urban-worm 0.1.2

Workflow of reproducible multimodal inference for urban environment evaluation.

Urban-WORM

Introduction

Urban-WORM (Workflow Of Reproducible Multimodal Inference) is a user-friendly high-level interface that is designed for adding rich and meaningful captions for crowdsourced data with geotags using multimodal models. Urban-WORM can support the batched analysis of images and sounds for investigating urban environments at scales. The investigation may cover topics about building conditions, street appearance, people's activities, etc.

• Free software: MIT license
• Website/Documentation: https://digital-landscapes.github.io/urbanworm/

Features

• Collect geotagged data (Mapillary street views, Flickr photos, and Freesound audios) via APIs within the proximity of building footprints (or other POIs)
• Calibrate the orientation of the panorama street views to look at given locations
• Filter out personal photo using face detection
• Divide sound recording to multiple clips with given duration
• Support (batched) multiple data input with multimodal models

Installation

1 install the package

The package urban-worm can be installed with pip:

pip install urban-worm

2 Inference with llama.cpp

To run more pre-quantized models with vision capabilities, please install pre-built version of llama.cpp:

# Windows
winget install llama.cpp

# Mac and Linux
brew install llama.cpp

More information about the installation here

More GGUF models can be found at the Hugging Face pages here and here

3 Inference with Ollama client

Please make sure Ollama is installed before using urban-worm if you plan to rely on Ollama

For Linux, users can also install ollama by running in the terminal:

curl -fsSL https://ollama.com/install.sh | sh

For MacOS, users can also install ollama using brew:

brew install ollama

To install brew, run in the terminal:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Windows users should directly install the Ollama client

To install the development version from this repo:

pip install -e git+https://github.com/billbillbilly/urbanworm.git#egg=urban-worm

Usage

from urbanworm.inference.llama import InferenceOllama

data = InferenceOllama(image = 'docs/data/img_1.jpg')
system = '''
    Your answer should be based only on your observation. 
    The format of your response must include answer (yes/True or no/False), explanation (within 50 words)
'''
prompt = '''
    Is there a tree?
'''

data.llm = "hf.co/ggml-org/InternVL3-8B-Instruct-GGUF:Q8_0"
data.schema = {
    "answer": (bool, ...),
    "explanation": (str, ...)
}
data.one_inference(system=system, prompt=prompt)

More examples can be found here.

To do

v0.1.x:

• A module for collecting social media data (Flickr and Freesound)
• A method for inferencing sound recordings

v0.2.x:

• A web UI providing interactive operation and data visualization
