Some questions about z_cfg #5

Closed jasonchengf closed 6 months ago

jasonchengf commented 6 months ago

Hi, have you tried setting the pred_z_flag and gt_z_flag within z_cfg to True to train and go for evaluation of accuracy? I tried pred_z_flag and gt_z_flag within z_cfg set to True but reported an error, now I'm trying to modify the associated loss for the added z values. If you haven't done the above attempts, can you give me some advice? Really thank you very much!!!

Thanks for your interest, we haven't tried to predict the z values. To support 3D prediction, the computing of geometric representations should be modified. In our method, computing the sine value of the angle between two displacement vectors is required, which is different between 2D and 3D cases.
