Sorry to bother you again.
When i changed 'train' to ‘generate',and the '--checkpoint_dir=which-pretrained-model-in-checkpoint-dir' becomed 'parser.add_argument('--checkpoint_dir', type=str, default='samples\WGAN-GP\ORDER\ratio-50\orderB007-05-17-20_22\checkpoint\model-97000', help='the saved checkpoint to generate signals')',but i meet the error :UnboundLocalError: local variable 'samples_dir' referenced before assignment.Is it the problem that I modified?
At the same time, I really won't change it'--checkpoint_dir=which-pretrained-model-in-checkpoint-dir'.

1.About the file: samples\ wgan-gp \ORDER\ race-50 \ orderir021-05-17-20_23 \ w-ratio50-order-minmax-or021_98331. out, How is it generated?My run results did not.
2.According to the instructions of "README.md"
$ python train_gan.py --phase='generate' --checkpoint_dir=which-pretrained-model-in-checkpoint-dir --target='B007' --imbalance_ratio=50
About some code changes, how is "--checkpoint_dir=which-pretrained-model-in-checkpoint-dir " changed?
