After the environment of Jetson nano is installed, debug the python program with Jupiter notebook. After starting
$Jupiter notebook
, a continuous prompt appears in terminal
error: can’t initialize nvrm channel
after query, it is related to the camera input on the nano, but the program does not use the camera. Jupyter can work normally, but it will affect the viewing of debugging information.

Solution:
to bypass this problem, open the chromium browser before starting jupyter, and then jupyter will open the page in the existing browser, so the above error will not appear in terminal.
