the result of preprocess

[MelvinZang]

When I run preprocess.py in twenty_newsgroup, I get results like these

2 --> SKIP 4 , --> ÉÏ 5 . --> ÉÏ 13 - --> ÉÏ 15 ) --> ÉÏ 16 " --> ÉÏ 17 ( --> ÉÏ 19 : --> ÉÏ 24 ? --> ÉÏ 36 ' --> ÉÏ 43 / --> ÉÏ 49 ! --> ÉÏ 51 ; --> ÉÏ 61 < --> ÉÏ 76 ... --> §£.§£. 79 -- --> -4 90 ] --> ÉÏ 100 max>'ax>'ax>'ax>'ax>'ax>'ax>'ax>'ax>'ax>'ax>'ax>'ax>'ax>'ax --> MalavikaJagannathan?_mjaganna@greenbaypressgazette.com 108 [ --> ÉÏ 126 | --> ÉÏ 226 } --> ÉÏ 231 10 --> -0

I don't know what should I do to fix it,or it is the right results.

[MelvinZang]

I use the results to run lda2vec_run.py

First I get this result:

It is because my chainer version is 3.5.0 and the attribute 'zero_grads' is in the version below 2.0.0. The I change it to optimizer.use_cleargrads() (I'm not sure it is right or not). And then I get this

Does anybody know where the problem is?

[ali3assi]

@MelvinZang the problem is due to the chainer version. change otpimizer.use_cleargrads.

[MelvinZang]

@TamouzeAssi thanks, it is right.

[anupamme]

@MelvinZang I am also running into this assert error:

Traceback (most recent call last): File "examples/hacker_news/lda2vec/lda2vec_run.py", line 87, in words) File "build/bdist.linux-x86_64/egg/lda2vec/topics.py", line 76, in prepare_topics AssertionError: Not all rows in topic_to_word sum to 1

I also had to switch to use use_cleargrads() instead of zero_grads() due to chainer version.

Were you able to fix the assert error: _AssertionError: Not all rows in topic_toword sum to 1

[ali3assi]

@anupamme replace use_cleargrads() with model.cleargrads()

[lovedatatiff]

@MelvinZang Hi! I'm wondering how long did it take you to run preprocess.py and run.py? Thanks!

[MelvinZang]

@lovedatatiff It takes me nearly a whole day to run preprocess.py. But it takes only a few hours to run lda2vec_run.py with GPU

[MelvinZang]

@anupamme another simple way is to change chainer version to 1.9.0

hello @MelvinZang When I run lda2vec.py on my dataset, I get results like these

plz tell,wats happening wrong here? i m stucked.. my dataset contains abstract.txt file (research papers abstracts data)

[ranjeetkgupta]

I am also getting same error AttributeError: 'Adam' object has no attribute 'zero_grads'

has anyone been able to resolve this lately ?

pip show chainer Name: chainer Version: 6.0.0b1 Summary: A flexible framework of neural networks Home-page: https://chainer.org/

Edit : Solved by installing chainer==1.9.0

[MelvinZang]

@stalhaa The results I mentioned in the question are not wrong. It is a conversion process. Words that appear in articles the most are punctuations and the model changes them into something else. When the process continues, it goes normal. You can see plurals turns into singulars and other situation.

I don't understand the results you paste, maybe you can add format so that I can know when and why the model shows things like that.

Hope it helps.

[stalhaa]

plz send me ur email address @MelvinZang .

[ranjeetkgupta]

@MelvinZang . Did you get around the issue by installing chainer version 1.9.0 ? Well, for me it does solve the issue on my mac. But I am trying to setup this on a colab notebook (for gpu support) and unable to install chainer 1.9.0 . *

#################### and with latest version of chainer i get this error. AssertionError: Not all rows in topic_to_word sum to 1)

Really appreciate any insights here !

@MelvinZang ??

[MelvinZang]

@stalhaa Sorry, I forgot. 752087739@qq.com

[stalhaa]

@MelvinZang can u please run your lda2vec.py file code by applying my dataset file instead of twenty_newsgroup and share its results later on.? will u plz do it for me ? I want top words from 100 topics. Kindly help me in this regard.thanks.

[MelvinZang]

@stalhaa let me have a try

[ghost]

My problem is that everytime I install Chainer 1.9.0 in place of a later version, my code can't

import cupy.cudnn

and this cause the

UserWarning: cuDNN is not enabled.

But if I don't switch to 1.9.0 and use a latest version, the

AttributeError: 'Adam' object has no attribute 'zero_grads'

happens. If zero_grads is replaced with use_cleargrads(use=False), use_cleargrads(use=True), use_cleargrads(), or model.cleargrads(), any of them,

AssertionError: Not all rows in topic_to_word sum to 1

shows.
