Summary:
This makes it a proper python package, therefore `ModuleFinder` will parse dependencies from this module. (see https://docs.python.org/3/tutorial/modules.html )
As result, changes to `torch/testing/_internal/common_quantization` or `test/quantization/*.py` would be considered affecting `test_quantization.py`.
