Data loss: not sstable (bad magic number): maybe your file is in a different file format and you need to use a different recovery statement?
I am currently training Tensorflow-wavenet with a directory of .wav audio files. Now I want to stop learning and generate output, however the teams do not work. Here is the terminal preparation:

I have seen https://stackoverflow.com/a/167189/2127 , but tf.train.export_meta_graph does nothing. Also, if I try to create output in a new terminal tab, for example:
cd /Users/ruchirbaronia/Downloads/tensorflow-wavenet-master
python generate.py --wav_out_path=generated.wav --samples 16000 logdir/train/2018-01-03T09-18-15/model.ckpt-0.index
I get this error , which basically says that I cannot generate output because the training data was not saved. How can I save and finish training?
