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

Closed AndreV84 closed 4 years ago

AndreV84 commented 4 years ago

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: https://github.com/google/mediapipe/issues/304. For GPU support: https://github.com/google/mediapipe/issues/305

AndreV84 commented 4 years ago

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 commented 4 years ago

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 \

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: https://github.com/google/mediapipe/issues/200. If you are looking for some example code, please take a look at https://github.com/google/mediapipe/issues/200#issuecomment-599971551.

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

mcclanahoochie commented 4 years ago

https://storage.googleapis.com/media-001/output.mp4?authuser=0

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 commented 4 years ago

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 commented 4 years ago

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

jiuqiant commented 4 years ago

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 commented 4 years ago

@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

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?

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?

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;

I mentioned an approach to get landmarks data in https://github.com/google/mediapipe/issues/655#issuecomment-622169228. 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.

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:

Yes, the current example code only outputs images. If you plan to retrieve detection as well as landmarks data from a MediaPipe graph, it's necessary to modify the main file to observe the detection and/or landmark output stream. The combination of https://gist.github.com/mgyong/7353474eb3e57ba95621632af274911a and https://gist.github.com/mgyong/be027a075a5e7b082c566a78c3bc0d90 is the way to do this.

Thank you for sharing

mgyong commented 4 years ago

@AndreV84 We would like to get your help to document step by step in a .md file how to get MediaPipe examples to run on Nvidia Jetson so that we can include it as part of our official documentation to help other users. If you are willing, put the .md file in your public github repo and share link in this issue.

AndreV84 commented 4 years ago

@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 commented 4 years ago

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

AndreV84 commented 4 years ago

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

mgyong commented 4 years ago

@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)

AndreV84 commented 4 years ago

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

AndreV84 commented 4 years ago

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>

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 commented 3 years ago

@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

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 commented 3 years ago

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 commented 3 years ago

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 commented 3 years ago

the file has 


    cv::cvtColor(camera_frame_raw, camera_frame, cv::COLOR_BGR2RGB);
AndreV84 commented 3 years ago

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

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 commented 3 years ago

I can see a variant cited here https://github.com/google/mediapipe/issues/655#issuecomment-762369573
