Sorry for being so late, the script should work with Tensorflow 1.x. Are you using Tensorflow 2.0?

It seems it doesn't work with 1.13. It works with 1.12 though.

dataGenSequences.py has minor issues with stride_trick.
As far as I understand, the features are concatenated into a big matrix of features, then the stride_trick reshapes the 2D feature matrix into a 3D tensor in next(). However, this means that the beginning of utt02 will be part of the last few frames in utt01. Likewise, the end of utt01 will be in the first few frames in utt02. This may be acceptable in clean TIMIT experiment since most utterance start/end with silence frames, but it will generate unreliable frames for other corpora (especially those with noisy recordings).

Maybe we need to reshape the utt-level features into 3D tensor first before concat-ing them into a big matrix for feature randomization.
