Docker build fails due to symlink conflict and deprecated setup.py install

[M4cr0Chen]

Hi team, when I'm running the docker build command the docker build fails with the following two issues:

1. ln -s /usr/bin/pip3 /usr/bin/pip fails. This is because pip3 install --upgrade pip (line 13) already creates /usr/bin/pip, so the subsequent ln -s errors with "File exists".

Suggested Fix: use ln -sf to force overwrite.

2. python setup.py install fails to install pandas. Since the setup.py install uses easy_install, which pulls pandas 3.0.1. That version requires Python 3.9+ and uses pyproject.toml, so easy_install can't find a setup script.

Suggested Fix: replace python setup.py install with pip install ., which correctly resolves pandas to a Python 3.8-compatible version.
