I am interested in implementing gradient checkpointing to support DialogBERT-XL training. What would the level of effort be with modifying DialogBERT to support an equivalent parameter size as GPT2-XL?

Thanks in advance!

Hi, I found the code was refreshed 15 days ago.

I would like to use this model for a brand new dialogue dataset. I noticed that the data/ have h5 files such as dailydialog/train.h5. I also downloaded the original dailydialog dataset, but I do not know how to parse them to be train.h5.

Could you please share related script or source code please? thank you very much.

I have the following distributed training setup working without issue on Tesla K80, but whenever I attempt to do this with an 8X V100 the training process just silently hangs without dispatching any process to any of the GPUs:

export MASTER_PORT=29500
export MASTER_ADDR="127.0.0.1"
export WORLD_SIZE=8
export RANK=0
python3 main.py --model_size=large --per_gpu_train_batch_size=128 --local_rank 0

What's weird is that training works fine on a single GPU if I drop the --local_rank flag. While the process is just hanging, nothing is being dispatched to any of the GPUs:

Any ideas?

I noticed that the main.py loaded a ./data/dailydialog/train.h5. I also downloaded the original dailydialog dataset. But I have no idea that how to parse them to train.h5.

Could you please give me help?

Hi Xiaodong,

Thanks for sharing the source code.

I have a question regarding data_loader function. Is there any reason to create mini-batches by adding the following inputs?

self.cls_utt = [tokenizer.cls_token_id, tokenizer.cls_token_id, tokenizer.sep_token_id] self.sep_utt = [tokenizer.cls_token_id, tokenizer.sep_token_id, tokenizer.sep_token_id]

The resulting output would be like: [[101, 101, 102], [contexts], [101, 102, 102]].

Best,

Dong

Thanks for your great work! I'd like to apply your method and model to a brand new dataset, but have no idea about how to preprocess our dataset to the required format. Could you release the data preprocessing script? it'll be of great help!

Using the standard main.py training loop, I've been training on V100 tiny for almost a week but without it stopping? Is there additional hyperparameter tuning needed even to run the tiny training process?

python3 main.py --model_size=tiny --per_gpu_train_batch_size=24

avg_len = 12.61646884272997
bleu = 0.03122757749152926
meteor = 0.039703799201764936
nist = 0.12024726693793758
perplexity = 116.93566131591797
rouge-L = 0.05778559382996833
valid_loss = 4.761623978844736

Can you share what your final numbers were after training tiny and small?

I am training on the DailyDialog dataset with the same hyperparameters as described in the paper. I cannot seem to get the model to perform to the standards described in the paper, specifically the BLEU score for the testing data is half the reported value. In addition, looking at the generated text for the testing dataset shows that the model is generating responses that have little to do with the actual context. Are there any solutions to this?

Hi,

I'm trying to reproduce the results you reported in the paper and unable to do so with the set of current hyperparameters. One notable problem is with per_gpu_eval_batch_size=1. Keeping it as is takes a long time to do evaluation, but when I set it to a value > 1, the code breaks. I figured that might have something to do with the generate method of DialogBERT class. Here, for example

generated = torch.zeros((num_samples,1), dtype=torch.long, device=device).fill_(self.tokenizer.cls_token_id) # [batch_sz x 1] (1=seq_len)

num_samples is used as batch_sz? I'm wondering if this is intended, or a typo, because when I change num_samples to batch_sz for generated tokens the code works. However when the generated text shapes up, it doesn't seem to match the context it is generated from.

Could you please share the hyperparameters you used and help solve per_gpu_eval_batch_size=1 problem.

Thanks

Hi again,

I am curious about what methods the paper authors used for context with DialogBERT development? Did you use context prepending of input tokens for that? And how many conversational turns for context were used to obtain the DialogBERT research paper results?

Thanks in advance
