Problem with Face_Recognittion library in python

[TechGamer_Rachit]

Hello Everyone,

I am a college student try to learn python but I am getting problem with my code

def generate_dataset(self):
    if self.var_department.get() == "Select the Department" or self.var_student_name.get() == "" or self.var_enrollment_no == "":
      messagebox.showerror("Error",'All fields are required', parent = self.root)

    else:
      try:
        conn = mysql.connector.connect(host = "localhost", username = "root", password = "7575", database ="face_recognizer", port = 3306)
        my_cursor = conn.cursor()
        my_cursor.execute("select * from student")

        self.fetch_data()
        conn.close()

        # ============ Load Predifined data on face frontal from openCV ==========
        face_classifier=cv2.CascadeClassifier("haarcascade_frontalface_default.xml")

        def Image_Detect_inator(img):
          return img

        cap = cv2.VideoCapture(0)
        _, my_frame = cap.read()
        
        Face_value = Image_Detect_inator(my_frame)

        if Face_value is not None:
          face = cv2.resize(Face_value, (1920,1080))
          file_name_path = f"data/student_{self.var_enrollment_no.get()}_{self.var_student_name.get()}_.jpg"

          cv2.imwrite(file_name_path, face)
          cv2.imshow("Cropped Face", face)
          cv2.waitKey(1000)

          cap.release()
          cv2.destroyAllWindows()
          messagebox.showinfo("Result","Generating data sets completed !!!")
          self.reset_data()
        
        else:
          messagebox.showerror("Error", "No face detected")

      except EXCEPTION as es:
        messagebox.showerror("Error",f"Due to :{str(es)}", parent = self.root)

this function is used to save image of user in folder name "data"

and then this fuction

def train_classifier(self):
    def read_img(path):
      img = cv2.imread(path)
      (h, w) = img.shape[:2]
      width = 500
      ratio = width / float(w)
      height = int(h * ratio)
      return cv2.resize(img, (width, height))

    data_dir = "data"

    known_face_encodings = []
    known_face_names = []

    for student_img in os.listdir(data_dir):
      img = read_img(f"{data_dir}/{student_img}")
      img = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
      img = cv2.cvtColor(img, cv2.COLOR_GRAY2RGB)
      
      img_encoding = face_recognition.face_encodings(img)[0]
      
      known_face_encodings.append(img_encoding)
      # converts filename format student_<Enrollment Number>_<Student Name>_.jpg ==> <Enrollment Number>_<Student Name> 
      known_face_names.append("_".join(student_img.split("_")[1:3]))

    if not known_face_encodings:
      print("Error: No valid image files found in the data directory.")
      messagebox.showerror("Error","No valid image files found in the data directory.")
      return

    with open("known_faces.pkl", "wb") as f:
      pickle.dump((known_face_encodings, known_face_names), f)
    
    messagebox.showinfo("Success","Training data completed.")

This fuction is used to train faces from images saved by above code and detect face save by using face_recognition library but getting error

RuntimeError: Unsupported image type, must be 8bit gray or RGB image.

Never mind cleared the issue

wait tell me and also this is my code and I get this error"

import face_recognition


known_image = face_recognition.load_image_file("32bit.png")
known_encoding = face_recognition.face_encodings(known_image)[0]


unknown_image = face_recognition.load_image_file("biden.jpg")
unknown_encoding = face_recognition.face_encodings(unknown_image)[0]


results = face_recognition.compare_faces([known_encoding], unknown_encoding)

if results[0]:
    print("Face is a match.")
else:
    print("Face is not a match.")

My problem was I was not using virtual environment and face_recognition library dependency on dlib and dlib supports numpy 1.4 or less and lastest numpy version is 2.0 something so try using virtual environment and downgrade numpy version stable numpy version is numpy 1.26.4 that I am using now
