Codes of LSH|LLSH and light-LSH|LLSH

1. Training
   Run train.sh for training LLSH. Modify this script according to your circumstances.
   Two checkpoints will be saved in ../save.ckpts/1-LLSH/train_mmdd-HHMMSS/checkpoint_0|1.pth.tar (0 for LSH, 1 for LLSH).
   Training logs will be saved in ../save.logs/1-LLSH/train_mmdd-HHMMSS.log.
   You could create a soft link for save.ckpts/ to save the checkpoints in another large-capacity hard disk.

2. Testing
   Run test.sh for testing LSH|LLSH. Append --light option to use light-LSH|LLSH.
   'checkpoint_0.pth.tar' is for LSH and 'checkpoint_1.pth.tar' is for LLSH. Note that the --moco_k option should be consistent with the checkpoint.
   Testing logs will be saved in ../save.logs/1-LLSH/test_mmdd-HHMMSS.log.
   Scores will be saved in ../save.results/1-LLSH/score_dict_mmdd-HHMMSS_0|1.npz.
   LSH|LLSH models will be saved in ../save.results/1-LLSH/llsh_inst_mmdd-HHMMSS_0|1.pth.
