opencv read function is just working well from python idle shell works bad from python image handler

OpenCV is a powerful library used for computer vision tasks in Python. The read() function in OpenCV is commonly used to read and load images or videos. However, sometimes issues arise when using this function in different Python execution environments like the Python IDLE shell or a script (image_handler.py).
Here's an informative tutorial that explains the potential reasons why the read() function might behave differently in these environments and how to troubleshoot such issues:
cv2.imread() is an OpenCV function used to read an image from the specified file path. It loads the image as a NumPy array, which can be processed or manipulated using OpenCV functionalities.
The read() function might exhibit different behavior when used in Python IDLE compared to a Python script (image_handler.py). Some potential reasons for this inconsistency include:
To check the working directory in Python, use:
Example of loading an image using an absolute path:
Ensure that the script (image_handler.py) has the necessary permissions to read files from the specified directory. Permissions might differ based on the user running the script and the environment.
Understanding the behavior of the read() function in different Python execution environments is crucial for troubleshooting issues related to image loading in OpenCV. By checking the working directory, verifying file paths, and ensuring proper permissions, you can resolve inconsistencies in cv2.imread() behavior between Python IDLE and script execution.
Feel free to modify the script (image_handler.py) accordingly based on the troubleshooting steps provided to ensure successful image loading using OpenCV's read() function.
