Question

我有这个代码：

try:   
    from PIL import Image as Img
    import os
    import pytesseract as tss
except ImportError as error:
    raise Exception(str(e))

from passporteye import read_mrz
#So far you're using windows always do this; esp. if you've haven't add teseract.exe to PATH
#tesseract_cmd=r'C:\Program Files (x86)\Tesseract-OCR'

def Get_mrz(image_file):
    print("This will take a while.")
    try:
        mrz=read_mrz(image_file,save_roi=True)
        print("Done")
    except Exception as e:
        raise Exception("THERE WAS AN EXCEPTION "+str(e))
    
    if mrz!=None:
        print(mrz)
    else:
        return "Cannot read text"
def Credits():
    print("This is work...")

#The test is below
Get_mrz("img/id_card2f.jpg")
Credits()

一直报这个错误：

Traceback (most recent call last):
  File "main_stuff.py", line 28, in <module>
    Get_mrz("img/id_card2f.jpg")
  File "main_stuff.py", line 18, in Get_mrz
    raise Exception("THERE WAS AN EXCEPTION "+str(e))
Exception: THERE WAS AN EXCEPTION tesseract is not installed or it's not in your PATH. See README file for more information.

但我不知道为什么。Tesseract-ocr 二进制文件已成功安装并添加到我的 PATH 中。 我知道这一点，因为如果我在它给出的任何目录中运行 tesseract --version

像这样显式传递路径

tss.pytesseract.tesseract_cmd = r'<full_path_to_your_tesseract_executable>'
