 "title": "Cut Vision HOPE inference time on an NVIDIA GPU",
 "page_title": "How to cut Vision HOPE inference time on an NVIDIA GPU with Vision HOPE",
 "summary": "Turn on fast inference for standalone modules or prepare a full model for faster forward passes.",
 "who": "An engineer deploying a Vision HOPE model for batch image processing who needs lower latency on an NVIDIA GPU.",
 "problem": "A model loaded for training runs slower than needed for inference, and the README has separate fast paths for modules and full models.",
 "outcome": "Inference runs with fast inference enabled and the weights stay the same, so outputs match the original model within normal numerical differences.",
 "steps": [
  "Install the classification requirements with `python -m pip install -r requirements/classification.txt` and `python -m pip install --no-deps -e .`.",
  "Load the model with `create_model(\"visionhope_small\", checkpoint_path=\"weights/visionhope_small.pth\").cuda().eval()`. (inferred, check the README)",
  "Call `prepare_for_inference(model)` from `visionhope.inference.prepare` after loading the weights.",
  "Run the forward pass inside `torch.inference_mode()` and `torch.autocast(\"cuda\", dtype=torch.bfloat16)`.",
  "Keep an unprepared copy of the model if you also plan to continue training, because the preparation fuses parameters in place."
 ],
 "agent_prompt": "Using the VisionHOPE repo (PSRben/VisionHOPE), load visionhope_small.pth from weights/, call prepare_for_inference on it, and time 100 forward passes on random CUDA inputs of shape [1, 3, 224, 224] for <target hardware>. Report the average latency before and after preparation. Verify that the prepared model still returns logits shaped [1, 1000].",
