Type issue when initializing features

I am using the Toolkit in a clustering algorithm with Tensorflow (see https://github.com/BinRoot/TensorFlow-Book/blob/master/ch05_clustering/Concept01_clustering.ipynb).
When the last cell runs, I get this error :

Loading ./audio_dataset/cough_1.wav
INFO:tensorflow:Error reported to Coordinator: <class 'tensorflow.python.framework.errors_impl.CancelledError'>, Enqueue operation was cancelled
[[Node: input_producer/input_producer_EnqueueMany = QueueEnqueueManyV2[Tcomponents=[DT_STRING], timeout_ms=-1, _device="/job:localhost/replica:0/task:0/cpu:0"](input_producer, input_producer/RandomShuffle)]]

I've checked and I am using the last update of the BregmanToolkit. Does anybody know how to fix that ?

Documentation needs updating

The tutorials need some updating. Keyword arguments for features are now expanded python dicts, using the **kwargs syntax.

E.g. the following feature instances are equivalent:
LinearFrequencySpectrum(audio_dir+'fastcar.wav', nfft=2048, wfft=1024, nhop=512)
LinearFrequencySpectrum(audio_dir+'fastcar.wav', **{'nfft':2048, 'wfft':1024,'nhop':512})

Python 3 support needed

Any chance support for python3 is in the works? When I try to install I get the following:
