Extremely slow hand tracking

[AlexYiningLiu]

The frame rate seems to be extremely slow. As I move my hand across the camera, the display updates not in a smooth manner but very shakily (seems to be low frame rate?) The result is nothing like the once seem in the project description.

Hi, had the same issue. In my case, upgrading to TF2.3 via pip worked. Learned that conda binary had bug. Also, there's a num_threads parameter that can be passed to tf.lite.Interpreter, which is worth trying.
