None

OS Platform and Distribution

windows 11

MediaPipe Tasks SDK version

No response

python

Describe the actual behavior

Hi @Iamsakir,

Based on the code excerpt provided, it appears that you are using an outdated version of MediaPipe. We have recently launched new MediaPipe Tasks APIs, which are more stable and comprehensive than the legacy version. We strongly advise you to switch to these newer APIs for Hand landmarks, as we no longer provide support for legacy solutions. You can find the Hand Landmarker documentation here.

Thank you!!
