You are using pip version 18.1, however version 20.0.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

Official “Install” page says, that you are required to have pip>=19 to install tensorflow:

System requirements
pip 19.0 or later (requires manylinux2010 support)

But you have pip18.1. I’d try running pip install --upgrade pip as the error message recommends before you install this package.

On Tensorflow’s install page they require a Python version that is >= 3.5, ❤️.8 which is why 3.6 worked but 3.8 didn’t.

The page also specifies that one needs pip 19.0 or later.

TLDR to correctly install Tensorflow with poetry:

• Use a Python version that is from 3.5 to 3.7
• Use pip version 19.0 or later
