这是我的问题,我想使用pytesser来获取图片的内容。我的操作系统是Mac OS 10.11,已经安装了PIL,pytesser,tesseract-ocr引擎以及其他支持的库,例如libpng等。但是当我运行我的代码时,如下所示,会发生错误。
from pytesser import *
import os
image = Image.open('/Users/Grant/Desktop/1.png')
text = image_to_string(image)
print text
接下来是错误信息
Traceback (most recent call last):
File "/Users/Grant/Documents/workspace/image_test/image_test.py", line 10, in <module>
text = image_to_string(im)
File "/Users/Grant/Documents/workspace/image_test/pytesser/pytesser.py", line 30, in image_to_string
call_tesseract(scratch_image_name, scratch_text_name_root)

File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/subprocess.py", line 1335, in _execute_child
raise child_exception
OSError: [Errno 2] No such file or directory
此外,tesseract-ocr引擎在我的Mac上运行良好,我可以在终端中运行它并获得结果。下面是测试图片结果。
tesseract result
有人可以帮我解决这个问题吗?
最佳答案
幸运的是,我解决了这个问题。
首先,我运行命令
pip install pytesseract
安装软件包。
但是我收到“没有使用pytesser的此类文件或目录”的错误消息。
然后,我阅读了此链接:image_to_string doesn't work in Mac
因此,只需运行以下脚本:
brew link libtiff
brew link libpng
brew link jpeg
brew install tesseract
为我工作〜
