Build OpenCV 3.4 with CUDA on NVIDIA Jetson TX2

Hello everyone!

I’m installing OpenCV 3.4 with CUDA on my TX2.
I’m facing problems.
first of all my Jetson configurations:
JETPACK 4.2
Ubuntu 18.04

During the installation process, I get this error:

I’ve made this change in ‘/usr/local/cuda-10.0/include/cuda_gl_interop.h’
but still the same error

I’m following Jetsonhacks to install opencv 3.4 with cuda
Jetson configurations:
JETPACK 4.2
Ubuntu 18.04

Just a comment: Do you really need to install OpenCV 3.4? By upgrading/installing newer OpenCV I’ve destroyed my OpenCV installation many times and i’ve had to re-flash my hardware several times. If you can live with OpenCV3.3 i would recommend you just flash using the new Jetpack 4.2 it will include Cuda 10 and OpenCV 3.3.0 for you.

Thanks for your reply.
I know that jetpack 4.2 include opencv3.3
But I want to use OpenCV with Cuda and JetsonHacks has a tutorial to install OpenCV 3.4 with CUDA.

This looks weird to me. Check everything is ok with:

sha1sum -c /etc/nv_tegra_release

If all ok, you may find the lib in /usr/lib/aarch64-linux-gnu/tegra, so you may try to make a symlink such as (no Nano for checking, I’m on a TX2 running R28.2.0):

sudo su
cd /usr/lib/aarch64-linux-gnu
ln -s tegra/libGL.so.1 libGL.so
exit

For building opencv-3.4, you may have a look to this script installing opencv-3.4.0 on TX2. For nano you would change CUDA_ARCH_BIN=“6.2” to CUDA_ARCH_BIN=“5.3”. You may also change for 3.4.1 version.
But you may also use this script for installing opencv4 for Nano.

Hello!!
Thank so for your help. I’ve installed OpenCV 3.4 with CUDA on my jetson TX2.
Thanks for sharing the script: https://github.com/AastaNV/JEP/blob/master/script/install_opencv4.0.0_Nano.sh

Now I have other problems… I don’t know why…
Onboard camera not open.
I run my python script:

import numpy as np
import cv2

cap = cv2.VideoCapture("nvcamerasrc ! video/x-raw(memory:NVMM), width=(int)1280, height=(int)720, format=(string)I420, framerate=(fraction)30/1 ! nvvidconv flip-method=4 ! video/x-raw, format=(string)BGRx ! videoconvert ! video/x-raw, format=(string)BGR ! appsink")

while(True):
    #Captura frame por frame
    ret, img = cap.read()
    gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
    cv2.imshow('Video Output', img)
    k = cv2.waitKey(10) & 0xFF
    if k==27:
        break



#cuando todas las cosas esten hechas, dejar la captura
cap.release()
cv2.destroyAllWindows()

I don’t get errors but the camera not open, just waiting:

diego@diego-desktop:~/Documents/OpenCV_examples$ python cannyDetection.py
Called with args:
Namespace(video_device=0)

I waited 20 minutes and nothing happened.

You may add this line for checking your opencv lib from python:

print(cv2.getBuildInformation())

and check if it has gstreamer support. If not the expected opencv version, you may read this.

I get this:

apparently GStreamer is enabled

I’m having a similar issue and ‘sha1sum -c /etc/nv_tegra_release’ says libv4lconvert.so doesn’t pass the check. How to deal with this? I tried to compile without solving this problem, and the complied opencv does not have libv4l features.

Any idea what may have caused this problem and how to solve it? (Can it be version problem? But I cannot find another version of libv4l-dev through apt-get)

Many thanks!

HI buddy! Honey_patouceul

I’m still facing issues with OpenCV. I can’t open the onboard camera.

