Python Install¶

pip¶

pip install doppler-dsp

No system libraries needed

The wheel bundles all native dependencies — the streaming extension statically links a vendored copy of nats.c. pip install works out of the box on Linux (x86_64, aarch64), macOS (arm64) and Windows (x64), for Python 3.9+.

Windows

The Windows wheel is the same package as on Linux and macOS, including the NATS stream layer (doppler.stream, doppler.wfm.StreamSink) and the wfmgen command, which it has carried since #1575.

Verify¶

python -c "import doppler; print(doppler.__version__)"
