Error during the setup - version of Python

[djulien19]

During the setup of Odoo, I get this error message about the version of Python with the Docker image.
About the pip version on my mac:
pip 21.0.1 from /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/pip (python 3.7)
Thanks for the tip.

Step 5/5 : RUN pip install -r /tmp/requirements.txt

DEPRECATION: Python 3.5 reached the end of its life on September 13th, 2020. Please upgrade your Python as Python 3.5 is no longer maintained. pip 21.0 will drop support for Python 3.5 in January 2021. pip 21.0 will remove support for this functionality.
