 **[Tesseract](https://github.com/tesseract-ocr/tesseract)** was originally written in C++ and uses an LSTM Network behind the scenes, for more reading and installation guide, you can check out this very helpful [blog post](https://appliedmachinelearning.blog/2018/06/30/performing-ocr-by-running-parallel-instances-of-tesseract-4-0-python/). This will explain you the essential stuff. I have also extended this for PDFs to make it more useful for real-world use-case.
