x2vec, Towhee is all you need!

ENGLISH | 中文文档

 

Towhee makes it easy to build neural data processing pipelines for AI applications. We provide hundreds of models, algorithms, and transformations that can be used as standard pipeline building blocks. You can use Towhee's Pythonic API to build a prototype of your pipeline and automatically optimize it for production-ready environments.

🎨 Various Modalities: Towhee supports data processing on a variety of modalities, including images, videos, text, audio, molecular structures, etc.

🎓 SOTA Models: Towhee provides SOTA models across 5 fields (CV, NLP, Multimodal, Audio, Medical), 15 tasks, and 140+ model architectures. These include BERT, CLIP, ViT, SwinTransformer, MAE, and data2vec, all pretrained and ready to use.

📦 Data Processing: Towhee also provides traditional methods alongside neural network models to help you build practical data processing pipelines. We have a rich pool of operators available, such as video decoding, audio slicing, frame sampling, feature vector dimension reduction, ensembling, and database operations.

🐍 Pythonic API: Towhee includes a Pythonic method-chaining API for describing custom data processing pipelines. We also support schemas, which makes processing unstructured data as easy as handling tabular data.

Getting started

Towhee requires Python 3.6+. You can install Towhee via pip:

pip install towhee towhee.models

If you run into any pip-related install problems, please try to upgrade pip with pip install -U pip.

Try your first Towhee pipeline. For example, create a CLIP-based cross modal retrieval pipeline with only 15 lines of code.

import towhee

# create image embeddings and build index
(
    towhee.glob['file_name']('./*.png')
          .image_decode['file_name', 'img']()
          .image_text_embedding.clip['img', 'vec'](model_name='clip_vit_b32', modality='image')
          .tensor_normalize['vec','vec']()
          .to_faiss[('file_name', 'vec')](findex='./index.bin')
)

# search image by text
results = (
    towhee.dc['text'](['puppy Corgi'])
          .image_text_embedding.clip['text', 'vec'](model_name='clip_vit_b32', modality='text')
          .tensor_normalize['vec', 'vec']()
          .faiss_search['vec', 'results'](findex='./index.bin', k=3)
          .select['text', 'results']()
)

Core Concepts

Towhee is composed of four main building blocks - Operators, Pipelines, DataCollection API and Engine.

• Operators: An operator is a single building block of a neural data processing pipeline. Different implementations of operators are categorized by tasks, with each task having a standard interface. An operator can be a deep learning model, a data processing method, or a Python function.

• Pipelines: A pipeline is composed of several operators interconnected in the form of a DAG (directed acyclic graph). This DAG can direct complex functionalities, such as embedding feature extraction, data tagging, and cross modal data analysis.

• DataCollection API: A Pythonic and method-chaining style API for building custom pipelines. A pipeline defined by the DataColltion API can be run locally on a laptop for fast prototyping and then be converted to a docker image, with end-to-end optimizations, for production-ready environments.

• Engine: The engine sits at Towhee's core. Given a pipeline, the engine will drive dataflow among individual operators, schedule tasks, and monitor compute resource usage (CPU/GPU/etc). We provide a basic engine within Towhee to run pipelines on a single-instance machine and a Triton-based engine for docker containers.
