Python：为Windows 7安装Tesseract

Question

My objective is to use OCR in Python 2.7 using Tesseract on a Windows 7 machine, but I am running into issues as for the installation process. I tried following the instruction here but the link to "tesseract-core-yyyymmdd.exe" and "tesseract-langs-yyyymmdd.exe" do not exist anymore and I can't find these .exe elsewhere online. Here's what I have done so far:

1. installed tesseract from its executable from official tesseract-ocr page.
2. installed via pip packages "wand", "PIL", "pyocr".

Now, if I do the following in Python:

from wand.image import Image from PIL import Image as PI import pyocr import pyocr.builders import io

No problem loading up these packages but pyocr.get_available_tools() gives me an empty list. I am sure this has to do with the missing installation .exe files above. Where can I find them? Is it something else that I am missing?

Answer 1

I just tried to set up pytesseract and it works ! I have windows 10 and python 2.7 installed.

all you need to do :

1. Download Visual basic C++ from http://aka.ms/vcpython27 and install it (common installation step)

2. Download tesseract from python via this link https://pypi.python.org/pypi/pytesseract

3. Unizip the file.

4. Go to the directory which contains the unizip file

5. Run this command " python setup.py install "

6. (Additional) to test if it's installed, go to your python shell and run this command " import pytesseract "

I hope it works !! Note pytesseract is google based OCR, it works similarly to tesseract.

PIP is a package manager for Python packages

1. Open cmd run pip search "pytesseract" , you can see latest version
2. Run pip install pytesseract for latest version or pip install pytesseract==0.3.0 for version you want.
3. In windows python cmd run import pytesseract for sure installed was successful.
