Jetson nano 2GB freezes after hit "Train" on the thumb up/down exercise in Image Classification project

The training should work on Nano 2GB for things like the DLI course, JetBot, and Hello AI World.

Can you try the suggestions from this post? https://forums.developer.nvidia.com/t/camera-freezes-in-image-classification/158686/9

Also, if you are using MIPI CSI camera, you may want to switch to using USB webcam for the DLI course, like Logitech C920/C270 or similar.
