hello,i meet a same question.i send a qq mail for you.

daixiangzi commented 1 year ago

I have solved above problems;

@daixiangzi Hi, can you elaborate on how to solve this problem? I found that pose_feature, posedirs can not be multiplied.

yupei-song commented 1 year ago

I think i found the problem. The gt pose is already rotation matrix，so we did not do batch_rodrigues(). Just reshape the input is OK. And it should be better to add a judgment, whether the input is the representation of the axis angle.
