python unicode error -> FileNotFoundError: The path does not exist.

[dyc081818]

I use pyinstaller to compile the Python project, and finally generate an exe executable file. When the exe file path contains unicode characters, it will report an error:

Traceback (most recent call last):
File "mediapipe_facemesh.py", line 81, in
File "mediapipe_facemesh.py", line 29, in show_face_mesh
File "mediapipe\python\solutions\face_mesh.py", line 94, in init
File "mediapipe\python\solution_base.py", line 237, in init
FileNotFoundError: The path does not exist.

Hi @dyc081818, Could you please provide the steps to reproduce the above error. Thanks!

I wrote a simple example script in python, like the following, it can run successfully

import sys
sys.path.append("E:/mediapipe/mp_env/Lib/site-packages")

import cv2
import mediapipe as mp

def show_face_mesh(cap_id):
    mp_drawing = mp.solutions.drawing_utils
    mp_face_mesh = mp.solutions.face_mesh
    
    cap = cv2.VideoCapture(cap_id, cv2.CAP_DSHOW)
    with mp_face_mesh.FaceMesh (
        static_image_mode=False,
        max_num_faces=1,
        min_detection_confidence=0.1,
        min_tracking_confidence=0.1) as face_mesh:

        while cap.isOpened():
            success, frame = cap.read()
            if not success: 
                print("ignore empty camera frame")
                continue
            
            frame.flags.writeable = False
            frame = cv2.cvtColor(frame, cv2.COLOR_BGR2RGB)
            results = face_mesh.process(frame)

            # Draw the face mesh annotations on the image.
            frame.flags.writeable = True
            frame = cv2.cvtColor(frame, cv2.COLOR_RGB2BGR)

            if results.multi_face_landmarks is not None:
                for face_landmarks in results.multi_face_landmarks:
                    mp_drawing.draw_landmarks(
                        frame, face_landmarks, mp_face_mesh.FACEMESH_CONTOURS
                    )

            cv2.imshow('Frame', cv2.flip(frame, 1))
            if cv2.waitKey(1) & 0xFF == 27:
                break

    cap.release()
    cv2.destroyAllWindows()

if __name__ == '__main__':
    show_face_mesh(0)

But if you add Unicode characters to the path of pip site-packages, for example, like this:

import sys
sys.path.append("E:/mediapipe/mp_env/Lib/site-packages中文")

This error will appear: "FileNotFoundError: The path does not exist." It is no problem to remove the Unicode characters.

I tried to find the C++ code. The error was reported in the mediapipe/framework/deps/file_helpers.cc file. In Exists function failed to use stat to check whether the file exists.

Then I create a new C++ project and try to call the stat function. It is no problem to add Unicode characters to the path. It is not too clear why the stat function called by mediapipe fails.

Similar to #2162 (comment)?

No, the title was wrong and I corrected it immediately.

I found this problem after packaging with pyinstaller, but then I tested it in the editor and the same error, indicating that it was not a problem with pyinstaller

Has anyone encountered this problem?

This helped me with the 237 line error, I just followed the instruction of [Bar-Levav] (edited .spec file + special pyinstaller compilation command):

Thanks Reply
But obviously that approach is too cumbersome, I can offer an easier way in spec file:
a = Analysis(py_files, pathex=[], binaries=[], datas=[('Python Path/Lib/site-packages/mediapipe/modules', 'mediapipe/modules')],

The above configuration is added to copy the modules folder to the target folder, and it can run correctly
But if the path of the exe contains unicode characters, it will report an error

File "mediapipe\python\solutions\face_mesh.py", line 94, in init
File "mediapipe\python\solution_base.py", line 237, in init
FileNotFoundError: The path does not exist.

mediapipe doesn't seem to be able to find binaries in paths containing unicode

Hello, I'm having this same problem using midiapipe, can you help me.

Hello @dyc081818,
We are upgrading the MediaPipe Legacy Solutions to new MediaPipe solutions However, the libraries, documentation, and source code for all the MediaPipe Legacy Solutions will continue to be available in our GitHub repository and through library distribution services, such as Maven and NPM.

You can continue to use those legacy solutions in your applications if you choose. Though, we would request you to check new MediaPipe solutions which can help you more easily build and customize ML solutions for your applications. These new solutions will provide a superset of capabilities available in the legacy solutions.
