implementing the code on aarch64 nvidia jetson [linux] #655

AndreV84 · 2020-04-26T07:24:52Z

Hi Guys,
You mentioned Android & IoS devices;
I am just wondering if the code will run on arm 64 nvidia jetson [ tegra linux];

You need to modify the code a little bit to make MediaPipe on jetso. For glog: #304. For GPU support: #305

AndreV84 · 2020-04-29T15:11:47Z

glog and gpu helloworld I can bypass and run;
However, I can not find a clue how to build and run hand-tracking example;

jiuqiant · 2020-04-29T18:32:14Z

Can you build it by running the following command?

bazel build -c opt --copt -DMESA_EGL_NO_X11_HEADERS --copt -DEGL_NO_X11 \
    mediapipe/examples/desktop/hand_tracking:hand_tracking_gpu

To have a video-in-video-out demo, you can do

GLOG_logtostderr=1 bazel-bin/mediapipe/examples/desktop/hand_tracking/hand_tracking_gpu \
    --calculator_graph_config_file=mediapipe/graphs/hand_tracking/hand_tracking_mobile.pbtxt \

    --output_video_path=/path/to/output

@jiuqiant Thank you for your response!
` bazel build -c opt --copt -DMESA_EGL_NO_X11_HEADERS --copt -DEGL_NO_X11 \

it provides output;
however also it would be reat to know how to get numeric coordinates of lines and dots/joints? not a graphical representation, but coordinates? is it possible?
Also how to get input from webcamera and direct it to file? to display? to text coordinates?
Thanks

It's possible to get the coordinates/landmarks out of the graph. The solution is to observe the "hand_landmarks" stream in the main function by using an output stream poller. Here is a similar issue for your reference: #200. If you are looking for some example code, please take a look at #200 (comment).

Looks great! Just want to double check that it's running on Nvidia Jetson, right?

Looks nice!
Just FYI, there is a multi-hand tracking demo already available in mediapipe that would better suit that test video:
https://mediapipe.readthedocs.io/en/latest/multi_hand_tracking_desktop.html?highlight=multi#tensorflow-lite-multi-hand-tracking-demo-with-webcam-gpu

It would also be great if you could document concisely what all you had to do for getting things running on Nvidia Jetson. We are interested in officially supporting that platform, and others could benefit from your experience. .

AndreV84 · 2020-05-01T10:41:31Z

exactly! it was executed on nvidia jetson.
In the future, I will try running it on various jetson models.
They typically have CSI Bayers camera which is not accessible through v4l2l, unless via v4l2loopback where they can be converted to I420/RGB, whatever

AndreV84 · 2020-05-01T15:00:56Z

here are the steps
https://github.com/AndreV84/Jetson/blob/master/madiapipe.sh
then I install opencv 4.3
https://github.com/AndreV84/Jetson/blob/master/opencv43
then edit file WORKSPACES
`new_local_repository(
name = "linux_opencv",
build_file = "@//third_party:opencv_linux.BUILD",
path = "/usr/local/opencv-4.3.0-dev/",

then edit the file third-party/
cc_library(
name = "opencv",
srcs = glob(
[
"lib/libopencv_core.so",
"lib/libopencv_calib3d.so",
"lib/libopencv_features2d.so",

"lib/libopencv_video.so",
"lib/libopencv_videoio.so",
],
),
hdrs = glob(["include/opencv4/**/.h"]),
includes = ["include/opencv4"],
linkstatic = 1,
visibility = ["//visibility:public"],
)

AndreV84 · 2020-05-01T15:54:56Z

then I can execute
bazel build -c opt --copt -DMESA_EGL_NO_X11_HEADERS --copt -DEGL_NO_X11 mediapipe/examples/desktop/hand_tracking:hand_tracking_gpu

GLOG_logtostderr=1 bazel-bin/mediapipe/examples/desktop/hand_tracking/hand_tracking_gpu --calculator_graph_config_file=mediapipe/graphs/hand_tracking/hand_tracking_mobile.pbtxt --input_video_path=/home/nvidia/Downloads/Big_Buck_Bunny_1080_10s_30MB.mp4 --output_video_path=/home/nvidia/Downloads/output.mp4

the latter will throw an error though as video0 is csi Bayers sensor;
How do I say to it to read from /dev/video2 instead?
In order to get CSI Bayers into loopback I am doing the following:
`cd /usr/src/linux-headers-4.9.140-tegra-ubuntu18.04_aarch64/kernel-4.9

dropped in latter release##make modules_prepare

mkdir v4l2loopback
git clone https://github.com/umlaeute/v4l2loopback.git v4l2loopback
cd v4l2loopback && git checkout -b v0.10.0
make
make install
apt-get install -y v4l2loopback-dkms v4l2loopback-utils
modprobe v4l2loopback devices=1 video_nr=2 exclusive_caps=1
echo options v4l2loopback devices=1 video_nr=2 exclusive_caps=1 > /etc/modprobe.d/v4l2loopback.conf
echo v4l2loopback > /etc/modules
update-initramfs -uu may find the method posted here https://www.viziochron.com/xavier#h.p__yIE9-ovqscA then I start the loopback to map the CSI device to /dev/video2gst-launch-1.0 -v nvarguscamerasrc ! 'video/x-raw(memory:NVMM), format=NV12, width=1920, height=1080, framerate=30/1' ! nvvidconv ! 'video/x-raw, width=640, height=480, format=I420, framerate=30/1' ! videoconvert ! identity drop-allocation=1 ! 'video/x-raw, width=640, height=480, format=RGB, framerate=30/1' ! v4l2sink device=/dev/video2`

The outputs are as follows; though I do not see any output, but text

will --input_video_path=/dev/video2 be a correct link to webcam?

jiuqiant · 2020-05-01T17:50:06Z

will --input_video_path=/dev/video2 be a correct link to webcam?

If you don't specify input_video_path, it will ask opencv video capture to get frames from the webcam directly. See this logic at https://gist.github.com/eknight7/d4a57504c8f866fc80c0eb2c61ff6b4f#file-multi_hand_tracking_run_graph_cpu_main-cc-L52.

AndreV84 · 2020-05-01T19:53:44Z

@jiuqiant by default opencv reads from /dev/video0 - it doesn't work for webcam mode as it is CSI Bayer's sensor device. webcam on jetsons would be on /dev/video1[2] etc
from the CSI sensor I can read with opencv e.g. with the code below

`#include <unistd.h>
#include <iostream>
#include <signal.h>

#include <opencv2/opencv.hpp>
#include <opencv2/videoio.hpp>
#include <opencv2/highgui.hpp>


static cv::VideoCapture *capPtr=NULL;
void my_handler(int s){
           printf("Caught signal %d\n",s);
       if(capPtr)
        capPtr->release();
           exit(1); 
}

int main()
{
    /* Install handler for catching Ctrl-C and close camera so that Argus keeps ok */
    struct sigaction sigIntHandler;
    sigIntHandler.sa_handler = my_handler;
    sigemptyset(&sigIntHandler.sa_mask);
    sigIntHandler.sa_flags = 0;
    sigaction(SIGINT, &sigIntHandler, NULL);


    const char* gst =  "nvarguscamerasrc ! video/x-raw(memory:NVMM), width=640, height=480 !  nvvidconv ! video/x-raw,format=I420 ! appsink";
    capPtr = new cv::VideoCapture(gst, cv::CAP_GSTREAMER);
    if(!capPtr->isOpened()) {
    std::cout<<"Failed to open camera."<<std::endl;
    return (-1);
    }

    cv::namedWindow("MyCameraPreview", cv::WINDOW_AUTOSIZE);
    cv::Mat frame_in;
    while(1)
    {
        if (!capPtr->read(frame_in)) {
        std::cout<<"Capture read error"<<std::endl;
        break;
    }
    else  {
        cv::cvtColor(frame_in, frame_in, cv::COLOR_YUV2BGR_I420);
        cv::imshow("MyCameraPreview",frame_in);
        if((char)cv::waitKey(1) == (char)27)
            break;
    }    
    }

    capPtr->release();
    delete capPtr;
    return 0;
}`

otherwise /dev/vide0 will be unreadable, and only /dev/video2 will work as webcam

from -capture.open(0);

but which file do I edit in the mediapipe folder? is there any way to read from csi bayers sensor directly? e.g. via incorporating the gst nvargussrc from the excerpt above?

