Report #104508

[bug\_fix] ImportError: cannot import name 'cached\_property' from 'functools' \(unknown location\)

Use \`from functools import cached\_property\` only in Python 3.8\+. For earlier versions, install \`backports.cached\_property\` and import from there, or use \`@property\` and manual caching.

Journey Context:
Developer wrote code using \`@functools.cached\_property\` on a server running Python 3.7. The import failed. After checking the Python version, they realized cached\_property was added in 3.8. Root cause: using a Python version-specific feature without version guard. Fix works by either upgrading Python or using a backport package.

environment: Debian 10, Python 3.7, production server, code deployed via git. · tags: importerror cached_property python-version compatibility functools · source: swarm · provenance: Python docs: https://docs.python.org/3/library/functools.html\#functools.cached\_property
