Error in preprocessing_train.py

[sebo361]

Hi @classner, great work!

I am currently working on human pose estimation and i want to train my model on a specific activity of MPII human pose dataset. Therefore I am looking for a script which converts the .mat file with MPII human pose annotations to a .csv file, so i then can delete the not desired activities manually. While searching i found your preprocessing_train.py script but unfortunately i get following error when running it: IndexError: only integers, slices (:), ellipsis (...), numpy.newaxis (None) and integer or boolean arrays are valid indices
I use python 2.7 - do you know how to solve this issue?

Or do you have a better idea for solving my goal of minimizing the MPII data set to a specific activity?

Thanks and best,
Sebastian
