# PILA Trains on Screen Input to Play PolyTrack > Source: > Published: 2026-06-28 17:00:14+00:00 End-to-end imitation learning from raw screen pixels is a low-friction prototyping path for perception-to-action agents: no simulator instrumentation, no reward engineering, just human demonstrations mapped to actions. Developer tryfonaskam demonstrated this concretely with PILA (PolyTrack Imitation Learning AI), an open-source agent that learns to drive the browser racing game PolyTrack by observing screen captures and recorded human keyboard inputs. Implemented in PyTorch (Python 3.11), the pipeline records player controls alongside corresponding game frames, trains a supervised neural network on those state-action pairs, then runs real-time inference to issue keyboard commands from live frames. Released under Apache 2.0 on GitHub. Reported by Hackaday on June 28, 2026. For practitioners, PILA is a useful educational baseline that surfaces the practical engineering work of synchronizing frame capture with labeled actions and replaying inputs - details papers routinely omit.
