I'm interested in playing with this, but I'm not interested in paying $3000 for a high-end nVidia NPU. It seems to be in principle possible to split the task into smaller subtasks that could be distributed to a Beowulf-style Pi cluster. Several enclosures exist that let you connect multiple Compute Modules over a high-speed bus, I hear.
I have minimal experience with Raspberry Pi (not zero, but minimal). I have none with setting up Beowulf clusters, and none with decomposing machine learning tasks and distributing them among processors. Thus, I wonder if there might be an existing project I could learn from and maybe even eventually contribute to, even if only as a tester.
Thanks.
