Gaze Demo for Jetson/L4T - Xavier AGX (L4T R32.4.2) Not Working


Followed the instructions here: NVIDIA NGC

Jetson Xavier AGX in version L4T 32.4.2 JetPack 4.4 Developer Preview (JetPack SDK 4.4 DP Archive | NVIDIA Developer)

Downloaded Docker container:

sudo docker pull

Tried running the container:

sudo xhost +si:localuser:root
sudo docker run --runtime nvidia -it --rm --network host -e DISPLAY=$DISPLAY -v /tmp/.X11-unix/:/tmp/.X11-unix python3 /videos/gaze_video.mp4 --loop --codec=h264

Get the following errors:

A window pops up with no content in it, and crashes here. The following error msg is printed:

coreReadArchive.cpp (38) - Serialization Error in verifyHeader: 0 (Version tag does not match)
INVALID_STATE: std::exception
INVALID_CONFIG: Deserialize the cuda engine failed.
Assertion fail in file 'trtNet.cpp' line 146: _engine is null

  what():  std::exception

Tried running with the video included in the docker container and with a personal video. Not working with either of them.
