Q:

Tensorflow rnn: name 'seq2seq' is not defined

I am trying this notebook:
https://github.com/sjchoi86/Tensorflow-101/blob/master/notebooks/char_rnn_sample_tutorial.ipynb
I have a problem with this line In[6]:
outputs, final_state = seq2seq.rnn_decoder(inputs, istate, cell, loop_function=None, scope='rnnlm')

I get this error: 
NameError: name 'seq2seq' is not defined

I am using tensorflow 1.0.1. I tried 
tf.contrib.seq2seq

but I am getting error:  
AttributeError: 'module' object has no attribute 'rnn_decoder'

I think it is a probleme with the new implementation of rnn network in tensorflow 1.0.1 but I don't know how to fix it.

A:

Because seq2seq has been moved to tf.contrib.legacy_seq2seq. You should change this line to:
outputs, final_state = tf.contrib.legacy_seq2seq.rnn_decoder(inputs, istate, cell, loop_function=None, scope='rnnlm')
