Install packages to sd card

How should i install the packages to sd card. Jetson TX2 memory is full and i can’t do anything.

For example install pytorch and want to object detection and download datasets that pytorch wants to train

Re-training SSD-Mobilenet
Collecting your own Detection Datasets

but warns of insufficient memory.

And when i’m trying to install jetson inference to SD Card, it is installed but downloading models screen does not appear.

How should i download and install any package on an external device like SD CARD or HARD Disk.
