For PyTesseract, the command is like below

pip install tesserocr-2.4.0-cp36-cp36m-win_amd64.whl

The error is below

WARNING: Requirement 'tesserocr-2.4.0-cp36-cp36m-win_amd64.whl' looks like a filename, but the file does not exist
ERROR: tesserocr-2.4.0-cp36-cp36m-win_amd64.whl is not a supported wheel on this platform.

Anyone has any idea on how can I download OCR that works well with Python?

Answer 1

Your Python version is 3.7

But you are trying to install tesserocr-2.4.0-cp36-cp36m-win_amd64.whl(which is applicable to python version 3.6)

Try to install tesserocr specific to installed Python version (python 3.7) 'tesserocr-2.4.0-cp37-cp37m-win_amd64.whl'

Check for your OS supported versions https://github.com/simonflueckiger/tesserocr-windows_build/releases
