No Module named v4l2


I have a jetson nano with jetpack 4.4 and I am following this installation path:

I use python 3

I have no errors untill I do the “sudo pip3 install v4l2” - the installation works but when I run “python -d 0” I get “Importerror, no module named v4l2”

However if I go to


and start a python prompt, and writes “import v4l2” it works fine (this does not work when I am in “MIPI_Camera/Jetson/Jetvariety/example” - then I just get “Importerror, no module named v4l2”).

What shall I do to be able to import v4l2 from all directorys and not only from /usr/local/lib/python3.6/dist-packages?
