sarutak opened a new pull request #7099: [AIRFLOW-6507] Replace the use of impl.load_source with another solution. URL: https://github.com/apache/airflow/pull/7099 As of Python 3.4, impl module will be deprecated and recommended to use importlib. Almost all the part of code in Airflow uses importlib except for impl.load_source in models/dagbag.py. This change propose a solution that use `importlib.SourceFileLoader`. I didn't add new test-case because existing test-cases in `TestDagBag` covers. --- Issue link: WILL BE INSERTED BY [boring-cyborg](https://github.com/kaxil/boring-cyborg) - [x] Description above provides context of the change - [x] Commit message/PR title starts with `[AIRFLOW-NNNN]`.
