spatial-reasoning 0.2.1

A PyPI package for object detection using advanced vision models

Spatial Reasoning: www.spatial-reasoning.com

A powerful Python package for object detection using advanced vision and reasoning models, including OpenAI's models and Google's Gemini.

Comparison of detection results across different models - showing the superior performance of the advanced reasoning model

Features

• Multiple Detection Models:

  • Advanced Reasoning Model (OpenAI) - Reasoning model that leverages tools and other foundation models to perform object detection
  • Vanilla Reasoning Model - Directly using a reasoning model to perform object detection
  • Vision Model - GroundingDino + SAM
  • Gemini Model (Google) - Fine-tuned LMM for object detection

• Tool-Use Reasoning: Our advanced model uses innovative grid-based reasoning for precise object detection

  How the advanced reasoning model works under the hood - using grid cells for precise localization

• Simple API: One function for all your detection needs

• CLI Support: Command-line interface for quick testing

Installation

pip install spatial-reasoning

Or install from source:

git clone https://github.com/QasimWani/spatial-reasoning.git
cd spatial_reasoning
pip install -e .

Optional: Flash Attention (for better performance)

For improved performance with transformer models, you can optionally install Flash Attention:

pip install flash-attn --no-build-isolation

Note: Flash Attention requires CUDA development tools and must be compiled for your specific PyTorch/CUDA version. The package will work without it, just with slightly reduced performance.

Setup

Create a .env file in your project root:

# .env
OPENAI_API_KEY=your-openai-api-key-here
GEMINI_API_KEY=your-google-gemini-api-key-here

Quick Start

Python API

from spatial_reasoning import detect

# Detect objects in an image
result = detect(
    image_path="https://ix-cdn.b2e5.com/images/27094/27094_3063d356a3a54cc3859537fd23c5ba9d_1539205710.jpeg",  # or image-path
    object_of_interest="farthest scooter in the image",
    task_type="advanced_reasoning_model"
)

# Access results
bboxes = result['bboxs']
visualized_image = result['visualized_image']
print(f"Found {len(bboxes)} objects")

# Save the result
visualized_image.save("output.jpg")

Command Line

# Basic usage
spatial-reasoning --image-path "image.jpg" --object-of-interest "person"  # "advanced_reasoning_model" used by default

# With specific model
spatial-reasoning --image-path "image.jpg" --object-of-interest "cat" --task-type "gemini"

# From URL with custom parameters
vision-evals \
  --image-path "https://example.com/image.jpg" \
  --object-of-interest "text in image" \
  --task-type "advanced_reasoning_model" \
  --task-kwargs '{"nms_threshold": 0.7}'

Available Models

• advanced_reasoning_model (default) - Best accuracy, uses tool-use reasoning
• vanilla_reasoning_model - Faster, standard detection
• vision_model - Uses GroundingDino + (optional) SAM2 for segmentation
• gemini - Google's Gemini model
