Tesseract的路径错误

Question

我以为我会让Tesseract在我的Win 7机器上工作：

from PIL import Image
import pytesseract

pytesseract.pytesseract.tesseract_cmd = 'C:\\Program Files (x86)\\Tesseract-OCR\\tesseract.exe'

tessdata_dir_config = '--tessdata-dir "C:\\Program Files (x86)\\Tesseract-OCR\\tessdata"'

myFile = r"D:\temp\OCR\rightness_of_rendering.tif"

print(pytesseract.image_to_string(Image.open(myFile)))

tesseract.exe位于C：\ Program Files（x86）\ Tesseract-OCR \ tesseract.exe中

eng.traineddata位于C：\ Program Files（x86）\ Tesseract-OCR \ tessdata

我得到的错误是

D:\LearnPython>D:\LearnPython\ocr_test.py
Traceback (most recent call last):
  File "D:\LearnPython\ocr_test.py", line 14, in <module>
    print(pytesseract.image_to_string(Image.open(myFile)))
  File "C:\Python27\lib\site-packages\pytesseract\pytesseract.py", line 125, in
image_to_string
    raise TesseractError(status, errors)
pytesseract.pytesseract.TesseractError: (1, u'Error opening data file \\Program
Files (x86)\\Tesseract-OCR\\eng.traineddata')

D:\LearnPython>

这是一个目录，所以我有点困惑，如何设置它以便它将正常工作。

来自pytesseract github page

tessdata_dir_config = '--tessdata-dir "<replace_with_your_tessdata_dir_path>"'
# Example config: '--tessdata-dir "C:\\Program Files (x86)\\Tesseract-OCR\\tessdata"'
# It's important to add double quotes around the dir path.

pytesseract.image_to_string(image, lang='chi_sim', config=tessdata_dir_config)

请注意，您需要在config=tessdata_dir_config电话中提供image_to_string

因此，如果您使用的是英国数据，那就是

print(pytesseract.image_to_string(Image.open(myFile), lang='eng', config=tessdata_dir_config))
