Report #99128

[bug\_fix] AttributeError: module 'collections' has no attribute 'Callable'

Replace collections.Callable with collections.abc.Callable. If the offending code is in a third-party library, upgrade the library to a Python 3.10\+ compatible release.

Journey Context:
You run a legacy CLI tool on Python 3.10 and it crashes inside a third-party library at collections.Callable. The alias was deprecated since Python 3.3 and removed in 3.10. Patching the import to collections.abc.Callable, or upgrading the library, restores the behavior.

environment: Python 3.10\+ with legacy code or older third-party libraries · tags: attributeerror collections collections.abc callable python-3.10 · source: swarm · provenance: https://docs.python.org/3/library/collections.abc.html
