@dineshp Thanks very much. I got an error when I run the command "sudo modprobe bcm2835-v4l2". root@01:/ai/trn-pytorch# root@ai-k4-u18-c92n742-01:/ai/trn-pytorch# sudo modprobe bcm2835-v4l2 -bash: root@01:/ai/trn-pytorch#: No such file or directory cm2835-v4l2 not found in directory /lib/modules/4.15.0-49-genericroot@ai-k4-u18-c92n742-01:/ai/trn-pytorch# modprobe: FATAL: Module bcm2835-v4l2 not found in directory /lib/modules/4.15.0-49-generic

I have no "raspberry pi", I use the laptop remote(SSH) call Ubuntu18.04 server, how to use the laptop camera connection to webcam.

If you don't have a webcam you can interact with you are out of luck
