indic-bert-v1's Issues

Is there any documentation as how to implement Q&A and NER using indic-bert ?

Can someone please share link of a notebook or documentation with one example of how to use indic-bert for Q&A and NER ?

Hey, I am working on adding support for specifying custom dataset. Will revert in a couple of days

Hi there I was wondering if there is such a feature. If so, how I can use the fine tuning on google colab with new dataset. "Hey, I am working on adding support for specifying custom dataset. Will revert in a couple of days"
Thanks

Documentation to implement model on an external dataset

Hi All,

Is there any documentation to train the model on our own dataset ... I wanted to know what dataset format the model takes and how we can fine-tune the model based on that dataset.

finetuning.ipynb - Colab is broken

Greetings,

Thank you for this excellently documented package. I am having some trouble getting the Collab to run step 4, Fine-tune the Model. Here is the output:

/content/indic-bert/indic-bert
/usr/local/lib/python3.6/dist-packages/transformers/modeling_auto.py:798: FutureWarning: The class 'AutoModelWithLMHead' is deprecated and will be removed in a future version. Please use 'AutoModelForCausalLM' for causal language models, 'AutoModelForMaskedLM' for masked language models and 'AutoModelForSeq2SeqLM' for encoder-decoder models.
  FutureWarning,
Some weights of the model checkpoint at ai4bharat/indic-bert were not used when initializing AlbertForMaskedLM: ['sop_classifier.classifier.weight', 'sop_classifier.classifier.bias']

Error in loading the model from huggingface transformers

Thank you for your work! I'm loading the model from huggingface transformers and am running into the following error:

RuntimeError: Error(s) in loading state_dict for AlbertModel:
size mismatch for albert.embeddings.position_embeddings.weight: copying a param with shape torch.Size([512, 128]) from checkpoint, the shape in current model is torch.Size([128, 128]).

The error occurs when I load the model as follows:
model = AutoModel.from_pretrained("ai4bharat/indic-bert")

Please let me know if you need any more information.Thanks!

Documentation to implement NER

Hey,
I tried using IndicBert NER for news article clustering using transformers. While tokenization, some of the tokens are getting split up. I wanted to know if there is any way to avoid it.
Also, when I implemented the same example as you have mentioned in your documentation, I get different results.


kindly help me on why the tokens are not getting recognized properly. When I tried giving custom inputs in the same format of the tokenizer, tokens are not getting recognized and giving encoding as 1 even with add_special_token.

It would be helpful if you could share some implementations of the NER.

Finetuning on IndicGlue News Headline Prediction Task

I'm trying to find the IndicGlue dataset to finetune on the news headline prediction task using finetune.cli.py but I'm not able to find the IndicGlue dataset. Can someone please guide me with this?

Tokenization doesn't preserve diacritics

I was working recently with the IndicBERT SentencePiece tokenizer and found something which I was curious about. It turns out that when we encode sentences, a good amount of diacritics do not get encoded. So for example, in Hindi, the sentences - "मेंने उसकी गेंद दी।" and "मैने उसको गेंद दी।" have the same encodings despite one having the genitive and the other the dative marker. I have seen this for Gujarati and Hindi. The reason I think the diacritics are ignored is that when the encodings are decoded, some diacritics are missing.

I was curious to know why this happens and if there is a work-around.

Regarding IndicBERT fine tuning and Evaluation splits

Hi, Thanks for this great repo and initiative. I have a question about IndicBERT evaluation. I read from that the paper that IndicBERT was fine tuned on the following datasets: –CVIT-MannKiBaat–WNLI–COPA–Amritha–MIDAS Hindi Discourse–IIT-Patna Movie and Product Sentiment Analysis (Hindi)–ACTSA Sentimenet analysis corpus (Telugu).

However in evaluation results of IndicBERT, I see again the same datasets references (Referring to the "Table 9" of the IndicNLPSuite paper). Could you please let know if this was done after splits? If yes, is it possible to please let know the splits. Please let me know in case I have overlooked something. Thank you.

