https://youtu.be/xL1QuxN_Aqcjust like topic, when ever I try to run the model block in jupyter lab, putty crashes. tried mobax, changed the internet also, nothing help.
Hi @qfur890416, did you mount extra swap memory and disable ZRAM per the DLI course instructions?
Can you keep an eye on the memory usage by running
sudo tegrastats in a separate terminal? If you are low on memory, you can also run
sudo systemctl set-default multi-user.target and reboot.
I have one 2060 in my computer, is it possible for me run on PC?
Hi @qfur890416, from your tegrastats output, it doesn’t appear that you have swap memory mounted. Please follow these directions to mount swap:
Also, your idle memory usage appears to be a bit high. Please make sure that you have the desktop shutdown by running the following command and then rebooting your board:
sudo systemctl set-default multi-user.target
the whole model is set, but there’s another problem.

From your tegrastats output, it still doesn’t appear that you have swap memory mounted. Please follow these directions to mount swap:
it says that i don’t have the rights
Instead of running the command
/mnt/4GB.swap none swap sw 0 0, you need to add to the end of
/etc/fstab file and reboot. You can edit
/etc/fstab with vi/vim or nano text editor like:
sudo vi /etc/fstab
how do i save the edit file
maybe I’m not clear enough, I’ve used “i” to enter ‘/mnt/4GB.swap none swap sw 0 0’ in ‘/etc/fstab’ and “esc” to quit edit mode, so then I have to use “:wq” to leave?
got stuck here, how do i exit？
@qfur890416 you may just want to install/use nano editor - it is easier to use.
You can run:
sudo apt-get update sudo apt-get install nano sudo nano /etc/fstab
Ok i have solved the problem and edit the file, however I can’t link to the jupyter lab now.

@qfur890416 did you reboot your Nano and restart the container?
