Can you double check your environment? The CUDA version should be 11.7 for DeepStream 6.1.1, please refer to the compatibility matrix: Quickstart Guide — DeepStream 6.1.1 Release documentation

anusha.manila · November 17, 2022, 6:19pm

I have installed CUDA Version 11.7 with update 1 as mentioned in the document
“Install CUDA Toolkit 11.7.1 (CUDA 11.7 Update 1) and NVIDIA driver 515.65.01”

yingliu · November 18, 2022, 1:53am

I misunderstood it when saw tensorRT version as “8.4.1.1+cuda11.6”, sorry for it. Please help provide the output of nvidia-smi on your host.
Your card is Tesla series, please be noted that it’s compute card, not for display, you need use sink (for example Fakesink) or files or RTSP stream other than EGL sink. You can refer below example which uses fakesink sink:

deepstream-app -c /opt/nvidia/deepstream/deepstream-6.1/samples/configs/deepstream-app/source2_1080p_dec_infer-resnet_demux_int8.txt

anusha.manila · November 18, 2022, 3:53am

Thank you Yingliu for the response.
Probably, the display driver for Xorg is installed on Tesla T4 as you mentioned.

I’ll check it out Monday and get back to you.

anusha.manila · November 21, 2022, 11:11pm

I’ve removed the xorg display on Tesla T4 and it is used for compute only now.

Without root, deepstream-app fails to start and with root Tensorrt doesn’t work.

The Python bindings of test1 gives me black screen output when I run “python3 deepstream-test1.py …/…/…/…/samples/streams/sample_720p.h264”

Any idea what’s wrong?

fanzh · November 22, 2022, 6:04am

from the logs, it can’t find “libnvinfer.so”, can you find it in /usr/lib/x86_64-linux-gnu/libnvinfer.so?
please install dependency libs according to Quickstart Guide — DeepStream 6.1.1 Release documentation

anusha.manila · November 22, 2022, 4:34pm

I see the following when I try to install the TensorRT dependencies.
It upgrades to Cuda 11.8, which we don’t want.
Cleaning the apt cache didn’t help. How to avoid the Cuda 11.8 upgrade?

Note:
Because of the above issue, I’ve installed TensorRT 8.4.1.5 from the tar file and added the path of libnvinfer.so files to bashrc
So I am able to import tensorrt from python scripts only.

fanzh · November 23, 2022, 3:22am

GStreamer 1.16.2
NVIDIA driver 515.65.01
CUDA 11.7 Update 1
TensorRT 8.4.1.5
please uninstall all the above dependency libs, and install them step by step according to Quickstart Guide — DeepStream 6.1.1 Release documentation
you can use these command to check the version:
CUDA version nvcc -V
dpkg -l |grep TensorRT
dpkg -l | grep gstreamer
dpkg -l|grep cudnn

anusha.manila · November 23, 2022, 6:07pm

The above issue is seen after I’ve reinstalled Ubuntu 20.04 and tried again by following the steps in the documentation
I need to know how to install TensorRT libraries without upgrading cuda from 11.7.1 to 11.8. Please let me know if you have any suggestions.

fanzh · November 24, 2022, 6:16am

that cuda-ccl-11-8 is TensorRT 's dependency lib, not mean cuda will be upgraded to 11.8, you can use “nvcc -V” to get current cuda vesion.
or you try to install TensorRT first, then install cuda11.7？
or we suggest to use deepstream docker, which has installed all dependency libs, here is the link: DeepStream | NVIDIA NGC

anusha.manila · December 5, 2022, 11:18pm

Created the container from below command:

docker run -itd --net=host --runtime nvidia -e DISPLAY=$DISPLAY -w /opt/nvidia/deepstream/deepstream-6.1 -v /tmp/.X11-unix/:/tmp/.X11-unix nvcr.io/nvidia/deepstream:6.1.1-samples

Using the docker container, I’m facing the below issues:

deepstream-app -c /opt/nvidia/deepstream/deepstream-6.1/samples/configs/deepstream-app/source2_1080p_dec_infer-resnet_demux_int8.txt

The above command gives the below output

However, if other config files are used, they show blank window for a second and then end up with a segmentation fault

deepstream-app -c /opt/nvidia/deepstream/deepstream-6.1/samples/configs/deepstream-app/source30_1080p_dec_infer-resnet_tiled_display_int8.txt

from your screenshot, that sample run successfully, 30 represents fps.
about the second case, you can set sink display type to fakesink, it will not display video, the setting looks like:
[sink0]
enable=1
#Type - 1=FakeSink 2=EglSink/nv3dsink (Jetson only) 3=File
type=1

Thanks Fanzh, deepstream-app runs fine but deepstream-test1-app doesn’t.
Could you tell me what could have caused Segmentation fault?

Similarly, When I try to run Object Detector Yolo, the engine created successfully but no output is seen. The Pipeline seems to run but ends with segmentation fault.

please try to replace nveglglessink with fakesink in deepstream_test1_app.c, then rebuild and run.
if still crash, please do “export GST_DEBUG=6”, then run again, send us the terminal logs.
can you debug it? for example:
$: gdb ./deepstream-test1-app
$ set args ./deepstream-test1-app /opt/nvidia/deepstream/deepstream/samples/streams/sample_720p.h264
$ bt
then send us the stack information.

I’ve replaced with fakesink and attached the log here
log.txt (5.5 MB)

App is running inside the docker container and I saved the log in a text file.
Let me know if there is a better way to share the log.

fanzh · December 8, 2022, 3:32am

did you try this? need to check if it is related to nveglglessink sink.

anusha.manila · December 8, 2022, 4:15am

Yes I have now enabled the fakesink and the previous log was without fakesink.
Please find the new log attached.

gst_element_factory_create:e[00m creating element “nveglglessink” named “nvvideo-renderer”
from the logs, it still uses nveglglessink, did you rebuild the code after modifying to fakesink? and the command is: ./deepstream-test1-app /opt/nvidia/deepstream/deepstream/samples/streams/sample_720p.h264

anusha.manila · December 8, 2022, 6:38am

Perhaps, I missed to re run the make command inside the docker container. Sorry about that.
The new log for sample_720.h264 is attached here. Now I don’t see the nveglglessink in the log.
