Fix:
Force the environment to use Python 3.9, which is the latest compatible version.

1. Using Docker (Recommended)

dockerfile

FROM python:3.9.22-slim  # Explicitly use Python 3.9
RUN pip install absl-py==0.9.0

2. Locally (Without Docker)

bash

python3.9 -m pip install absl-py==0.9.0

Why Python 3.9?

• absl-py==0.9.0 was tested on Python 3.4–3.9.

• Python 3.10+ introduces breaking changes that block installation.

No Workarounds Needed → Just use Python 3.9 and it will work.