AndreV84 · 2020-05-01T21:17:21Z

could you also advise regarding if it is possible to use mediapipe to localize gaze position x, y from image? can you get through the implementation of it with jetson?

AndreV84 · 2020-05-01T22:36:59Z

I can get 1 hand with v4l2loopback from sensor 0 - > 2
Somehow the loop may be omitted to read from 0 directly;
It will speed up dramatically the process;

AndreV84 · 2020-05-01T22:38:51Z

what are the options to 'sink'/write the output stream to a file? or to forward it further to a virtual device? what can be done with arguments? passed through the command line? for the output stream?

I mentioned an approach to get landmarks data in #655 (comment). Are you able to do this in the main function already? If yes, it's pretty easy to sink this to a file by using std::ofstream.

AndreV84 · 2020-05-01T22:52:54Z

I missed it; was focusing on redirection of the video stream;
I shall try following your direction again
thank you for pointing out.

Do I have to build the code from https://github.com/mgyong/mediapipe-issue200 ?
for object detection example? in order to be able to read the landmark coordinates from outpput stream?
I am trying to get the code to read from nvargus directly without v4l2loopback:

AndreV84 · 2020-05-06T18:41:13Z

@mgyong Thank you for your message. I will try to get the existing draft more clear. There is still much of variability which might be messed by single Readme.md file; For example as of Opencv 4.3 installation which is a separate story as it will be up to individual which components to include in opencv installation. Also the issue of direct read from nvargus will still need to be investigated to avoid CPU expensive v4loopback iteration which is not really necessary.

AndreV84 · 2020-05-06T19:21:37Z

@mgyong you may find the steps at https://github.com/AndreV84/mediapipe/blob/master/README.md

AndreV84 · 2020-05-07T11:56:27Z

I can probably pack it into a Docker file; for Jetson l4t

mgyong · 2020-05-07T19:25:08Z

@AndreV84 Thanks. This is great. We will look into incorporating a link to this in our documentation.

We now have a community driven repo awesome MediaPipe mediapipe.orgI where we link related repos. I have invited you to make change to include your repo doc into the awesosme MediaPipe repo

If you have time, it would be great to include a cross compilation section (where folks can use a Docker file to build the MediaPipe example into a binary in container on desktop and deploy binary to the Nvidia device)

I am trying to revise and rebuild the mediapipe on newer Jetson OS release with newer opencv version; Once implemented I will update the guide. If there will be issues I will askk for help. Thanks

we were able to get progress with it;
will try to do dockerized deployment at some point in the future with it

@jiuqiant by default opencv reads from /dev/video0 - it doesn't work for webcam mode as it is CSI Bayer's sensor device. webcam on jetsons would be on /dev/video1[2] etc
from the CSI sensor I can read with opencv e.g. with the code below

`#include <unistd.h>
#include <iostream>
#include <signal.h>

#include <opencv2/opencv.hpp>
#include <opencv2/videoio.hpp>
#include <opencv2/highgui.hpp>


static cv::VideoCapture *capPtr=NULL;
void my_handler(int s){
           printf("Caught signal %d\n",s);
       if(capPtr)
        capPtr->release();
           exit(1); 
}

int main()
{
    /* Install handler for catching Ctrl-C and close camera so that Argus keeps ok */
    struct sigaction sigIntHandler;
    sigIntHandler.sa_handler = my_handler;
    sigemptyset(&sigIntHandler.sa_mask);
    sigIntHandler.sa_flags = 0;
    sigaction(SIGINT, &sigIntHandler, NULL);


    const char* gst =  "nvarguscamerasrc ! video/x-raw(memory:NVMM), width=640, height=480 !  nvvidconv ! video/x-raw,format=I420 ! appsink";
    capPtr = new cv::VideoCapture(gst, cv::CAP_GSTREAMER);
    if(!capPtr->isOpened()) {
    std::cout<<"Failed to open camera."<<std::endl;
    return (-1);
    }

    cv::namedWindow("MyCameraPreview", cv::WINDOW_AUTOSIZE);
    cv::Mat frame_in;
    while(1)
    {
        if (!capPtr->read(frame_in)) {
        std::cout<<"Capture read error"<<std::endl;
        break;
    }
    else  {
        cv::cvtColor(frame_in, frame_in, cv::COLOR_YUV2BGR_I420);
        cv::imshow("MyCameraPreview",frame_in);
        if((char)cv::waitKey(1) == (char)27)
            break;
    }    
    }

    capPtr->release();
    delete capPtr;
    return 0;
}`

otherwise /dev/vide0 will be unreadable, and only /dev/video2 will work as webcam

I tryied to implement the above code, up until the color conversion cv::cvtColor(frame_in, frame_in, cv::COLOR_YUV2BGR_I420); but then when i fed "frame_in" into mediapipe i just get an empty image
The olny difference is that mediapipe graph wnats a SRGBA image instead of RGB so i used the cv::COLOR_YUV2RGBA_I420 code
i also send a similar issue to nvidia.developer forum

@radisc
you may refer to the solution listed there : https://github.com/AndreV84/mediapipe
in particular the patched for CSI file is https://github.com/AndreV84/mediapipe/blob/master/demo_run_graph_main_gpu_mod.cc

Yes, thank you, i already saw that implementation, but i was trying to do something similar without using videoconvert, because as far as i know it is pretty CPU intensive and maybe use instead the nvvideoconvert plugin from the deepstream package

AndreV84 · 2021-01-18T18:23:45Z

@radisc is your system - Jetson?
the patched file uses

   const char* gst =  "nvarguscamerasrc ! video/x-raw(memory:NVMM), width=640, height=480 !  nvvidconv ! video/x-raw,format=I420 ! appsink";

there is no videoconvert

Yes, jetson NX

Oh, sorry i missed the patch, however i tried this also, and i manage to convert it and visualize it before feeding it to mediapipe.

Instead of cv::cvtColor(camera_frame_raw, camera_frame, cv::COLOR_BGR2RGB); i do cv::cvtColor(camera_frame_raw, camera_frame, cv:: cv::COLOR_YUV2RGBA_I420);

But mediapipe doens't seem to like it

AndreV84 · 2021-01-18T18:34:49Z

the patched file uses

        cv::cvtColor(frame_in, frame_in, cv::COLOR_YUV2BGR_I420);

as long as you execute the patched file on jetson with CSI camera it shoudl work as is

radisc · 2021-01-18T18:43:41Z

Ok, i followed the link you provided https://github.com/AndreV84/mediapipe/blob/1aa89d348a91dad0d63e0b34b7ec50f668b4d232/demo_run_graph_main_gpu_mod.cc#L70
i can't see the patched code, however i will try later using RGB instead of RGBA and changing also SRGBA to SRGB

AndreV84 · 2021-01-18T18:52:13Z

the file has

    cv::cvtColor(camera_frame_raw, camera_frame, cv::COLOR_BGR2RGB);

AndreV84 · 2021-01-18T18:54:11Z

actually the file has the vcideoconvert that wasn't presented in the variant of the code quoted by you previously in earlier post that havent had the videoconvert

 const char* gst =  "nvarguscamerasrc ! video/x-raw(memory:NVMM), width=1280, height=720, framerate=30/1 !  nvvidconv ! video/x-raw,format=BGRx ! videoconvert ! video/x-raw, format=BGR ! appsink";

once you got the default scenario to work you could try adjusting certain parameters then rebuilding

AndreV84 · 2021-01-18T18:55:17Z

what is your hardware? jetson? which model? not jetson? arm? x86?

radisc · 2021-01-18T18:59:20Z

what is your hardware? jetson? which model? not jetson? arm? x86?

I'm using a Jetson Xavier NX, the link you provided has videoconvert in it, is there another file that i'm missing with the patched gstreamer part?

AndreV84 · 2021-01-18T19:05:50Z

I can see a variant cited here #655 (comment)

AndreV84 · 2021-01-18T19:07:55Z

yes, I tested on NX / AGX devices. the patched file should work as is. however you may try to improve it also

AndreV84 · 2021-01-18T19:08:36Z

the best improvement would be adding #include "jetson-utils/videoSource.h" library probably, but it is a separate story

radisc · 2021-01-18T19:22:33Z

Yes, that is what i tried to do and it works, because i can visualize it correctly with imshow the problem is when i feed frame_in from cv::cvtColor(frame_in, frame_in, cv::COLOR_YUV2BGR_I420); to mediapipe here:

// Wrap Mat into an ImageFrame.
    auto input_frame = absl::make_unique<mediapipe::ImageFrame>(
        mediapipe::ImageFormat::SRGB, frame_in.cols, frame_in.rows,
        mediapipe::ImageFrame::kGlDefaultAlignmentBoundary);

    cv::Mat input_frame_mat = mediapipe::formats::MatView(input_frame.get());

    frame_in.copyTo(input_frame_mat);

Then it seems mediapipe can't process it correctly because and i get a blank screen from its output

radisc · 2021-01-18T19:28:29Z

Here is another thread with a bit more detail:
link

AndreV84 · 2021-01-18T19:31:00Z

does it works as is before you start modifying the code?
does it process CSI? as long as it does it can be approached, right

AndreV84 · 2021-01-18T19:31:46Z

there is a library jetson-util
trhat coulod benefit from CUDA cv:Mat etc
it could be integrated into the code likely
you may also try looking into it

radisc · 2021-01-19T12:58:23Z

Hi @AndreV84 , this is what i've done:
This is my vanilla gstreamer pipeline
nvarguscamerasrc ! video/x-raw(memory:NVMM), width=(int)4032, height=(int)3040, format=(string)NV12, framerate=(fraction)30/1 ! nvvidconv ! video/x-raw,format=(string)BGRx ! videoconvert ! video/x-raw, format=(string)BGR ! appsink
I open it the classic way
capture.open(pipeline, cv::CAP_GSTREAMER);
and
while (grab_frames) { cv::Mat camera_frame_raw; // Capture opencv camera or video frame. capture >> camera_frame_raw; if (camera_frame_raw.empty()) break;
then i can
// Wrap Mat into an ImageFrame. auto input_frame = absl::make_unique<mediapipe::ImageFrame>( mediapipe::ImageFormat::SRGB, camera_frame_raw.cols, camera_frame_raw.rows, mediapipe::ImageFrame::kGlDefaultAlignmentBoundary); cv::Mat input_frame_mat = mediapipe::formats::MatView(input_frame.get()); camera_frame_raw.copyTo(input_frame_mat);
and this works fine
https://ibb.co/9bqFkbv

Then, to remove videoconvert i tried this:
nvarguscamerasrc ! video/x-raw(memory:NVMM), width=(int)4032, height=(int)3040, framerate=(fraction)30/1 ! nvvidconv ! video/x-raw,format=I420 ! appsink
then
cv::cvtColor(camera_frame_raw, camera_frame, cv::COLOR_YUV2BGR_I420);
from this i can imshow camera_frame correctly, lastly
auto input_frame = absl::make_unique<mediapipe::ImageFrame>( mediapipe::ImageFormat::SRGB, camera_frame_raw.cols, camera_frame_raw.rows, mediapipe::ImageFrame::kGlDefaultAlignmentBoundary); cv::Mat input_frame_mat = mediapipe::formats::MatView(input_frame.get()); cv::cvtColor(camera_frame, input_frame_mat, cv::COLOR_BGR2RGB);
The last cvtColor is not really needed but any way at this resolution all i got is a black image out of mediapipe graph.
I tried to lower the resolution (2048x1536) and i get this from the mediapipe graph:
https://ibb.co/YNVZTrz
That i believe is the very first frame of the stream on witch mediapipe keeps running the graph indefinitely
Sorry for the long post, yesterday i was home and couldn't go in with such a detail
I hope this clarify what i've done

Did you manage to include jetson_utils in bazel?

AndreV84 · 2021-02-12T13:10:16Z

@radisc
sort of
it turned out that it worked after editing manually a source file adding to there an absolute path to the missed file
after that it assembled with bazel as I remember

I tried to follow your instructions as here but i'm still getting glog errors
