why wider_face_train.mat 's file size is different with the widerface official one?

Dear @Seanlinx I download the anotation files from the widerface's official website, and i find that your wider_face_train.mat in folder "wider_annotations" is different with the official one. i do not know why...

It's a different version of mat file. The one from wider face official site seems in default mat version, which can't be treated as a valid hdf5 file(not accessable for h5py).
