Issue
I am trying to use the following OCR project that is found here on github. I am using python 3 virtual environment. I am on Windows. I installed successfully requirements.txt using Python 3.6.7, however when I am attempting to do python install setup.py I get the following error:
AssertionError: you must install and use OCRopus with Python version 2.7 or later, but not Python 3.x
Having this said, I reverted back and tried to use Python 2.7 with the virtual environment using pyenv-win link. When I try to install requirements.txt with the virtual env of python 2.7 I get the following error:
DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. pip 21.0 will drop support for Python 2.7 in January 2021. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support

Does that mean I cannot install these python packages at all using python 2.7 ? I have to use this repository for my project.
Solution
For anyone who stumbles upon this in the future, ocropy needs Python 2.7 but numpy and scipy newest versions dropped Python 2.7 support. However, you can still use them but the problem is that our developer folks will stop supporting bug fixes.
My problem was mainly the global version of Python I have on my system (windows) is 3.6.7 while ocropus requires 2.7. I downloaded a broken executable for Python 2.7 that did not have the Scripts folder installed, thus pip ended up not working at all.
Followed this tutorial that shows how to install another version of python (2.7) and the problem was solved when I downloaded the following executable
In order to use thevirtualenv properly with python 2.7 use the following command
# dont forget to add python.exe
virtualenv -p C:\Python27\python.exe venv/ocropus
Goodluck.
