im trying to install some facemask detection demo (the one made by Nvidia) and i get this error

nx@nx-desktop:~/Downloads/face-mask-detection-master/ds_configs$ deepstream-app -c deepstream_app_source1_camera_masknet_gpu.txt

hope you can help me thanks!

• How to reproduce the issue ? (This is for bugs. Including which sample app is using, the configuration files content, the command line used and other details for reproducing)
while trying to run
nx@nx-desktop:~/Downloads/face-mask-detection-master/ds_configs$ deepstream-app -c deepstream_app_source1_video_masknet_gpu.txt

• Requirement details( This is for new requirement. Including the module name-for which plugin or for which sample application, the function description) im trying to install and run the sample demo

Hi,

Error: Could not parse TLT encoded model file path

The error indicates that deepstream-app cannot find the file correctly.
Could you check if the file exists first?

Thanks.

4

No it doesnt and I don’t knownwhere to find it, shall i download it or is it generated?

5

or do you know what can i do to get that file?

6

Hi,

The model should generate in the training stage.
Have you applied the training steps shared in this section first?

Thanks.

Yes i did

for transforming into kitty i did this

python3 data2kitti.py --kaggle-dataset-path “/home/nx/Downloads/face-mask-detection-master”
–mafa-dataset-path “/home/nx/Downloads/face-mask-detection-master/face-mask-detection-data/MAFA Dataset”
–fddb-dataset-path “/home/nx/Downloads/face-mask-detection-master”
–widerface-dataset-path “/home/nx/Downloads/face-mask-detection-master/face-mask-detection-data/Wider Face Dataset”
–kitti-base-path “/home/nx/Downloads/face-mask-detection-master/face-mask-detection”
–category-limit 6000 \ # i used this numbers for no reason if you have a
recommendation please let me know
–tlt-input-dims_width 500
–tlt-input-dims_height 500
–train

9

after that i dont know where to find “tlt-encoded-model” , model-engine-file, int8-calib-file

10

Or is there any video tutorial?

Hi,

Do you run TLT training on the XavierNX?
Please noted that training with TLT is only on x86 with NVIDIA GPU such as a V100.

For more TLT document, please check this page:

Thanks.
