Using 256GB MicroSd Card with Jetson Nano

I have recently purchased a new Strontium Nitro A1 256GB micro SD card for my Jetson Nano.
I would like to train an image recognition and classification model using 1000s of self-collected images on different categories of images. Can someone guide me on how to get started, with this?

I am new to Jetson Nano, I know Python programming.

Hi anand.m.arora,

Please refer to to get start.
