YoloGemma

YoloGemma is a project showcasing the capabilities of Vision-Language models in performing computer vision tasks such as object detection and segmentation. At the heart of this experiment lies PaliGemma, a state-of-the-art model that bridges the gap between Language and Vision. Through YoloGemma, we aim to explore whether Vision-Language models can match conventional methods of computer vision.

Outputs

YoloGemma generates outputs by processing images and videos to identify and segment objects within them. The results are visualized as annotated images or videos, highlighting detected objects with bounding boxes or segmentation masks.

Installation

To get started with YoloGemma, follow these simple installation steps:

1. Clone the repository:

   git clone https://github.com/your-username/YoloGemma.git
   cd YoloGemma

2. Install the required dependencies:

   conda create -n YoloGemma-venv python=3.10
   conda activate YoloGemma-venv
   pip install -e .

How to Run

Model Download

You can download the model by running the following command:

python download.py

This command will download and quantize the model.

YoloGemma provides three main scripts to facilitate various tasks. Below are instructions on how to run each script:

Main Script for Object Detection

python main.py --prompt "Detect 4 people" --vid_path ./people.mp4 --vid_start 1 --vid_end 12 --max_new_tokens 10

Command Line Arguments

• --prompt (type: str, default: "detect cat"): The prompt specifying what to detect in the video.
• --vid_path (type: str, default: ""): The path to the input MP4 video file.
• --vid_start (type: int, default: 0): The start time in seconds where the detection should begin.
• --vid_end (type: int, default: 10): The end time in seconds where the detection should stop.
• --max_new_tokens (type: int, default: 15): Maximum number of new tokens.

Additional Parameters

• --interactive (action: store_true): Launch the application in interactive mode.
• --top_k (type: int, default: 200): Top-k sampling for generating new tokens.
• --temperature (type: float, default: 0.8): Sampling temperature.
• --checkpoint_path (type: Path, default: Path("checkpoints/google/paligemma-3b-mix-224/modelint8.pth")): Path to the model checkpoint file.
• --compile (action: store_true, default: True): Whether to compile the model.
• --compile_prefill (action: store_true): Whether to compile the prefill for improved performance.
• --profile (type: Path, default: None): Path to the profile.
• --speculate_k (type: int, default: 5): Speculative execution depth.
• --draft_checkpoint_path (type: Path, default: None): Path to the draft checkpoint.
• --device (type: str, default: "cuda"): Device to use for running the model (e.g., "cuda" for GPU).

Example

python main.py --prompt "Detect 4 people" --vid_path ./people.mp4 --vid_start 1 --vid_end 12 --max_new_tokens 10

This command will start the detection process for the prompt "Detect 4 people" on the video located at ./people.mp4, beginning at 1 second and ending at 12 seconds into the video. It will use a maximum of 10 new tokens during processing.

Gradio Interface (Coming Soon)

python demo.py

This command will launch a Gradio interface, providing an interactive web application to perform object detection and segmentation.

Troubleshooting

If you encounter any issues, please ensure that:

• The video file path is correct and the file is accessible.
• The required dependencies are installed.
• Your system has the necessary hardware (e.g., a compatible GPU if using CUDA).

For further assistance, please refer to the project's issues page or contact the maintainers.
