why the best score can't get 89.2 when I use quora.json5 to train re2?

[chenxichen95]

I use quora.json5 to train a new re2, and use the new model to test. But the acc of quora test set can't get 89.2%.

You should set "eval_file" to "test" (like what "main.json5" does), which evaluates the test set directly in each evaluation during training. This is not what we should do in production, but aligns with previous works and makes the results comparable.

I use "main.json5", and the acc of quora test set can't get 89.2%, only about 84%.

[chenxichen95]

This is the log of training model by using quora.

Did you download the Quora dataset from the link in ReadMe and prepare the data using "prepare_quora.py"?

[chenxichen95]

yes~

[chenxichen95]

Download and unzip Quora dataset (pre-processed by Wang et al.) to data/orig.
cd data && python prepare_quora.py

I did.

Then that's strange... What's your pytorch version? I'll rerun the experiment later

[chenxichen95]

my pytorch version is 1.1.0 . Other dataset can achieve the score in your paper except the quora dataest.

Hi ,I was testing RE2 (Pytorch 1.3.1) on quora dataset, and I got results that were aligned with the paper : Notes :

• I had to use a batch_size=256 as I was facing memory issue with a 1080ti : here is the log of the experiment : https://gist.github.com/jeremypoulain/8ca932a0fc5701578fc4adb127da7adf#file-re2_pytorch_quora_logs-txt
• for the latest versions of Pytorch, you can also modify : mask = torch.matmul(mask_a.float(), mask_b.transpose(1, 2).float()).byte() to mask = torch.matmul(mask_a.float(), mask_b.transpose(1, 2).float()).bool() to get rid of the warning messages. https://github.com/alibaba-edu/simple-effective-text-matching-pytorch/blob/ec89c6486c0e8d2f6ac54c11859a7d5b469afe56/src/modules/alignment.py#L40

Hi ,I was testing RE2 (Pytorch 1.3.1) on quora dataset, and I got results that were aligned with the paper :

I'm trying to reproduce the result on Pytorch 1.5.1 and can confirm that the masking issue is gone with the above fix. I, however, ran into another issue, as below:

    return f'{x:.4f}' if float(x) > 1e-3 else f'{x:.4e}'
TypeError: AverageMeter.__float__ returned non-float (type Tensor)

I'm fairly new to Pytorch and still learning the basics but it does seem like 'model.eval()' was changed somehow, in the newer version. Has anyone encountered this issue before and is there a workaround? Thanks in advance!

@TheMnBN Hi, sorry for the late reply. In pytorch 1.5, the return type of torch.nn.utils.clip_grad_norm_ has change from "float" to "torch.Tensor". Change line 82 of model.py to

'gnorm': grad_norm.item(),

should solve the problem.

Hey, Very Nice Work.

I started training this model and it got failed after few hours giving out of memory error.

result = self.forward(*input, **kwargs)

File "/content/simple-effective-text-matching-pytorch/src/modules/fusion.py", line 50, in forward x2 = self.fusion2(torch.cat([x, x - align], dim=-1)) RuntimeError: CUDA out of memory. Tried to allocate 98.00 MiB (GPU 0; 14.76 GiB total capacity; 12.74 GiB already allocated; 85.75 MiB free; 13.75 GiB reserved in total by PyTorch)

If possible can anyone please provide me the pre-trained model for inference directly?

Thanks in advance!!
