FileNotFoundError: The path does not exist , while using mediapipe for hand detection

Question

我正在尝试使用 mediapipe 在网络摄像头源上完成手部检测，但是当我运行代码时，我收到以下错误：

**File "D:\HandTracking\handtracking.py", line 9, in <module>
    hands = mpHands.Hands()**

  **File "C:\Users\Θανάσης\AppData\Local\Programs\Python\Python39\lib\site-packages\mediapipe\python\solutions\hands.py", line 109, in __init__
    super().__init__(**

  **File "C:\Users\Θανάσης\AppData\Local\Programs\Python\Python39\lib\site-packages\mediapipe\python\solution_base.py", line 237, in __init__
    validated_graph.initialize(
FileNotFoundError: The path does not exist.**

**[ WARN:0] global C:\Users\runneradmin\AppData\Local\Temp\pip-req-build-1i5nllza\opencv\modules\videoio\src\cap_msmf.cpp (438) `anonymous-namespace'::SourceReaderCB::~SourceReaderCB terminating async callback**

代码为：

import cv2 as cv
import mediapipe as mp

capture = cv.VideoCapture(0)
mpHands = mp.solutions.hands
hands = mpHands.Hands()

while True:
    isTrue, frame = capture.read()
    frameRGB = cv.cvtColor(frame, cv.COLOR_BGR2RGB)
    results = hands.process(frameRGB)
    cv.imshow("Frame", frame)

    if cv.waitKey(20) & 0xFF == ord('d'):
        break

capture.release()
cv.destroyAllWindows()

Answer 1

我使用 here 解决了这个问题。我认为问题是路径名上的路径编码。

所以主要思路是将用户文件夹名称改成英文

Microsoft提供了更改用户文件夹的方法供大家参考。

Log in by using another administrative account.

Note : You may need create a new administrative account at first.

Go to the C:\users\ folder and rename the sub folder with the original user name to the new user name.

Go to registry and modify the registry value ProfileImagePath to the new path name. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList<User SID>\

Note : Replace with the new name you want to change to your user account.

Log out and log in again by using the user whose name is changed, and the user should use the previous profile with new path name.

Answer 2

当项目路径中存在非unicode字符时，会出现此错误。它不仅与用户名有关，而且与路径名中包含的所有字符有关。例如，如果项目的路径名中包含“ç”、“ş”、“ü”、“ğ”、“ı”、“ö”等字符，则会出现此错误。

为了消除此错误，请在没有“非 unicode”字符的文件夹中构建项目。

它真的对我有用...
