tensorflow.python.framework.errors_impl.NotFoundError: Key is_training not found in checkpoint

Hi Mr.Brightmart @brightmart when I try to run fast text, I got an error like this.

I try to run a01_FastText, steps:

1. python p6_fastTextB_train_multilabel.py everything works fine, then I got fast_text_checkpoint_multi folder with file tree like following: fast_text_checkpoint_multi ├── checkpoint ├── model.ckpt-5.data-00000-of-00001 ├── model.ckpt-5.index ├── model.ckpt-5.meta ├── model.ckpt-6.data-00000-of-00001 ├── model.ckpt-6.index ├── model.ckpt-6.meta ├── model.ckpt-7.data-00000-of-00001 ├── model.ckpt-7.index ├── model.ckpt-7.meta ├── model.ckpt-8.data-00000-of-00001 ├── model.ckpt-8.index ├── model.ckpt-8.meta ├── model.ckpt-9.data-00000-of-00001 ├── model.ckpt-9.index └── model.ckpt-9.meta

2. I try to run python p5_fastTextB_predict_multilabel.py I got following errors:

Could you help me with this, thanks ahead.
