Pipeless is an open-source framework that takes care of everything you need to develop and deploy computer vision applications in just minutes. That includes code parallelization, multimedia pipelines, memory management, model inference, multi-stream management, and more. Pipeless allows you to ship applications that work in real-time in minutes instead of weeks/months.

Pipeless is inspired by modern serverless technologies. You provide some functions and Pipeless takes care of executing them for new video frames and everything involved.

With Pipeless you create self-contained boxes that we call "stages". Each stage is a micro pipeline that performs a specific task. Then, you can combine stages dynamically per stream, allowing you to process each stream with a different pipeline without changing your code and without restarting the program. To create a stage you simply provide a pre-process function, a model and a post-process function.

You can load industry-standard models, such as YOLO, or custom models in one of the supported inference runtimes just by providing a URL. Pipeless ships some of the most popular inference runtimes, such as the ONNX Runtime, allowing you to run inference with high performance on CPU or GPU out-of-the-box.

You can deploy your Pipeless and your applications to edge and IoT devices or to the cloud. There are several tools for the deployment, including container images.

The following is a non-exhaustive set of relevant features that Pipeless includes:

  • Multi-stream support: process several streams at the same time.
  • Dynamic stream configuration: add, edit, and remove streams on the fly via a CLI or REST API (more adapters to come).
  • Multi-language support: you can Write your hooks in several languages, including Python.
  • Dynamic processing steps: you can add any number of steps to your stream processing, and even modify those steps dynamically on a per-stream basis.
  • Built-in restart policies: Forget about dealing with connection errors, cameras that fail, etc. You can easily specify restart policies per stream that handle those situations automatially.
  • Highly parallelized: do not worry about multi-threading and/or multi-processing, Pipeless takes care of that for you.
  • Several inference runtimes supported: Provide a model and select one of the supported inference runtimes to run it out-of-the-box in CPU or GPUs. We support CUDA, TensorRT, OpenVINO, CoreML, and more to come.
  • Well-defined project structure and highly reusable code: Pipeless uses the file system structure to load processing stages and hooks, helping you organize the code in highly reusable boxes. Each stage is a directory, each hook is defined on its own file.

Requirements ☝️

  • Python. Pre-built binaries are linked to Python 3.10 in Linux amd64, 3.8 in Linux arm64, and 3.12 in macOS. If you have a different Python version, provide the --build flag to the install script to build from source so Pipeless links to your installed Python version (or update your version and use a pre-built binary, which is simpler).
  • Gstreamer 1.20.3. Verify with gst-launch-1.0 --gst-version. Installation instructions here

Installation 🛠️

curl | bash

Using docker

Instead of installing locally, you can alternatively use docker and save the time of installing dependencies:

docker run miguelaeh/pipeless --help

To use it with CUDA:

docker run miguelaeh/pipeless:latest-cuda --help

To use with TensorRT use:

docker run miguelaeh/pipeless:latest-tensorrt --help

Find the whole container documentation here.

Getting Started 🚀

Init a project:

pipeless init my_project --template scaffold
cd my_project

Start Pipeless:

pipeless start --stages-dir .

Provide a stream:

pipeless add stream --input-uri "" --output-uri "screen" --frame-path "my-stage"

The code generated is an empty template that scafold a stage so it will do nothing. Please go to the examples to complete that stage.

You can also use the interactive shell to create the project:
