在学opencv时遇到了“拒绝访问”，尝试了一些办法，还是没有解决

在学opencv的时候，跟着up主做一个文档识别的小项目，但是在pytesseract这一块代码运行的时候，报错显示PermissionError拒绝访问。

代码如下：

import cv2
import pytesseract
import os
from PIL import Image

preprocess = 'blur'

image = cv2.imread('scan.jpg')
gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)

if preprocess == "thresh":
    gray = cv2.threshold(gray, 0, 255, cv2.THRESH_BINARY | cv2.THRESH_OTSU)[1]

if preprocess == "blur":
    gray = cv2.medianBlur(gray, 3)

filename = "{}.png".format(os.getpid())
cv2.imwrite(filename, gray)

text = pytesseract.image_to_string(Image.open(filename))
print(text)
os.remove(filename)

cv2.imshow("Image", image)
cv2.imshow("Output", gray)
cv2.waitKey(0)

运行结果及报错内容如下：

    hp, ht, pid, tid = _winapi.CreateProcess(executable, args,
PermissionError: [WinError 5] 拒绝访问。

因为从来没有遇见过这种问题，在网上搜索了几种办法（环境变量已经添加，也已经把pytesseract.py中的路径改为了绝对路径），所在文件夹的权限也是完全控制，可是问题还没有解决，所以来求助，感谢。

用管理员权限运行代码试试
