Stage 2 starts from the ActivityNet Stage 1 checkpoint and optimizes iterative retrieval and temporal grounding behavior with the VideoSearch-R1 training pipeline.

Usage

Use with the VideoSearch-R1 codebase:

bash scripts/data_construct/download_preextracted_data.bash activitynet
EVAL_GPUS=0 bash scripts/inference/inference.bash activitynet --checkpoint VideoSearchR1/activitynet-stage2
