SMP PREEMPT Thu Mar 1 20:44:58 PST 2018 aarch64 aarch64 aarch64 GNU/Linux
nvidia@tegra-ubuntu:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 16.04 LTS
Release: 16.04
Codename: xenial
nvidia@tegra-ubuntu:~$ nvgstiva-app -c ${HOME}/configs/PGIE-FP16-CarType-CarMake-CarColor.txt

Installed with instructions from deepstream_sdk_on_getson_README.txt at section “Installing DeepStream SDK on Jetson”

nvgstiva-app is basically a Gstreamer application, you may get more debug information if using GST_DEBUG variables, for example:

GST_DEBUG=3 nvgstiva-app -c ${HOME}/configs/PGIE-FP16-CarType-CarMake-CarColor.txt

More than three is just too much logging being printed, like:
GST_DEBUG=4 nvgstiva-app -c ${HOME}/configs/PGIE-FP16-CarType-CarMake-CarColor.txt

rror while initialize EGL display connection
nvbuf_utils: Invalid width=0 height=0 layout=0
NvBufferCreateEx with memtag 0 failed
nvcaffegie: NvBufferCreateEx failed
What is the problem?anyone met and how to solve? Thanks.

NvMap failed to allocate memory due to some parameters error.
I will try to reproduce on my side.

Thanks

can you specify the detailes of the setup? i see you use 4 sinks, you connect 4 devices with 4 monitors through
HDMI cable or something else?

Hi neon-1004,

Is this still an issue on your side? Any result can be shared?

Thanks
