To generate simple ocr executable app by pyinstaller with tesseract.
Tesseract library needs to be installed locally
Language models can be downloaded from tesseract-ocr. Place tessdata model inside tesseract_files/tessdata when you change model to build by pyinstaller.
pyinstaller --onefile --add-data "tesseract_files/tesseract:./tesseract_files" --add-data "tesseract_files/tessdata:./tesseract_files/tessdata" python_ocr/main.py --name python_ocr_fast
./dist/python_ocr_fast input/ocr_example_1.png
Results should be like this below
