Speed up dependency extraction for Python projects.

[jianzs]

Currently, the slow deduction speed is mainly due to the slow dependency extraction, which presents several issues:

1. Whenever there's a change in one part of the code, almost all business sections need to reinstall dependencies.
2. Even if dependencies remain unchanged, any code modification requires reinstallation of dependencies.
3. Repeated dependencies between different closures need reinstallation, even when using pip cache, the installation speed remains slow.
