I am facing the same issue when executing STFT_feature_extractor.ipynb file.

FileNotFoundError                         Traceback (most recent call last)

     16                 print(subject,activity,file)

Could someone please help?

you have to create /STFT_features/stft_257_1' directory manually and save s01-s17 all audio files
