tesseract安裝說明

INSTALLATION:

Prerequisites:

• Python-tesseract requires python 2.5 or later or python 3.
• You will need the Python Imaging Library (PIL). Under Debian/Ubuntu, this is
  the package "python-imaging" or "python3-imaging" for python3.
• Install google tesseract-ocr from http://code.google.com/p/tesseract-ocr/ .
  You must be able to invoke the tesseract command as "tesseract". If this
  isn't the case, for example because tesseract isn't in your PATH, you will
  have to change the "tesseract_cmd" variable at the top of 'tesseract.py'.
  Under Debian/Ubuntu you can use the package "tesseract-ocr".

Installing via pip:
See the pytesseract package page
