training error

[jeffxsc]

Hi, thank you so much! It is an awesome project!
I'm encountering this error when I try to train the model,
File "train.py", line 47, in
train()
File "train.py", line 19, in train
speech_loader = SpeechLoader(wav_path, label_file, batch_size, n_mfcc)
File "/Users/jeff/Desktop/Tensorflow/wavenet/utils.py", line 30, in init
self.preprocess(wav_path, label_file, wavs_file, vocab_file, mfcc_tensor, label_tensor)
File "/Users/jeff/Desktop/Tensorflow/wavenet/utils.py", line 89, in preprocess
with open(wavs_file, 'wb') as f:
FileNotFoundError: [Errno 2] No such file or directory: '~/wavenet/cache/mfcc60/wavs.file'
It appears right after loading all the audio files. Do you know what may go wrong? Thanks!

just create a mfcc60 folder .
