Pytorch ValueError

[amitsou]

Hi, I'm trying to implement your paper. At this point, I'm trying to use textual information, in order to extract Bert's features. For that reason, I tried executing train_and_validate.py using my dataset. The dataset consists of tweeter comments and their correspondent sentiment (I have 3 classes for sentiment: 0 for negative, 1 for neutral, and 2 for positive). When I execute the following line of code

engine.learn(train_loader,val_loader,model,optimizer,scheduler)

I get the following error:

if size_average is not None or reduce is not None:
2995 reduction = _Reduction.legacy_get_string(size_average, reduce)
2996 return torch._C._nn.cross_entropy_loss(input, target, weight, _Reduction.get_enum(reduction), ignore_index, label_smoothing)
2997
2998

ValueError: Expected input batch_size (4) to match target batch_size (2048).

Can you pls look into that?

I think that the code stops execution when you call on_forward function and more specifically at this point:

self.state['output'] = model

Moreover, why do you use train_loader[0], and why its shape is (4,512)?

Hi @amitsou ,

Thank You for reporting the issue. Let me try reproducing your error. @ramaneswaran @hvarS please see if you can help.

@Sreyan88, where is this paper published? I mean, which journal or conference, Sir?
I want to cite this work for comparison with mine.
please reply asap.
Thanks

@Sreyan88 This is not my question sir, I am asking where is this paper published sir?
regards

[Sreyan88]

it is under review

[Sreyan88]

Extremely sorry for the delay in response. Our paper has been accepted to InterSpeech 2023, and we have pushed new code with improved performance. Please let us know of any bugs that exist.

@Sreyan88 Sorry but stil this code is not working. Could you please tell us how to run this python code locally with Edior? If we could not run it how could we refer this paper?

[Sreyan88]

@Coding511 can you please paste the error? And at which step are you facing the issue?

[Coding511]

@Sreyan88 Thank you for this prompt response sir.
How can I execute this code in Spyder or any editor after saving the code locally?

[Sreyan88]

I would suggest following the instructions in readme and letting us know of any issues from there!

[Coding511]

I have downloaded all the dependencies as mentioned in your readme file. Now how to execute it locally, or in other words is there any way to execute without shell file.