GStreamer is enabled…
All started when I upgraded the Jetpack to 4.2
after that Caffe was not working, I figured out and then OpenCV 3.3 was not working, after that, I’ve installed OpenCV 3.4 and is not working…
When I tried to go back to jetpack 3.3 there were errors during installation like “Cuda was not installed please do it manually”
I don’t know…

diego@diego-desktop:~/Documents/OpenCV_examples$ sudo python Captura_video.py
VIDEOIO ERROR: V4L: device nvcamerasrc ! video/x-raw(memory:NVMM), width=(int)1920, height=(int)1080, format=(string)I420, framerate=(fraction)30/1 ! nvtee ! nvvidconv flip-method=2 ! video/x-raw(memory:NVMM), format=(string)I420 ! nvoverlaysink -e ! appsink: Unable to query number of channels

You should first check that basic L4T binaries are OK with:

sha1sum -c /etc/nv_tegra_release

If something is not ok you would have to fix it. May be reflash.

Then you would have to be sure CUDA is installed. When installed, you would have it installed into /usr/local/cuda (which is a symlink to /usr/local/cuda-X.Y depending on version). If this is not your case, you would have first to fix that. With JetPack you can run post-install only, it wouldn’t need to flash, everything would be installed through ethernet.

It seems for now that on your TX2 python uses the cv2.so from JetPack, as shown version is 3.3.1. This version has gstreamer support, but no CUDA support. I can’t tell a clean way for fixing this, but for a nasty fix you may check this and adapt for your case.

Another thing is that nvcamerasrc is deprecated in new releases, so you would use nvarguscamerasrc instead, with NV12 format instead of I420. Not sure if you need nvtee in your pipeline.

Last, and maybe most important, you would remove nvoverlaysink from the pipeline (and ‘-e’, which is only for gst-launch). Being a pure sink, it doesn’t output to appsink, so your opencv app won’t receive frames. This may be the other main point.

is there a workaround if:

sha1sum -c /etc/nv_tegra_release

fails at this?

I think that is the root of my problem. I’m trying to compile opencv 3.4.6 with contrib files:

During a flash the base sample rootfs is overlaid with some boot files, plus the NVIDIA-specific files. This is one of the NVIDIA-specific files:

/usr/lib/aarch64-linux-gnu/libv4lconvert.so: FAILED

If you still have your “Linux_for_Tegra/” subdirectory from the flash, then you have the driver package (driver package is the real flash software, the GUI is just a front end). Running the command “sudo ./apply_binaries.sh” is what overlays those files over the sample rootfs.

When apply_binaries.sh runs it basically just uses sudo to unpack some of the “Linux_for_Tegra/nv_tegra/” archives. In your case you’ll see what you want by listing this from the “Linux_for_Tegra/nv_tegra/” directory:

bunzip2 < nvidia_drivers.tbz2 | tar --list | grep libv4lconvert.so

Any method which unpacks this and puts it on the TX2 works if sudo is used. It is harmless to reinstall all of those files (the ones which are correct would be replaced with themselves).

  • You can copy it from the "Linux_for_Tegra/rootfs/usr/lib/aarch64-linux-gnu/liv4lconvert.so" location if you have that directory...flash would have used "apply_binaries.sh" to place this here. The last example is just a variation on this.
  • You can copy "nvidia_drivers.tbz2" to the TX2 in "/", and then:
    cd /
    sudo tar xvfj nvidia_drivers.tbz2
    # Optional:
    sudo rm nvidia_drivers.tbz2
    
  • You could run apply_binaries.sh from your host with an option to place content in a blank directory and just scp the file from there. Example (assumes you have account "ubuntu" on the TX2):
    cd /where/ever/it/is/Linux_for_Tegra/
    mkdir ~/deleteme
    sudo ./apply_binaries.sh --root ~/deleteme
    cd ~/deleteme/usr/lib/aarch64-linux-gnu
    scp libv4lconvert.so ubuntu@ip_address_of_tx2/~/Downloads
    ssh ubuntu@ip_address_of_tx2
    cd Downloads
    sudo cp libv4lconvert.so /usr/lib/aarch64-linux-gnu
    sudo chown root.root /usr/lib/aarch64-linux-gnu/libv4lconvert.so
    

After this the sha1sum should be valid.

worked perfectly thanks
