Import errors with tensorflow version 0.12.1

[mads14]

Hi,

I just cloned your repo and downloaded tensorflow version 0.12.1. I am trying to run your example code. I am getting errors on the imports:

Traceback (most recent call last):
File "main.py", line 5, in
from trainer import Trainer
File ".../pointer-network-tensorflow/trainer.py", line 7, in
from model import Model
File ".../pointer-network-tensorflow/model.py", line 4, in
from layers import *
File ".../pointer-network-tensorflow/layers.py", line 7, in
LSTMCell = rnn.LSTMCell
AttributeError: 'module' object has no attribute 'LSTMCell'.

From looking at the tensorflow docs it seems that LSTMCell is now located at:
tf.nn.rnn_cell.STMCell. I changed the code to read: LSTMCell = tf.nn.rnn_cell.LSTMCell and made a similar change for the next line of layers.py: MultiRNNCell = tf.nn.rnn_cell.MultiRNNCell.

I'm now getting a similar error on the seq2seq line, and can't figure out how to fix it:
Traceback (most recent call last):
File "main.py", line 5, in
from trainer import Trainer
File ".../pointer-network-tensorflow/trainer.py", line 7, in
from model import Model
File ".../pointer-network-tensorflow/model.py", line 4, in
from layers import *
File ".../pointer-network-tensorflow/layers.py", line 9, in
dynamic_rnn_decoder = seq2seq.dynamic_rnn_decoder
AttributeError: 'module' object has no attribute 'dynamic_rnn_decoder'

It seems that tensorflow.contrib.seq2seq exists but does not have a dynamic_rnn_decoder function in version 12.1.0? Can you confirm that this is still working on your version and that you are in fact using tensorflow version 12.1.0.

Thanks!

It seems that tf 0.12.1 doesn't have dynamic_rnn_decoder or simple_decoder_fn_train, I made it work on tf 1.0.0.

In layers.py:
replace

LSTMCell = rnn.LSTMCell
MultiRNNCell = rnn.MultiRNNCell
dynamic_rnn_decoder = seq2seq.dynamic_rnn_decoder
simple_decoder_fn_train = seq2seq.simple_decoder_fn_train

to

LSTMCell = tf.contrib.rnn.LSTMCell
MultiRNNCell = tf.contrib.rnn.MultiRNNCell
dynamic_rnn_decoder = tf.contrib.seq2seq.dynamic_rnn_decoder
simple_decoder_fn_train = tf.contrib.seq2seq.simple_decoder_fn_train

In model.py: change all tf.concat_v2 to tf.concat.

After that, it will still complain that tf.contrib.layers doesn't contain utils. I modified site-packages/tensorflow/contrib/layers/__init__.py, adding 'utils' into _allowed_symbols, and it worked. Perhap there is a better way to do this.

I changed file model.py as link, and it worked with tensorflow v1.0 without any modification in tensorflow library.

why did you close this issue? I still have the same problem
