No attribute unpack

I just installed the latest tensor flow from the website and tried running the demo script. Here's the error.

Traceback (most recent call last):
File "simple_demo.py", line 110, in
main()
File "simple_demo.py", line 92, in main
trainable_model = get_trainable_model()
File "simple_demo.py", line 43, in get_trainable_model
learning_rate=LEARNING_RATE)
File "/home/faizan/sequence_gan/model.py", line 72, in init
samples = samples.unpack(self.samples)
AttributeError: 'TensorArray' object has no attribute 'unpack'

Any help?
