Hi, I meet several issues about ”deepstream-transfer-learning-app“

  1. can’t print information on terminal, tried “g_print, std::cout, printf”, none of them works
  2. can’ t change on screen display. I changed “diaplay_meta” in “after_pgie_image_meta_save()” and “overlay_graphics()” , but nothing changed on screen

so, how to solve them?

  1. can’t print information on terminal, tried “g_print, std::cout, printf”, none of them works
    –>please use g_print in gstreamer based app.
  2. can’ t change on screen display. I changed “diaplay_meta” in “after_pgie_image_meta_save()” and “overlay_graphics()” , but nothing changed on screen
    → What kind of info you want to change?

  1. I use them in “deepstream_transfer_learning_app_main.cpp”. besides ‘g_print’, ‘std::cout’ and ‘printf’ not work too. can you check the reason?
  1. for example, in “deepstream_transfer_learning_app_main.cpp → overlay_graphics( )”, I change offset, font_color, and test_bg_clr, but not work on screen.
    besides, I change these in “deepstream-app/deepstream_app_main.c → overlay_graphics( )” still not work.

    display_meta->text_params[0].y_offset = 200;
    display_meta->text_params[0].x_offset = 200;
    display_meta->text_params[0].font_params.font_color = (NvOSD_ColorParams) {
            0, 1, 0, 0.6};
    display_meta->text_params[0].font_params.font_size =
            appCtx->config.osd_config.text_size * 1.5;
    char serif[] = "Serif";
    display_meta->text_params[0].font_params.font_name = serif;
    display_meta->text_params[0].set_bg_clr = 1;
    display_meta->text_params[0].text_bg_clr = (NvOSD_ColorParams) {
            0, 0, 0, 0.2};

I even replace ‘overlay_graphics( )’ by the following, but “source:rtsp:…” is still displayed on screen.

static gboolean
overlay_graphics(AppCtx *appCtx, GstBuffer *buf,
                 NvDsBatchMeta *batch_meta, guint index) {
    return TRUE;
}

Please share your build, run steps and how to view the log output.
The issue should be caused by your operation steps, so please detail them.

waht I do is:

cd sources/apps/sample_apps/deepstream-transfer-learning-app
make
cd configs
mkdir output
deepstream-transfer-learning-app -c ds_transfer_learning_app_example.txt

by the way, I alose tried these steps in: “/opt/nvidia/deepstream/deepstream-5.1”. but it not works too

can you tell me which part is wrong?

7

can you please make sure it works without this copy?

8

I tried in

/opt/nvidia/deepstream/deepstream-5.1
it not works too

9

to simply test, I just add this in main()


int main(int argc, char *argv[]) {
    GOptionContext *ctx = nullptr;
    GOptionGroup *group = nullptr;
    GError *error = nullptr;
    guint i;

    std::cout<<"======="<< std::endl;
    std::cout<<"======="<< std::endl;
    g_print("-------\n");
    g_print("-------\n");

... ... ...
... ... ...

but I didn’t see these printed

10

maybe I find the problem
I “make clean” everyone where I build “deepstream-transfer-learning-app”. then I change app name in Makefile:
APP:= deepstream-tf-test
after that, I do these:

make 
cd configs
deepstream-tf-test -c ds_transfer_learning_app_example.txt

it shows this:

deepstream-tf-test: command not found

then I tried

deepstream-transfer-learning-app -c ds_transfer_learning_app_example.txt

it still works!

so, can you tell me:
1 how to remove “deepstream-transfer-learning-app” clearly ?
2. why “APP:= deepstream-tf-test” does not work ?

11

after you change to “APP:= deepstream-tf-test”, why is there still deepstream-transfer-learning?

12

that’s what I want to know

13

this seems not matter what I changd in “deepstream_transfer_learning_app_main.cpp". when I run “deepstream-transfer-learning-app …”, it uses some app else, but doesn’t use what I make

14

so, can you tell me:
1 how to remove “deepstream-transfer-learning-app” clearly ?
2. why “APP:= deepstream-tf-test” does not work ?

15

please share log below

make clean
make -Bn

you need to run make install to copy deepstream-tf-test to $(APP_INSTALL_DIR) .
Please try to read the Makefile

thanks! problem solved