Cannot instantiate Tokenizer

I am using Huggingface Transformers 4.0.0. When I instantiate the autotokenizer for indicbert, I get the following issue:

My code:
tokenizer = AutoTokenizer.from_pretrained('ai4bharat/indic-bert')

Error:
Couldn't instantiate the backend tokenizer from one of: (1) a tokenizers library serialization file, (2) a slow tokenizer instance to convert or (3) an equivalent slow tokenizer class to instantiate and convert. You need to have sentencepiece installed to convert a slow tokenizer to a fast one.

What is special in IndicBERT compared to other models?

Documentation for IndicGLUE

Hi,

This repository has some great resources!

I was wondering where the documentation for the fine-tuning datasets are. Sorry if I overlooked something obvious.
I want to evaluate my models (not IndicBERT) on your dataset, so wanted to see how that is possible.

Thanks!

How to decode token embeddings into token ids?

I'm trying to build a machine translation model using the indicBERT model as an embedding. I'm able to obtain token embeddings from a tokenized sentence as follows:

tokenizer = AutoTokenizer.from_pretrained('ai4bharat/indic-bert') 
model = AutoModel.from_pretrained('ai4bharat/indic-bert')

vocab_to_embedding_convertor = model.get_input_embeddings()
tokens = tokenizer(["హలో","పేరు"], return_tensors="pt")['input_ids']

embeddings = vocab_to_embedding_convertor(tokens)

However, I'm unable to find a way to obtain token ids from these embeddings. How would I go about doing this?

Thanks!

Error during downloading the en-indic dataset

Getting the above error while trying to download the en-indic dataset.

Tokenization issues

Running into some potentially troublesome issues in the tokenization for indic-bert. It seems all vowel matras (diacritics) are getting dropped in the tokenization, which loses a lot of information about the word. Perhaps some sort of Unicode issue?

Minimal example (prints True) where two very different words get treated as the same token.

import transformers
tokenizer = transformers.AutoTokenizer.from_pretrained('ai4bharat/indic-bert')
print(tokenizer.tokenize("यहाँ") == tokenizer.tokenize("यह"))

bert-base-multilingual-cased does not have this issue.

Is this an issue on my end? I have this problem on Colab and on my machine (Mac, Python 3.8.8). @nitinvwaran also has this issue. I had to install sentencepiece to get the tokenizer to work btw.

Unable to download the BBC News dataset

Hi, I'm trying to train the model for classification on the BBC News dataset.

When I' visiting this link, getting the below error.

Is there a plan to reinstate the dataset?
Also, can the weights of the model trained on this dataset be released?

Error encountered while training IndicBert on cvit-mkb dataset

Hi Authors,
First of all, It's great to have GLUE benchmarks for Indian languages, and thanks for the great effort.

Problem faced:
While executing the code for cvit-mkb (mann-ki-baat) dataset, I faced an issue. It seems like the ManKiBaat Dataset processor module doesn't have the method named: get_labels due to which the code terminates.

To get the inference results, I have used the following command:
argvec = ['--lang', 'hi',
'--dataset', 'cvit-mkb',
'--model', 'ai4bharat/indic-bert',
'--iglue_dir', '../indic-glue',
'--output_dir', '../outputs',
'--max_seq_length', '128',
'--learning_rate', '2e-5',
'--num_train_epochs', '3',
'--train_batch_size', '32'
]

finetune_main(argvec)`

I have another concern regarding the cvit-mkb dataset for cross-lingual sentence retrieval. In the ManKiBaat Dataset processor module only supports 'en' and 'in' modes but there is no such Unicode available for any of the languages mentioned in the IndicNLPSuite paper.

I am also attaching the error logs which I encountered during the inference:

ValueError: Shape of variable bert/embeddings/LayerNorm/beta:0 ((768,)) doesn't match with shape of tensor bert/embeddings/LayerNorm/beta ([128]) from checkpoint reader.

when i used model.ckpt from pretrained IndicBERT then i got this error

why it is occuring

Need documentation in using the model

Hi,
I would like to use this model for extracting word vectors for Telugu text.
I am looking for code snippets on how to use the model for extracting word vectors. Can you please help with this? Or if there is any documentation available on using the model in Hugging Transformers, please share the same.

Thank you in advance

How do I use this in a sentence transformer?

I used a basic sample with SentenceTransformer to find the text similarity, but the text is in tamil language, i used this model, but not able to find matches for simple words too.
