Loading model fails for book/06.label_semantic_roles

[sanjaymeena]

Hello,

• docker image : paddlepaddle/paddle:0.10.0rc3
• demo : book/06.label_semantic_roles

Issue : Can train model successfully using the provided train.py and the program saves the parameters.
I tried loading the saved parameters using :

from  paddle.v2.parameters import  Parameters 
f="params_pass_2.tar.gz"
parameters=Parameters.from_tar(f)

It fails with following error :

you can use following codes to load the saved parameters:

with gzip.open('params.tar.gz', 'r') as f:
    parameters = Parameters.from_tar(f)

Hi, I am training a Semantic role labeling model on 20k chinese sentences in CONLL2005 format.

docker image : paddlepaddle/paddle:0.10.0rc3
demo : book/06.label_semantic_roles

I am getting following error . Can you help me decipher what may be going wrong. I checked and data format is correct and works for small amount of data ~100 sentences.

Hi, @sanjaymeena

Why not fetch book docker image directly ?https://github.com/PaddlePaddle/book/blob/develop/README.en.md

In this book image, 06.label_semantic_roles has already been verified.

I had tried following images few times before as well just now :

• docker.paddlepaddle.org/book
• docker.paddlepaddle.org/book:0.10.0rc2

I get the same error no module named evaluator :( what is the solution for this?

[gangliao]

please fetch docker.paddlepaddle.org/book:0.10.0rc3, I update it now.

@sanjaymeena You can also run Jupter notebook, because our regression test only covers *.ipynb

[sanjaymeena]

okay. I will try the jupyter notebook as it is still giving me following error :

• I wanted to share that this error is systematic and is occurring when the sentence is the last sentence in the data. The train.py runs till the end of the file data and then while loading next batch throws me the error.
• I will have double checked the conll05 format of my data and it is the same as present in demo program. I will try jupyter to make sure if it is related to paddle or my data.
  Many thanks for prompt response! have been stuck since many days :(

@gangliao I can run the train.py with my data. Turns out problem was with some syntax in data. Thanks for updated book:0.10.0rc3.

Hi, I still got this error using : book:0.10.0rc3. This was after 26th pass. So probably means something wrong with framework??
