Probable mistake in module import

Quick Answer

Enable with -W all to surface ImportWarnings; check for missing __init__.py or sys.path ordering issues.

Production Risk

Low.

What this means

Raised when a probable mistake is detected in an import statement, such as a missing __init__.py or a shadowed module name. Silenced by default.

Why it happens
  1. 1Importing a package directory that lacks __init__.py in Python 2 legacy code
  2. 2A local file shadows a standard library module name

Fix

Enable and fix import path issues

Enable and fix import path issues
# Diagnose:
python -W all -c "import my_module"

# Fix shadowed names by renaming the local file
# Fix missing __init__.py by adding it to the package directory

Why this works

ImportWarning surfaces import path problems that would otherwise silently use the wrong module.
