I use pip-compile in the pip-tools package:

Keep your high-level dependencies in requirements.in.

Create a virtual environment using venv.

Run `pip-compile resolver=backtracking`. It autogenerates a requirements.txt file with all dependencies and sub-dependencies and their versions. This essentially acts as a lock file from other languages/frameworks.

Install from the autogenerated requirements.txt file in the venv virtual environment.

If a dependency changes, change in requirements.in, recompile the .txt file, and reinstall.

This is new for me. I used `pip freeze > requirements.txt`
