Models: ptb_word_lm.py AttributeError: 'module' object has no attribute 'RNNParamsSaveable'

[larryfu]

when running ptb_word_lm.py with tf-nightly 1.5.0-dev20171103
I got this error

It seems that there is no RNNParamsSaveable in cudnn_rnn
Any idea how to fix it?

[angerson]

Please provide details about what platform you are using (operating system, architecture). Also include your TensorFlow version. Also, did you compile from source or install a binary? Make sure you also include the exact command if possible to produce the output included in your test case. If you are unclear what to include see the issue template displayed in the Github new issue template.

We ask for this in the issue submission template, because it is really difficult to help without that information. Thanks!

https://github.com/tensorflow/tensorflow/commit/b30ce471420384b931ba40fa21ba8838f12a79eb changed RNNParamsSaveable into multiple classes, and ptb_word_lm hasn't been updated yet. @ebrevdo, can you take a look?

[David-Levinthal]

can somebody offer a suggestion on how to change the following block from ptb_word_lm.py (or should this just be commented out). It would be interesting to compare the cuda9/cudnn7 r 1.4 build with the older R1.3 cuda8/cudnn6 buiild
rnn_params = tf.get_collection_ref("rnn_params")
if self._cell and rnn_params:
params_saveable = tf.contrib.cudnn_rnn.RNNParamsSaveable(
self._cell,
self._cell.params_to_canonical,
self._cell.canonical_to_params,
rnn_params,
base_variable_scope="Model/RNN")
tf.add_to_collection(tf.GraphKeys.SAVEABLE_OBJECTS, params_saveable)

[David-Levinthal]

commenting out the if block and the tf.add_to_collection line will get the code to run

[withme6696]

I change the code as follows, then it works:
if self._cell and rnn_params:
params_saveable = tf.contrib.cudnn_rnn.CudnnLSTMSaveable(
rnn_params,
self._cell.num_layers,
self._cell.num_units,
self._cell.input_size,
self._cell.input_mode,
self._cell.direction,
scope="Model/RNN")
remove this line"tf.add_to_collection(tf.GraphKeys.SAVEABLE_OBJECTS, params_saveable)"

please help me to solve this issue . its kinda urgent . i am trying implementing on cpu version . and here is the code link on tensorflow to which i am trying to execute . " https://www.tensorflow.org/tutorials/recurrent" .

[David-Levinthal]

This is a different issue.
I believe you have either built, installed a cuda build of TF. You need one
built for a CPU. Possibly with MKL.

Or you just run with the extra command line argument

--num_gpus=0

?

i can't able to understand anything . whats going on . because i am tried all possible way to resolve it . let me tell you the complete process . i have downloaded and install anaconda and the tensorflow packages to run the recurrent neural network code given on the tensorflow website . and when i execute the code using anaconda tensor flow environment and then the output what i got was above .

[David-Levinthal]

did you add the --num_gpus=0
flag to the invocation?
you are getting the most recent version of PTB, thus you will also have to
do the edits to the code specified by withme6696 near the top of this bug
report to get it to run.
I did what he said and it works
and I suspect you need to be using TF R1.4 to have the new APIs that are
invoked

have to submit it to the company where i applied for internship . please
help me if anyone could do it !

ok . Thank you so much ! but i can't able to still resolve it . i will

if you could do it ! this internship really matters for me and last chance
to get internship for next 6 months . i need to submit the outcome only .

here is the link and we have to execute the command in "run the code"
section.
