Error occurs on loading the cascade file Nose18X15.xml

I am trying to build timlapses off of the code used to capture and compile a timelapse. I wave deleted the code for capturing images as I simply want to use images take with my personal camera. I have also done my best (I'm very new to this) to remove references to other code files like the utils.py file. I wanted this to be a simple and stand alone code for my sake. As far as I can tell, it works. it pulls all the files I want and creates a video, the problem is that the video is extremely choppy and isn't much better running at lower resolution. this is what I've got.

`import os
import numpy as np
import cv2
import time
import datetime

import glob

#Vairables
frames_per_second = 24
save_path='saved-media/timelapse.mp4'

out = cv2.VideoWriter(save_path, cv2.VideoWriter_fourcc(*'mp4v'), frames_per_second, (1620, 1080))
timelapse_img_dir = r'E:\Nature\Sky captures\2021-10-19_Timelapse_PythonFJPG'

clear_images = False

def images_to_video(out, timelapse_image_dir, clear_images=False):
image_list = glob.glob(f"{timelapse_image_dir}/*.JPG")
sorted_images = sorted(image_list, key=os.path.getmtime)

for file in sorted_images:
    ImageToVideoFrames = cv2.imread(file)
    out.write(ImageToVideoFrames)
return (0)

images_to_video(out, timelapse_img_dir)
out.release()
cv2.destroyAllWindows()
print ('complete')`

Hello @codingforentrepreneurs ,
I am using the same code as of yours and when I run it it shows me the following

Here is the code
`import cv2
import os
import numpy as np
from PIL import Image
import pickle

BASE_DIR = os.path.dirname(os.path.abspath(file))
image_dir = os.path.join(BASE_DIR, "images")

face_cascade = cv2.CascadeClassifier('cascades/data/haarcascade_frontalface_alt2.xml')
recognizer = cv2.face.LBPHFaceRecognizer_create()

current_id = 0
label_ids = {}
y_labels =[]
x_train = []

for root, dirs, files in os.walk(image_dir):
for file in files:
if file.endswith(".png") or file.endswith(".jpg"):
path = os.path.join(root, file)
label = os.path.basename(os.path.dirname(path)).replace(" ", "-"). lower()
#print(label, path)
if not label in label_ids:
label_ids[label] = current_id
current_id +=1
id_ = label_ids[label]

		pil_image = Image.open(path).convert("L")
		image_array = np.array(pil_image, "uint8")
		#print(image_array)
		faces = face_cascade.detectMultiScale(image_array, scaleFactor=1.5, minNeighbors=5)
		for (x,y,w,h) in faces:
			roi = image_array[y:y+h, x:x+w]
			x_train.append(roi)
			y_labels.append(id)

with open("labels.pickle", 'wb') as f:
pickle.dump(label_ids, f)

recognizer.train(x_train, np.array(y_labels))
recognizer.save("trainner.yml")`

I am getting error

i have a problem 😂🤣

labels = {"person_name": 1} with open("labels.pickle", 'rb') as f: og_labels = pickle.load(f) labels = {v:k for k,v in og_labels.items()}

Traceback (most recent call last):

og_labels = pickle.load(f)

how to fix it ? help me please 😂😂👨‍💻

Hi guys
I just got all the code and thought i got all the way though the FR stuff but i keep getting a error when i run faces.py

PS C:\Users\ADBY\Desktop\Coding\OpenCV-Python-Series-master\src> python .\faces.py
OpenCV Error: Unspecified error (File can't be opened for reading!) in cv::face::FaceRecognizer::read, file C:\projects\opencv-python\opencv_contrib\modules\face\src\facerec.cpp, line 61

cv2.error: C:\projects\opencv-python\opencv_contrib\modules\face\src\facerec.cpp:61: error: (-2) File can't be opened for reading! in function cv::face::FaceRecognizer::read

can any one tell me what to do? i am receiving this error. How to resolve it?

recognizer.read('trainer/trainer.yml')
cv2.error: OpenCV(4.1.0) C:\projects\opencv-python\opencv_contrib\modules\face\src\facerec.cpp:61: error: (-2:Unspecified error) File can't be opened for reading! in function 'cv::face::FaceRecognizer::read'

Thanks in advance.

Hey guys.
I'm here with this bug in my code and I can't even find a solution for it.
I've already used "load" instead of "read", but still an error appears. When I change the opencv version, I can't create the training "yml" file anymore.
Below is my code with the "yml" file already created.

from PIL import Image
import cv2
import numpy as np
import os

lbph_face_classifier = cv2.face.LBPHFaceRecognizer_create()
lbph_face_classifier.read('/train/lbph_classifier.yml')
imagem_teste = ('C:/Users/MD Francisco/Desktop/Expert/dlib/Reconhecimento/yalefaces/test/subject10.sad.gif')
imagem = Image.open(imagem_teste).convert('L')
imagem_np = np.array('uint8')
print(imagem_np)

Its showing me an error like this

Hi,

i retrained the model simply by putting my face images there into images folder with the folder named by name and run the training steps.

But even after changing the model named to the new created model i am setting getting old labels...
in other words, my name is not coming with my face, i think training wasn't successful.

Any solution?
thanks

Hi everyone,
I would love to contribute to this project, however I am not sure if maintainers are still active here ... 🤔
Would appreciate your answer.

How can I fix it?

I was trying to run the code but it resulted in this error.
File "c:/Users/SCT/Desktop/Siddhartha/classified project details/realtime_recog.py", line 35 font = cv2.FONT_HERSHEY_SIMPLEX ^ TabError: inconsistent use of tabs and spaces in indentation

there is no download button showing how can I download this repository?
