Cloudflare Pages static PyPI simple index
A static repository of prebuilt CycloneDDS Python wheels for aarch64 Linux.
The official cyclonedds-python project publishes relatively few prebuilt binaries. On Unitree devices, installation often falls back to building CycloneDDS from source first. This site provides a static PyPI Simple Repository API endpoint for those wheels.
Build context
The upstream cyclonedds-python releases have limited prebuilt binary coverage, especially for Linux aarch64 robot images. Without a matching wheel, installation commonly requires compiling the CycloneDDS C library and Python bindings from source.
| Device / image | Python version | CycloneDDS versions |
|---|---|---|
| Thor, JetPack 7.0, L4T 38.2.1, Unitree factory image | CPython 3.12 (cp312) | 0.10.2, 0.10.5*, 11.0.1 |
| Orin NX, JetPack 5.1.1, L4T 35.3.1, Unitree factory image | CPython 3.8 (cp38) | 0.10.2, 0.10.5 |
* marks a tested version.
If this index does not have a wheel for your Python, CycloneDDS, or device image combination, run build_cyclonedds_wheels.sh on the target environment.
Install
Keep PyPI as the primary index and add this wheel index:
pip install --extra-index-url https://pypi.cyoahs.dev/simple cycloneddsInstall only from this index:
pip install --index-url https://pypi.cyoahs.dev/simple cycloneddsOn Python versions newer than 3.10, unitree_sdk2_python with cyclonedds==0.10.2 may hit a buffer overflow around ChannelFactoryInitialize; see unitreerobotics/unitree_sdk2_python#90.
Install unitree_sdk2_python first, then override CycloneDDS with a newer wheel from this index:
pip install --upgrade --extra-index-url https://pypi.cyoahs.dev/simple cyclonedds==0.10.5Maintain
build_cyclonedds_wheels.sh builds the CycloneDDS C library, builds Python wheels, runs auditwheel, and writes versioned outputs under wheelhouse.
./build_cyclonedds_wheels.sh 0.10.2 0.10.5 11.0.1After updating wheels, place files under public/packages and keep the static index pages under public/simple in sync.
