Summary of Changes

Hello @derrickaw, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a significant refactoring of the tox.ini configuration within the Python SDK. The primary goal is to enhance the maintainability and clarity of dependency management for various transformers testing environments. By transitioning from direct dependency listings to using environment variables, the configuration becomes more modular and easier to update, ensuring consistent and streamlined test setups across different dependency sets.

Highlights

• Refactored Dependency Management: The tox.ini file has been updated to refactor how dependencies are declared and managed for the transformers test environments.
• Environment Variable Usage: Specific dependencies for different transformers versions (428, 447, 455, latest) are now defined within DEPS environment variables in the setenv section.
• Consolidated Common Dependencies: Common dependencies like tensorflow, protobuf, and pip have been grouped into a COMMON_DEPS environment variable for cleaner configuration.
• Updated Installation Command: The pip install command in the commands section now dynamically installs dependencies by referencing the newly defined DEPS and COMMON_DEPS environment variables.
