I saw similar issue here but I didn't find a good solution.
I use Google Colab.
Everything went ok till I ran pipeline_test

Python3, gpu

Reproduced on macOS 10.14 (18A391) with Python 3.7.0 installed via Homebrew, following the instructions at https://www.tensorflow.org/install/pip — looks like I need to downgrade to 3.6?

My version of python was 3.6.5 and I installed tensorflow whose version was 1.0. Then I ran the test and no problem appeared.

[Dr-Corgi]

I have found a solution in #285
It work for me.

[TangHan54]

It's a tensorflow version problem. It was built on tensorflow==1.0.0.
To solve it, go to the file seq2seq/contrib/seq2seq/helper.py
change

from tensorflow.contrib.distributions.python.ops import bernoulli
from tensorflow.contrib.distributions.python.ops import categorical
sample_id_sampler = categorical.Categorical(logits=outputs)
sampler = bernoulli.Bernoulli(probs=self._sampling_probability)

to

from tensorflow.contrib.distributions import Bernoulli
from tensorflow.contrib.distributions import Categorical
sample_id_sampler = Categorical(logits=outputs)
sampler = Bernoulli(probs=self._sampling_probability)
