I do not understand the usage of this parameter in oxford.yaml...

train_fea_dir: "/data/features/best_features/paris" # path of the features for training SVD.

I find this in oxford.yaml, and it is strange that when I run main/index.py, the shell post a error:
[LoadFeature]: loading feature from /mnt/ceph/home/richardzuo/wx_yszm/ft_local/PyRetri-master/features/oxford/query/part_0.json...

can you explain it ? thanks~
