Error while building deepstream_tlt_apps

Hardware Platform: GPU (Tesla T4)
DeepStream Version: 5.0
TensorRT Version: 7.0.0.11
NVIDIA GPU Driver Version: 440.33.01
Cuda Version: 10.2
Cudnn Version: 7.6.5
Ubuntu Version: 18.04

I installed deepstream and TensorRt and I’m trying to run some examples but I have a problem while trying to build the deepstream_tlt_apps:

Can you paste your full command when you build the deepstream_tlt_apps?
BTW, which readme did you follow?

So I followed the instructions from here: https://github.com/NVIDIA-AI-IOT/deepstream_tlt_apps
I executed the download part and the build just the second set of instructions, from export DS_SRC_PATH=…

And the command I used for building is just make and then I got that error.

1)Could you try to search NvCaffeParser.h in your device?
2)Refer to Error while running SSD provided in Deepstream

  1. Yes, I can find the NvCaffeParser.h in TensorRT/include.
  2. I followed the instructions from 2) and added the correct path in the Makefile but I still got the same error.
    Here’s my Makefile, maybe I missed something.

CFLAGS+= -I$(DS_SRC_PATH)/sources/includes -I/home/rockefella09/TensorRT-7.0.0.11/include

SRCS:= $(wildcard *.c)

INCS:= $(wildcard *.h)

PKGS:= gstreamer-1.0

OBJS:= $(SRCS:.c=.o)

CFLAGS+= pkg-config --cflags $(PKGS)

LIBS:= pkg-config --libs $(PKGS) -L/home/rockefella09/TensorRT-7.0.0.11/lib

LIBS+= -L$(LIB_INSTALL_DIR) -lnvdsgst_meta -lnvds_meta
-Wl,-rpath,$(LIB_INSTALL_DIR)

  1. That’s your head file under your TRT OSS folder only. Not sure when you were missing the head file. It should be available, normally at /usr/include/x86_64-linux-gnu/. How did you install TensorRT7? Can you share your step?
  2. Please modify the Makefile in each child folder too. That will solve your issue.
  1. I followed this: https://docs.nvidia.com/deeplearning/tensorrt/install-guide/index.html#installing-tar and my TensorRT file is in /home/TensorRT-7.0.0.11. Also I do not have any files related to TensorRT in /usr/include/x86_64-linux-gnu/

  2. Yes that solved the problem, but it seams that my TensorRT installation is still broken because when I try to run demo:

    ./deepstream-custom -c pgie_frcnn_tlt_config.txt -i $DS_SRC_PATH/samples/streams/sample_720p.h264 -d

I get some errors which seems to be caused by TensorRT installation:

From your latest log, faster_rcnn_resnet10.etlt_b1_gpu0_fp16.engine is generated successfully.
Just meet the error " Internal data stream error".

Please set below and run again.
$ export DISPLAY=:0

Now it works (I have no error anymore and it seams like it’s running). I used the “-d” because I wanted to display the results, but without success (it hangs in Running…). I am using a cloud compute engine from GCP and I am connected to the display via remotedesktop hoping that I can see the predictions on the video but as I mentions it hangs.

If I remove the “-d” flag, it seems like it’s working till the end but I can’t figure where I can find the resulted video.

There is an output file: out.h264

I was blind, sorry.

Thank you for your help and patience.
