💡 Hint

Common Mistakes

Using 'mp_pose' or 'pose' as the alias instead of 'mp'.

Trying to import 'mediapipe_pose' which is not a valid module.

The correct import alias for MediaPipe is mp. This is the standard convention used in MediaPipe examples.

💡 Hint

Common Mistakes

Using 'img' or 'frame' without defining them.

Passing 'video' which is not a single image.

The variable holding the image to process should be named image as per the example context.

💡 Hint

Common Mistakes

Using 'draw_pose' which is not a valid function.

Using 'landmarks' instead of 'pose_landmarks' attribute.

The function to draw landmarks is draw_landmarks, and the pose landmarks are accessed via pose_landmarks.

💡 Hint

Common Mistakes

Using 'lm.name' which is not an attribute of landmarks.

Confusing the variable names in the comprehension.

The dictionary uses the landmark index i as key. The y-coordinate is accessed with y. The landmarks list is landmark.
