ERROR: Package 'object-detection' requires a different Python: 2.7.12 not in '>3.6'

Question

I am trying to install tensorflow-object-detection API. Installed Tensorflow-gpu-2.1.0 already with pip.

sudo python -m pip install --use-feature=2020-resolver tensorflow-gpu

But when trying to install tensorflow-object-detection-api I am getting this error : ERROR: Package 'object-detection' requires a different Python: 2.7.12 not in '>3.6'

Same with python3 : ERROR: Package 'object-detection' requires a different Python: 3.5.2 not in '>3.6'

The error is shown when running the following command in the installation step :

python -m pip install --use-feature=2020-resolver .

O.S : Ubuntu 16.04

Python: 2.7.12

Answer 1

The error is pretty plain.

You're attempting to use a package which requires Python 3.6 with Python 2.7 (which is end-of-life since January 2020), and then with Python 3.5 (which is end-of-life tomorrow, at the end of September 2020).

Upgrade your system to a newer Python; 3.8 is the current version.
