This article introduces the knowledge of "how to use the pytesseract library of python". Many people will encounter such a dilemma in the operation of actual cases, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Description

1. Pytesseract needs to be used with the local tesseract-ocr.exe file.

2. It should be noted that the Chinese package must be selected during installation, and only English identification is supported by default.

Install the command pip install pytesseract instance import pytesseractfrom PIL import Imagetext = pytesseract.image_to_string (Image.open (r "d:Desktop39DEE621-40EA-4ad1-90CC-79EB51D39347.png")) print (text)

Prepare for

First install the Tesseract client on the machine, and then install the pytesseract library:

Pip install pytesseract

Install PIL if you haven't installed it, because the first parameter called is returned by the Image class:

Pip install PILLOW

Example

Import pytesseractfrom PIL import Imageimg = Image.open ("D://aa.jpg") text = pytesseract.image_to_string (img,) print (text) "how to use python's pytesseract Library" ends here.
