How to Fix OpenCV Error: '!_src.empty()' in Hand Tracking Python Code

Hand tracking is a fascinating area in computer vision that allows your Python applications to recognize and follow hand movements in real-time. However, developers frequently encounter an error message while working on these projects:

OpenCV Error: '!_src.empty()'

This error usually indicates that the source image, _src, is empty or unavailable when a particular OpenCV function is called. Here's a guide on how to troubleshoot and resolve this issue when using OpenCV for hand tracking in Python.

Common Causes

Incorrect Image Path
One of the most frequent reasons for this error is specifying an incorrect file path for your source image.

Solution: Double-check the path and ensure that the image or video file exists in the directory you've specified.
