Не получается нормально установить pytesseract ( Py 2.7 or 3.4) . Установил PIL , python-tesseract and tesseract-ocr. Например при вызове print pytesseract.image_to_string(Image.open('C:\Python27\lib\site-packages\PIL\test.png')) выдает: IOError: invalid mode ('rb') or filename: ‘C:\\Python27\\lib\\site-packages\\PIL\test.png’ .

\t в пути воспринимается как табуляция. Поставь r перед кавычками.

В этом случае:

>>> print pytesseract.image_to_string(Image.open(r'C:\Python27\lib\site-packages\PIL\test.png'))

Traceback (most recent call last):

Help on function image_to_string in module pytesseract.pytesseract:
image_to_string(image, lang=None, boxes=False, config=None)
    Runs tesseract on the specified image. First, the image is written to disk,
    and then the tesseract command is run on the image. Resseract's result is
    read, and the temporary files are erased.    
    also supports boxes and config.    
    if boxes=True
        "batch.nochop makebox" gets added to the tesseract call
    if config is set, the config gets appended to the command.
        ex: config="-psm 6"
