Does the skeleton help with training?

Hi,
I’m using DeepLabCut 1.8 and I would like to understand if the skeleton helps during the training or it is just used in the video to plot the line.

Thanks

Hi @Alessandro_Caroti, welcome to the forum!
The skeleton does help during training from the version 2.2 onwards. I’d really encourage you to update :grin:

Hi @jeylau,
thank you very much for the prompt reply :smiling_face_with_three_hearts:!

Is the project created with the version 1.8 compatible with 2.2?

Sure! (You do need a few tweaks though). That page explains the procedure very well https://github.com/DeepLabCut/DeepLabCut/blob/8139a2308c01a4a8a72b9d932f7dfed7d4f5a709/docs/convert_maDLC.md!

even if I don’t use the multi-animal pose estimation?

if you use 2.2b+ then the skeleton is used, independent if you label 1 or more animals, see more here: https://github.com/DeepLabCut/DeepLabCut/blob/dbc5d52dfefa012849f2ca945fb2fb86d3c7b713/docs/UseOverviewGuide.md#important-information-on-using-deeplabcut
