Hi!
I found that when I load the model back using autoencoder.load_state_dict(torch.load(ae_path))
etc., it leads to low accuracy (around 0.3) even though the model achieves around 0.8 accuracy in evaluate_autoencoder during training.
I have to use torch.load(ae_path)
and torch.save(autoencoder, f)
to get away this problem.
Probably it is a pytorch bug, as discussed here: https://discuss.pytorch.org/t/saving-and-loading-a-model-in-pytorch/2610/6
Hello I'm looking at the experiments section and a script called walk.py
is mentioned in the README, but it seems to be missing.

hi,
I download your given max-length-15 model, and run this code, but the result is very bad:
Sentence interpolations:
A Asian Lady A There
A An A A A
A An A A A
The The A A A
The A a someone A
couple black pushes skinny is
brown Asian woman female child
brown Asian man female child
yellow female man girl couple
fence young man is couple
fishes dog an asleep the
dog black swings surfing is
dog child eats is is
dog player a is wearing
plays lady plays playing wearing
as you see, I even can't generate normal sentence, so I just wonder why I didn't get good result.
is that because of the model, or I need to run many times to get good result?
I am wondering how to use this code to perform the "offset vector transformation" examples in the paper, such as substituting "clapping" with "walking" and altering the entire input sentence to fit the new word.
In the README
there's no mention of how you generate the train.txt and test.txt for the OneB dataset. Could you clarify how do you do that?
Thanks!
Hi
Should this https://github.com/jakezhaojb/ARAE/blob/master/pytorch/experiments/vector.py#L71 be np.mean(means, axis=0)
?
I found that the provided weights work quite well when I generate samples.
However, if I train the model with the provided script(the same setting), the result is very pool.
Are there any changes in the code?
According to the Algorithm1 in the paper, L_G=errG_real-errG_fake.
However, in your pytorch implementation, only errG_fake is backpropagated.
Why? How does it affect the performance if you backpropagate both?
When using the following command for training:
python train.py --data_path PATH_TO_PROCESSED_DATA --enc_grad_norm False
"enc_grad_norm" is still "True". Should this be fixed in this way?
Hi, when I run run_snli.py, it does not work. :'(
python run_snli.py --data_path ./data/snli_lm --no_earlystopping
then..I encountered the TypeError as below. Do you know any solutions?

TypeError: normal() received an invalid combination of arguments - got (means=Tensor, std=float, ), but expected one of:
Line 242-244 function evaluate_autoencoder
, train.py
:
all_accuracies += \
torch.mean(max_indices.eq(masked_target).float()).data[0]
bcnt += 1
Since masks in batches are different, in each batch there'll be a different number of indices being compared. The average of average is equal to the average of all if and only if all the chunks are of the same size, which is not the case here. The all_accuracies
calculated here is inaccurate.
Besides, in line 233 in function evaluate_autoencoder
, train.py
:
output = autoencoder(source, lengths, noise=True)
During the evaluation, the autoencoder seems to be "cheating" here. The correct word vector of the last word is given, and this is not the case when the autoencoder is doing the real inference. The actual accuracy will be a lot lower. The sentence-level accuracy is way lower than word-level accuracies as well. When the decoder fails to generate "<eos>", the whole sentence is wrong, but in word-level accuracies, the sentence is (n-1)/n correct.
In the paper the semi-supervised learning is described. How can I use this code to do the semi-supervised tasks?
Kindly suggest how to generate sentences (after training) conditioned on a label for eg., positive sentiment along with the conditioning on latent z.
I got this error while training a full model yesterday:
Traceback (most recent call last):
File "train.py", line 526, in <module>
train_gan_d(train_data[random.randint(0, niter)])
IndexError: list index out of range
This happened for the last batch of the last epoch.
The relevant code block:
# train gan ----------------------------------
for k in range(niter_gan):
# train discriminator/critic
for i in range(args.niters_gan_d):
# feed a seen sample within this epoch; good for early training
errD, errD_real, errD_fake = \
train_gan_d(train_data[random.randint(0, niter)])
It is possible that train_data
can be populated with less elements than niter
in the batchify
function?
The argument list I had was pretty minimal: python train.py --data_path /path/to/billion-word-data --cuda --no_earlystopping
I found that in the function train_gan_d(),
the loss_fake and loss_real are in the opposite direction with the original paper.
I was wondering is it correct or not?
With the current code structure, evaluation and saving of the models only happens when the --no_earlystopping
is not provided.
Ideally we would like some form of evaluation to happen even when not using LM (not sure if possible) and perhaps saving the models at the end of each epoch regardless of the arguments provided.
Since this should be a simple change, let me know if you are currently open to accepting PRs.
