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


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?


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

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


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