No OCR tool found

[Williamvdb]

I have tesseract installed. I have used it many times before, but when I use this script:

from PIL import Image
import sys

import pyocr
import pyocr.builders

tools = pyocr.get_available_tools()
if len(tools) == 0:
    print("No OCR tool found")
    sys.exit(1)
tool = tools[0]
print("Will use tool '%s'" % (tool.get_name()))

langs = tool.get_available_languages()
print("Available languages: %s" % ", ".join(langs))
lang = langs[0]
print("Will use lang '%s'" % (lang))

txt = tool.image_to_string(Image.open('test.png'),
                           lang=lang,
                           builder=pyocr.builders.TextBuilder())
word_boxes = tool.image_to_string(Image.open('test.png'),
                                  lang=lang,
                                  builder=pyocr.builders.WordBoxBuilder())
line_and_word_boxes = tool.image_to_string(
        Image.open('test.png'), lang=lang,
        builder=pyocr.builders.LineBoxBuilder())

It says there is no OCR tool found. Any fix?

I need more information:

• Which OS / GNU/Linux distribution do you use ?
• Is tesseract in your PATH ?

@jflesch I use mac. is this not supposed to work on a mac?

If it is, though, how do I put tesseract in my path?

It has been tested only on GNU/Linux systems. It should also work on similar systems (*BSD, etc). It doesn't work on Windows, MacOSX, etc.

I have no Mac. I can't test it on Mac, so I can't support it. Sorry.

@jflesch I use it on Win10, and I also get ''No OCR Tool Found''. Doesn't it support windows?

[jflesch]

It does support Windows (see https://openpaper.work/download ). However, Tesseract.exe must be in your PATH.

hi @jflesch i can't found any exe in your package. Can you help me on this

[jflesch]

There are no .exe in Pyocr. Pyocr is a Python module designed to make it easier to use OCR tools from Python.

Pyocr looks for the OCR tools (Tesseract, Cuneiform, etc) installed on your system and just tells you what it has found.

You have to install Tesseract by yourself.

Thanks for your response
