pytesseract PermissionError：[WinError 5] CreateProcess 中的访问被拒绝（Windows 10）

Question

尝试制作一个 OCR 程序，可以从图像中提取文本，将其转换为字节，然后让 pytesseract 将其转换为字符串。 我遇到了一些权限错误。 这是我现在的代码。 我不能 MRE 这段代码，所有这些都很重要。

import cv2
import pytesseract
import numpy as np

# Set the path to the tesseract executable
pytesseract.pytesseract.tesseract_cmd = "C:\\Users\\hypro\\AppData\\Local\\Programs\\Tesseract-OCR"

img = cv2.imread('C:\\Users\hypro\Downloads\image1.jpg')
#Alternatively: can be skipped if you have a Blackwhite image
gray = cv2.cvtColor(img, cv2.COLOR_RGB2GRAY)
gray, img_bin = cv2.threshold(gray,128,255,cv2.THRESH_BINARY | cv2.THRESH_OTSU)
gray = cv2.bitwise_not(img_bin)
kernel = np.ones((2, 1), np.uint8)
img = cv2.erode(gray, kernel, iterations=1)
img = cv2.dilate(img, kernel, iterations=1)
# Encode the image as a JPEG
_, encoded_image = cv2.imencode('.jpg', img)
print(encoded_image)
# Convert the encoded image to a string
image_bytes = encoded_image.tobytes()
out_below = pytesseract.image_to_string(img)
print("OUTPUT:", out_below)

我试着检查目录是否正确：是的。 我有权执行 tesseract.exe，并有权查看它。 这是我的完整回溯：

你能确认你有正确的 tesseract 可执行文件路径吗？

根据pytesseract docs ，可执行路径应该类似于C:\Program Files (x86)\Tesseract-OCR\tesseract

在你的情况下，你可能需要做

pytesseract.pytesseract.tesseract_cmd = "C:\\Users\\hypro\\AppData\\Local\\Programs\\Tesseract-OCR\\tesseract"
