hello guys.

im using jetpack 4.5.1 and cloned the jetbot repo.

when i type the docker run command: ```
sudo docker run -it -d --restart always --runtime nvidia --network host --privileged --device /dev/video* --volume /dev/bus/usb:/dev/bus/usb --volume /tmp/argus_socket:/tmp/argus_socket --privileged --name=jetbot_camera jetbot/jetbot:camera-0.4.3-32.5.0


it creates the container just fine without issue, but the container keeps restarting over and over again

and if just type the command:
docker run -ti jetbot/jetbot:camera-0.4.3-32.5.0 

i have tons of errors:

nvbuf_utils: Could not get EGL display connection0
nvarguscamerasrc sensor-mode=0 ! video/x-raw(memory:NVMM), width=816, height=616, format=(string)NV12, framerate=(fraction)21/1 ! nvvidconv ! video/x-raw, width=(int)224, height=(int)224, format=(string)BGRx ! videoconvert ! video/x-raw, format=(string)BGR ! appsink name=sink

iĀ“ve tried with jetpack 4.6, 4.5.1, jetbot 4.4, 4.3 and the same result

Could you try this for checking the camera function.

sudo docker run --net=host --runtime nvidia --rm --ipc=host -v /tmp/.X11-unix/:/tmp/.X11-unix/ -v /tmp/argus_socket:/tmp/argus_socket --cap-add SYS_PTRACE -e DISPLAY=$DISPLAY -it nvcr.io/nvidia/l4t-base:r32.5.0

with that it works:

jetbot@nano-4gb-jp441:~$ sudo docker run -dti --net=host --runtime nvidia --rm --ipc=host -v /tmp/.X11-unix/:/tmp/.X11-unix/ -v /tmp/argus_socket:/tmp/argus_socket --cap-add SYS_PTRACE -e DISPLAY=$DISPLAY -it nvcr.io/nvidia/l4t-base:r32.5.0

but with the jetbot docker camera not

here is the problem:

im trying to use the Collision Avoidance - Data Collection notebook

but everytime the kernel crashes or no camera detected

i found the issue.

sudo docker ps
CONTAINER ID        IMAGE                                COMMAND                  CREATED             STATUS              PORTS               NAMES
9c2527c4e109        jetbot/jetbot:jupyter-0.4.3-32.5.1

sudo docker exec -ti 9c2527c4e109 bash

vim /usr/local/lib/python3.6/dist-packages/jetbot-0.4.3-py3.6.egg/jetbot/camera/opencv_gst_camera.py

self.cap = cv2.VideoCapture(self._gst_str(), cv2.CAP_GSTREAMER)
self.cap = cv2.VideoCapture(0, cv2.CAP_GSTREAMER)

iĀ“ve changed the:

self._gst_str()  
for the 0

in:

vim /usr/local/lib/python3.6/dist-packages/jetbot-0.4.3-py3.6.egg/jetbot/camera/opencv_gst_camera.py

and now i can access my camera
