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+.

What the Windows wheel leaves out

The NATS stream layer is not ported to Windows yet, so the Windows wheel has no doppler.stream, no doppler.wfm.StreamSink and no wfmgen command (it prints that it is not available on this platform). Everything else, including doppler.wfm.Composer, Writer and Reader, is the same as on Linux and macOS. Tracked on #1364.

Verify¶

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