python - 无法使用pytesseract从图像中获取文本

Question

当我使用下面的代码时，得到的错误是“WindowsError:[Error 2] The system cannot find the file specified”。请帮我从图片中获取文字。

from pytesseract import image_to_string
from PIL import Image

print image_to_string(Image.open(r'D:\\name.jpg'),lang='eng')

错误:

WindowsError Traceback (most recent call last) in () 2 from PIL import Image 3 ----> 4 print image_to_string(Image.open(r'D:\name.jpg'),lang='eng')

从 tesseract-ocr 安装 google tesseract-ocr .代码可能会遗漏依赖项。
