AI Examples

UFRC AI Service Team created a suite of examples for computer vision and natural language processing tasks using the AI software stacks on HiPerGator. Users may copy these examples to their own space, add modifications, and follow the instructions to run these jobs on HiPerGator. They may also adapt and extend the examples for their own research projects.

Use https://support.rc.ufl.edu to submit ticket if you need help with running the examples.

Research Computing Github

We have examples available on the UF Research Computing Github.

For multinode pytorch distributed, see our pytorch distributed launch utility.
