The Python API can be installed using pip and is also included in the server installation.

Note: This limited preview version of the Python SDK is not supported for production use. The API is likely to change for the full release of Diffusion™ 6.6

Install with pip:

pip install diffusion
To install a specific version:
pip install diffusion==6.6rc1
Supported interpreters:
  • CPython 3.7.8 (or later patch release)
  • CPython 3.8.6 (or later patch release)

Future releases will be tested against additional interpreters.

We recommend using the newest available patch release.


This preview version of the Python SDK supports a limited subset of Diffusion features.

Currently it can subscribe to topics, but not create or update them. It also supports request-response messaging.

The full 6.6 version is planned to implement support for more functions.

See the API documentation for details.
