Some difficultise about python programes provided in data/sintel

[yechaochen]

I have tried to achieve the project but I met some problems when I created the dataset.

I have run the script download_and_create.sh and all of them was smoothly.But I noticed that the data source in the net is point to the folder named sources_18_barron_mit2_sintel_balance but the scipt have not created it.
When I try to run the python programe named create_sintelrs_mit2_barron_split.py and generate_source_full.py.Some errors occured to me.
The line 16 in create_sintelrs_mit2_barron_split.py,the folder sources_18_mask doesn't exist and documents in this folder mentioned in line 32-38 doesn't exist also.And the documents 'albedo_defect_mask_{}' list the images path are not provided in the project.

Does something wrong I did?
