Hi,

I've been reading the ViLT paper and was impressed by the simplicity, as it only adds text embeddings to a ViT.

As ViT is already available in HuggingFace Transformers, adding ViLT should be relatively easy.

I've currently implemented the model (see here for my current implementation). It includes a conversion script (convert_vilt_original_to_pytorch.py) to convert the weights from this repository (the PyTorch Lightning module) to its HuggingFace counterpart, for all models (base one + the ones with a head on top).

However, I'm facing some issues when performing a forward pass with the original implementation in Google Colab (when just doing pip install -r requirements.txt and running the demo_vqa.py script, you get the following):

Traceback (most recent call last):

If you suspect this is an IPython bug, please report it at:

or send an email to the mailing list at [email protected]

You can print a more detailed traceback right now with "%tb", or use "%debug"
to interactively debug it.

Extra-detailed tracebacks for bug-reporting purposes can be enabled via:
    %config Application.verbose_crash=True

Upgrading PyTorch Lightning to the latest version also returns an error:

As PL deprecated the metrics module.

Are you able to provide a simple Colab notebook to perform inference on an image+text pair?

Thanks!

Hi, @dandelin

When I turn on the mpp (Masked Patch Prediction), I get this error:

AttributeError: 'VisionTransformer' object has no attribute 'mask_token'

The above error is appear in vision_transformer.py. Could you please tell me how to address it?

Thank you for your help.

Best regards, Ge-Peng.

Dear Authors, Thanks for open sourcing the code. I tried pretrain 100k steps and finetune on vqav2, but my dev-test score is about 65, unlike the 70.8 on the paper.

Here is my pretrain and finetune command

python run.py with data_root=vilt_dataset/ \
	num_gpus=8 num_nodes=8 task_mlm_itm whole_word_masking=True step100k \
	per_gpu_batchsize=64 exp_name=pretrain

	exp_name=vqa_finetune

Hello,

I have read through your code, but haven't run the code yet. One question about the dataloader implementation. According to

https://github.com/dandelin/ViLT/blob/master/vilt/datasets/base_dataset.py#L43

You load all the arrow files into memory. The pre-training data have hundreds of gigabytes. Is it possible that this may cause out-of-memory issue? Or does this implementation assume large machine memory?

Thanks,

I run into an error

In Image Retrieval, the [email protected] is 68.4 which is higher than 61.9 in paper In Text retrieval, the [email protected] is 73.5 which is lower than 81.4 in paper

So, I want if the input format is error in my code.

In image, I use "pixelbert_transform" function of size=384. In Text, I use Bert base tokenizer with max len 40 which includes [CLS], word tokens and without [SEP]. In flickr-30k, I use dataset_flickr30k.json to get test datasets, and I chose the first caption of five about each image.

Thanks very much for your help!

Hello, thanks for the amazing repository. If I understand correct, for IRTR, answer should be 1 for the first element which is true, and 0 for the remaining false texts (https://github.com/dandelin/ViLT/blob/master/vilt/modules/objectives.py#L429)

But in the code, it sets all of them including the positive sample to be zero. Am I missing something here? Thanks!

Hi, @dandelin Thank you for your interesting work, I am runing demo_vqa.py and failed at line 38 https://dl.dropboxusercontent.com/s/otya4i5sagt4f5p/vqa_dict.json, because this link is unavailable now. Do you download this file? Also, vilt_200k_mlm_itm.ckpt link is already unavailable... Wishing for your reply!

Hello again @dandelin ,

I was trying to reproduce the steps from https://github.com/dandelin/ViLT/blob/master/EVAL.md to get the results from Flickr30k T2IR.

First I did what is suggested in https://github.com/dandelin/ViLT/blob/master/DATA.md.

So I have in a folder /content/flickr30k this structure:

    /content/flickr30k
     ├── flickr30k_images            
     │   ├── ....jpg
     |   ├── ....jpg
     ├── karpathy          
         ├── dataset_flickr30k.json              

Then I do the transformation:

from vilt.utils.write_f30k_karpathy import make_arrow
make_arrow( '/content/flickr30k',  '/content/arrow')

But when I run:

python run.py with data_root='/content/arrow' num_gpus=1 num_nodes=1 per_gpu_batchsize=4 task_finetune_irtr_f30k_randaug test_only=True load_path="/content/TFM_Sparse_Embeddings/vilt_irtr_f30k.ckpt"

I get the error:

Thanks for your paper and code, it helps me a lot. There is a small problem that makes me feel confused. In your paper 3.1, the text embedding consists of word embedding, position embedding, and modal-type embedding.

while in the source code of vilt/modules/vilt_module.py, the text_embedding is implemented by:

from transformers.models.bert.modeling_bert import BertConfig, BertEmbeddings
...
  self.text_embeddings = BertEmbeddings(bert_config)

and an extra token_type embedding self.token_type_embeddings = nn.Embedding(2, config["hidden_size"]) As I know, BertEmbedding() already contains a token type embedding operation inside, so there are actually two token type embedding for text input, and one token type embedding for image input. I know the self.token_type_embeddings is used as the modal_type embedding to distinguish between image and text. Is it a mistake? Is it ok not to remove the token type embedding inside BertEmbeddings(bert_config)? Will it cause any difference? Hope for your reply, thanks!

Hey, I runned demo_vqa.py and did something more. And what I found is that the "ids" in vqa_dict.json (which is download from this URL:"https://github.com/dandelin/ViLT/releases/download/200k/" in the file demo_vqa.py ) misses the id :"125". That means the id jumps from "124" to "126", which caused some bugs . Can you please check the issue and tell me what's the original answer pair with the id "125" ? Thanks a lot !

Hello, what configuration does your vilt use when fine-tuning flickr30k? Eight gpus? What is the memory of each gpu? What is the result of fine-tuning flickr30k? Is it a weight file?
