Information

Model I am using (Bert, XLNet ...):

facebook/rag-sequence-base

The problem arises when using:

• [x ] the official example scripts: (give details below) examples/rag/finetune.sh

The tasks I am working on is:

• [x ] my own task or dataset: (give details below)

To reproduce

Steps to reproduce the behavior:

run sh finetune.sh with

DATA_DIR=data_dir
OUTPUT_DIR=output_dir
MODEL_NAME_OR_PATH="facebook/rag-sequence-base"

gives:

Model name 'facebook/rag-sequence-base/question_encoder_tokenizer' not found in model shortcut name list (facebook/dpr-question_encoder-single-nq-base).

Expected behavior

finetune.sh should launch and run

Hi, I have a related issue. This happen to "facebook/rag-token-base" and "facebook/rag-token-nq" and "facebook/rag-sequence-nq" as well.

Basic loading failed (was able to do it until around 2 days ago -- I use version 3.5.0) Both

tokenizer = RagTokenizer.from_pretrained("facebook/rag-sequence-nq") and retriever = RagRetriever.from_pretrained("facebook/rag-token-nq", index_name="exact", use_dummy_dataset=True)

result in the same error message:

OSError: Can't load tokenizer for 'facebook/rag-sequence-nq/question_encoder_tokenizer'.

<<< Seem like it add the wrong path question_encoder_tokenizer at the end.

[norakassner]

to add to @ratthachat's comment: I observe the same problem when loading the model with:

model = RagTokenForGeneration.from_pretrained("facebook/rag-token-nq")

[thomwolf]

Tagging @julien-c @Pierrci here. Maybe an issue related to the migration to git/git-lfs

[julien-c]

Initial poster seems to be running transformers version: 3.3.1 which makes me suspect it might not be related to the git/git-lfs migration

Update: @lhoestq is looking into it

[ratthachat]

@lhoestq @julien-c @thomwolf Sorry to ask, but I am translating TFRag and would really love to continue before long hollidays. Could it be possible to fix only the wrong file path (the last question_encoder_tokenizer) in

OSError: Can't load tokenizer for 'facebook/rag-sequence-nq/question_encoder_tokenizer'.

to fix error of basic loading

tokenizer = RagTokenizer.from_pretrained("facebook/rag-sequence-nq")

or

retriever = RagRetriever.from_pretrained("facebook/rag-token-nq", index_name="exact", use_dummy_dataset=True)

or

model = RagTokenForGeneration.from_pretrained("facebook/rag-token-nq")

[ritvik1512]

Apologies for any duplicate comments, but experiencing the same issue as @ratthachat. Any updates or fixes on this? Currently running transformers-3.5.1

[LysandreJik]

Hello, feel free to open a PR with your proposed fix and we'll take a look. Thanks!

[dbarnhart]

Can confirm that this error is eliminated when downgrading to:

transformers==3.3.1
tokenizers==0.9.2
datasets==1.1.2

Looks very likely that something went wrong in the transition to git-lfs for this use case.

@thomwolf @julien-c

[julien-c]

Thanks for the detailed reports everyone, this should now be fixed on master.

Hi I am trying to run use_own_knowledge_dataset.py with Transformers Version: 3.5.1. But it gives the following error.

OSError: Can't load tokenizer for 'facebook/rag-sequence-nq/question_encoder_tokenizer'. Make sure that:

- 'facebook/rag-sequence-nq/question_encoder_tokenizer' is a correct model identifier listed on 'https://huggingface.co/models'

- or 'facebook/rag-seq
```uence-nq/question_encoder_tokenizer' is the correct path to a directory containing relevant tokenizer files

Hey @shamanez - could you open a separate issue for this and tag @lhoestq ? :-)

[shamanez]

Sure :)

[julien-c]

The fix is not yet in a released version only on master, so you need to install from master for now.

[shamanez]

so shall I install from sources?

[norakassner]

Thank you! When will the fixed version be released?
