- ## Getting Started
-
- ### Installation
-
- ```bash
- pip install dora-rs-cli
- ```
-
- <details close>
- <summary><b>Additional installation methods</b></summary>
-
- Install dora with our standalone installers, or from [crates.io](https://crates.io/crates/dora-cli):
-
- ### With cargo
-
- ```bash
- cargo install dora-cli
- ```
-
- ### With Github release for macOS and Linux
-
- ```bash
- curl --proto '=https' --tlsv1.2 -LsSf https://github.com/dora-rs/dora/releases/latest/download/dora-cli-installer.sh | sh
- ```
-
- ### With Github release for Windows
-
- ```powershell
- powershell -ExecutionPolicy ByPass -c "irm https://github.com/dora-rs/dorareleases/latest/download/dora-cli-installer.ps1 | iex"
- ```
-
- ### With Source
-
- ```bash
- git clone https://github.com/dora-rs/dora.git
- cd dora
- cargo build --release -p dora-cli
- PATH=$PATH:$(pwd)/target/release
- ```
-
- </details>
-
- ### Run
-
- - Run the yolo python example:
-
- ```bash
- ## Create a virtual environment
- uv venv --seed -p 3.11
-
- ## Install nodes dependencies of a remote graph
- dora build https://raw.githubusercontent.com/dora-rs/dora/refs/heads/main/examples/object-detection/yolo.yml --uv
-
- ## Run yolo graph
- dora run yolo.yml --uv
- ```
-
- > Make sure to have a webcam
-
- To stop your dataflow, you can use <kbd>ctrl</kbd>+<kbd>c</kbd>
-
- - To understand what is happening, you can look at the dataflow with:
-
- ```bash
- cat yolo.yml
- ```
-
- - Resulting in:
-
- ```yaml
- nodes:
- - id: camera
- build: pip install opencv-video-capture
- path: opencv-video-capture
- inputs:
- tick: dora/timer/millis/20
- outputs:
- - image
- env:
- CAPTURE_PATH: 0
- IMAGE_WIDTH: 640
- IMAGE_HEIGHT: 480
-
- - id: object-detection
- build: pip install dora-yolo
- path: dora-yolo
- inputs:
- image: camera/image
- outputs:
- - bbox
-
- - id: plot
- build: pip install dora-rerun
- path: dora-rerun
- inputs:
- image: camera/image
- boxes2d: object-detection/bbox
- ```
-
- - In the above example, we can understand that the camera is sending image to both the rerun viewer as well as a yolo model that generates bounding box that is visualized within rerun.
-
- ### Documentation
-
- The full documentation is available on [our website](https://dora-rs.ai/).
- A lot of guides are available on [this section](https://dora-rs.ai/docs/guides/) of our website.
-
- ## What is Dora? And what features does Dora offer?
-
- **D**ataflow-**O**riented **R**obotic **A**rchitecture (`dora-rs`) is a framework that makes creation of robotic applications fast and simple.
-
- `dora-rs` implements a declarative dataflow paradigm where tasks are split between nodes isolated as individual processes.
-
- The dataflow paradigm has the advantage of creating an abstraction layer that makes robotic applications modular and easily configurable.
-
- ### TCP Communication and Shared Memory
-
- Communication between nodes is handled with shared memory on a same machine and TCP on distributed machines. Our shared memory implementation tracks messages across processes and discards them when obsolete. Shared memory slots are cached to avoid new memory allocation.
-
- ### Arrow Message Format
-
- Nodes communicate with Apache Arrow Data Format.
-
- [Apache Arrow](https://github.com/apache/arrow-rs) is a universal memory format for flat and hierarchical data. The Arrow memory format supports zero-copy reads for lightning-fast data access without serialization overhead. It defines a C data interface without any build-time or link-time dependency requirement, that means that `dora-rs` has **no compilation step** beyond the native compiler of your favourite language.
-
- ### Opentelemetry
-
- dora-rs uses Opentelemetry to record all your logs, metrics and traces. This means that the data and telemetry can be linked using a shared abstraction.
-
- [Opentelemetry](https://opentelemetry.io/) is an open source observability standard that makes dora-rs telemetry collectable by most backends such as elasticsearch, prometheus, Datadog...
-
- Opentelemetry is language independent, backend agnostic, and easily collect distributed data, making it perfect for dora-rs applications.
-
- ### ROS2 Bridge
-
- **Note**: this feature is marked as unstable.
-
- - Compilation Free Message passing to ROS 2
- - Automatic conversion ROS 2 Message <-> Arrow Array
-
- ```python
- import pyarrow as pa
-
- # Configuration Boilerplate...
- turtle_twist_writer = ...
-
- ## Arrow Based ROS2 Twist Message
- ## which does not require ROS2 import
- message = pa.array([{
- "linear": {
- "x": 1,
- },
- "angular": {
- "z": 1
- },
- }])
-
- turtle_twist_writer.publish(message)
- ```
-
- > You might want to use ChatGPT to write the Arrow Formatting: https://chat.openai.com/share/4eec1c6d-dbd2-46dc-b6cd-310d2895ba15
