Python PyCharm image_to_string 报错解决方法

Traceback (most recent call last):
  File "D:/PycharmProjects/net.bjxueche/CoreImage.py", line 82, in 
    text = image_to_string(image=image, boxes=True)

FileNotFoundError: [WinError 2] 系统找不到指定的文件。   

报上述错误按如下步骤处理：

1. 将pytesseract.py中如下代码改了：

#tesseract_cmd = 'tesseract' #raw, modify 2018/02/11 
tesseract_cmd = 'D:/python/python-3.6.4-embed-amd64/tesseract-ocr/tesseract.exe' #my real exe file path

tesseract.exe 下载地址：http://download.csdn.net/download/kaiyoushiwo007/10250213

2. tessdata拷贝到exe的所在目录. tessdata 是字符库，下载链接：http://download.csdn.net/download/kaiyoushiwo007/10250213

如果只做第一步不做第二步会报这个错误：

Error opening data file ./tessdata/eng.traineddata
Please make sure the TESSDATA_PREFIX environment variable is set to the parent directory of your "tessdata" directory.
Failed loading language 'eng'
Tesseract couldn't load any languages!
Could not initialize tesseract.

好了，这个问题解决了。如果遇到问题可以留言，一起研究。
