Failed to create capturesession problem with jetson nano csi camera ( now i have no cameras available )

[aliamrrr]

Hello , I recently had no space left and uninstalled docker image from dusty nv ( jetson-inference ) when I run my code I have this error .

Is it related to the doker because when I reinstall its not working . Please i need a solution !
working with jetson nano

Hi @aliamrrr , it cannot find any MIPI CSI camera attached - are you in fact trying to use CSI camera? It will try that by default, unless you specify V4L2, video stream, video file, or directory of images (see here)

Are you now running this outside of container, or inside container still? When using MIPI CSI camera, it is always a good idea to try nvgstcapture-1.0 program first. This will confirm that you MIPI CSI camera is indeed connected and functioning properly, then you can try it in jetson-inference.

Thanks for the anwer
Yes m using csi camera
I’m new to this so I will explain , in fact it was working , one day there was no space left in the device so it cant boot , I removed the jetson-inference dokcer image ( with docker rmi id …) , when It worked and I tested my code , it said failed to create capturesession(). I tried to re connect the camera and now its saying no cameras available . So this gst-launch-1.0 nvarguscamerasrc ! videoconvert ! fakesink is not working , ls /dev/video* says no such file or directory althought the camera is connected . When I re run the docker image I didnt work and I have no space left also

Please tell me the steps i can follow , ( when you say docker container are you talking about jetson-inference repo no ? )

Hi @aliamrrr, until you can get nvgstcapture-1.0 to recognize your camera, jetson-inference won't find it either (regardless of using container or not). You might check that the device is still operational. If you still have issues debugging the camera itself, I recommend to post to the Jetson forums for hardware help:

Sorry to not be of more assistant with the camera hardware directly.
