Remember to:

  • Ask your Python question, not if you can ask or if there's an expert who can help.
  • Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
  • Explain what you expect to happen and what actually happens.

:warning: Do not pip install anything that isn't related to your question, especially if asked to over DMs.

Closes after a period of inactivity, or when you send !close.

import cv2

# Open a connection to the webcam (0 is the default camera)
cap = cv2.VideoCapture(0)

while True:
    # Capture frame-by-frame
    ret, frame = cap.read()
    
    if not ret:
        break
    
    # Display the frame
    cv2.imshow('Webcam', frame)
    
    # Break the loop on 'q' key press
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break

# Release the capture and close windows
cap.release()
cv2.destroyAllWindows()
#

try this its a base template for opening the webcam

#

show me the error your getting if it doesnt open

#

ooh its your camera

#

is it an external one ?

#

lemme take a look

#

maybe your mac isnt giving permissions to your python to be used

#

check your os settings

#

System Preferences > Security & Privacy > Privacy > Camera

#

it has nothing to do with the editor

it does not have to do with your efitor

# 
import cv2
import numpy as np
img = np.zeros((512, 512, 3), np.uint8)
cv2.rectangle(img, (100, 100), (300, 300), (0, 255, 0), 3)
cv2.imshow("rectangle", img)
cv2.waitKey(0)
cv2.destroyAllWindows()

#

no window at al?

#

can you run it without pressing anything right after it might be that you accidentally closed it

#

ok what python version are you using?

#

can you do python --version in terminal

#

ok

#

do in your terminal this
python <filename>.py

#

this is very strange

#

yeah opening a window and finding the camera are 2 seperate things

#

i think you can use a virtual camera for that yes

#

i think this video might be for you

#

yeah that i am still searching for

# 
import cv2
print(cv2.__version__)
#

can you just do this
