tesserocr: OSX: RuntimeError: Failed to init API, possibly an invalid tessdata path

on OSX, I’m getting error when using other language. Here are all info I can get. Do you have any idea why this fails?

I met the same issue. And I found run at Eclipse environment will be OK. What’s different between run @Eclipse and run @Terminal ?

test 1: lang = ‘eng’ is OK but, lang = ‘chi_sim’ will meet this issue, and still OK @Eclipse environment. How ?

test 2: rename eng.traineddata to chi_sim.traineddata , then , test it again It’s OK so, this maybe caused by the download chi_sim.traineddata ? how to fix it?

finally, I got the solution for python:

add below code on your python code.

import locale locale.setlocale(locale.LC_ALL, “C”)

And, if you have two or more version of tesseract you do need set ‘TESSDATA_PREFIX’ to the proper one.

thank you, I’ve solved this problem by a hard way Switch to the folder to：C:\Program Files\Python36\Lib\site-packages\tesserocr `import tesserocr import os from PIL import Image

os.chdir(r"C:\Program Files\Python36\Lib\site-packages\tesserocr") image = Image.open(‘image.png’) print(tesserocr.image_to_text(image)) `

But,something tough are： Every time you have to switch the directory to tesserocr.
