Question

我已经使用

安装了tasseract

pip install pytesseract

每当我试图运行这段代码时

from PIL import Image
import pytesseract
im = Image.open('hasan1.jpg')
print (pytesseract.image_to_string(im))

我收到了这些错误。

 Traceback (most recent call last):

 text = pytesseract.image_to_string(Image.open(filename))

我相信PyTesseract要求你在你的系统上安装tesseract库 - PyTesseract正在尝试运行命令行界面，但它无法找到它，大概是因为你只安装了python绑定。

如果您使用的是基于Ubuntu / Debian的系统，可以尝试：

sudo apt-get install tesseract-ocr

您可以查看Tesseract安装文档以获取更多信息：https://github.com/tesseract-ocr/tesseract/wiki

FileNotFoundError：[Errno 2]没有这样的文件或目录：'tesseract'
