Gensim And Compatibility
Gensim supports any Python that's before its end-of-life:
- Old Python releases (not supported): https://devguide.python.org/devcycle/#end-of-life-branches
- Active Python releases (supported): https://devguide.python.org/#branchstatus
Current (supported) Pythons are automatically tested via Gensim's continuous integration (CI) system.
Gensim follows "semantic versioning": major.minor.bugfix, though not fanatically. Always read the release notes carefully!
To upgrade to the latest release, simply run
pip install --upgrade gensimUsers store Gensim models using Gensim's native .save() and .load() methods.
After you upgrade Gensim, your serialized model may be out-of-date: the new Gensim release may have added/removed some attributes, or made other changes.
To cut down maintenance effort, Gensim only guarantees (and automatically tests) compatibility between successive major releases. That is, a model stored in Gensim 4.X is guaranteed to load in 4.(X+1). But not necessarily in 4.(X+2), 4.(X+3), etc.
Loading older models may work too, but Gensim is an open source project run by volunteers and we cannot promise anything more.
Your other option is to re-train your model from scratch with each Gensim upgrade. This may offer additional benefits, because new version may have improved accuracy, fixed bugs etc.
