[bug\_fix] ImportError: attempted relative import beyond top-level package

Use absolute imports \(e.g., 'from mypackage import module'\) instead of relative imports \(e.g., 'from .. import module'\), or run the script as a module with 'python -m mypackage.script' instead of 'python script.py'.

Journey Context:
A developer created a package structure with subpackages and tried to run a script directly with 'python subpackage/module.py'. The script used relative imports like 'from .. import something', which failed because the script's \_\_name\_\_ is '\_\_main\_\_' and Python cannot determine the package hierarchy. The fix: either change to absolute imports, or run the script as a module using 'python -m mypackage.subpackage.module' from the parent directory. Root cause: relative imports rely on the module's \_\_package\_\_ attribute, which is not set when running a file directly.
