AssertionError: Selective search data not found at: tf-faster-rcnn/data/selective_search_data/voc_20

I git stash and git pull,
then

rm -rf ./data/cache/./experiments/scripts/train_faster_rcnn.sh 0 pascal_voc vgg16

Now it looks like this:

Change _C.TRAIN.PROPOSAL_METHOD = 'gt' the 118 line in model/config.py file. It should be OK.
We also met with this problem. Very weird.
