Describe the bug

Description

A customer reported that the Python Client SDK currently requires a Python version higher than 3.8.
This prevents them from using the SDK in their environment.

Background / Reason

• Ubuntu 20.04 (default Python 3.8) is commonly used on their devices.
• Some RK embedded devices used by the customer also run Ubuntu 20.04 with Python 3.8.
• Upgrading Python on these systems may not be feasible, so SDK compatibility with Python 3.8 is necessary.

Steps to reproduce

1. Install the SDK in a Python 3.8 environment (e.g., Ubuntu 20.04 or RK embedded device).
2. Attempt to import or use the client package.
3. Observe installation or compatibility errors.

Expected behavior

The Python Client SDK should support Python 3.8 to allow usage on these customer systems.

Environment

• Python version: 3.8
• SDK version:
