reactor-runtime 1.4.3

Reactor runtime with public model API

Reactor Runtime

A Python runtime for building real-time video processing models. This runtime abstracts all the techincal implementations of real-time networking, allowing researchers and models developers to run their model focusing only on the ML code.

You can think of this similarly to the way you write Telegram/Discord applications or bots using SDKs. You don't have to worry about the networking and the protocols of the medium. Instead, you can put all your effort in writing your application code, which in this case is ML code.

Installation

pip install reactor-runtime

Development Setup

Proto dependencies are fetched from the private reactor-team/reactor-proto repo. The version is defined in pyproject.toml under [tool.reactor-proto].

# Set your GitHub token (required for private repo access)
export GH_TOKEN=your_github_token

# Install with proto dependencies
make install

# Or fetch protos separately
make proto

The proto wheel is downloaded to generated/ (gitignored). Once installed, proto types are available via:

from api import reactor_pb2
from api.types import api_types_pb2, base_pb2

Publishing

make publish

The publish script performs two key transformations before building:

1. Obfuscation

All files and directories prefixed with _ are stripped from the published package (except __init__.py and __pycache__). This allows you to keep private/internal code in the repository that won't be shipped to users.

Example: A _cloud/ directory or _internal.py file will exist in the repo for development but won't appear in the PyPI package.

2. Proto Vendoring

The script uses AST analysis to scan all remaining (public) source files and identifies which api.* modules are actually imported. Only those specific proto files are copied into the published package.

This means:

• Users don't need access to the private reactor-proto repo
• The published package is self-contained with proto types bundled
• Only the protos actually used by public code are included, keeping the package minimal

Prerequisite: Run make proto before publishing to ensure proto types are installed locally for vendoring.
