Common errors

error ModuleNotFoundError: No module named 'ipyflow' ↓

cause Installed ipyflow-core but trying to import 'ipyflow'.

fix

Install 'ipyflow' jupyterlab extension or use 'from ipyflow.core import ...'

error ImportError: cannot import name 'FlowManager' from 'ipyflow' ↓

cause Incorrect import path; FlowManager is in ipyflow-core, not ipyflow.

fix

Install ipyflow-core and use 'from ipyflow.core import FlowManager'

gotcha Do not import from 'ipyflow' directly for core functionality; use 'ipyflow-core' instead. ↓

fix Use 'from ipyflow.core import ...'

breaking Reactive behavior is enabled by default since v0.0.193; explicit opt-out required if not desired. ↓

fix Set 'FlowManager(reactive=False)' to opt out.

deprecated The 'cousin_reactivity' flag is deprecated; cousin reactivity is now the default. ↓

fix Remove the flag; if you need to disable, use 'flow_manager.cousin_reactivity = False'.
