Domain retriever information download

DPR is tested on Python 3. DPR relies on third-party libraries for encoder code implementations. Due to generality of the tokenization process, DPR uses Huggingface tokenizers as of now. Install them separately if you want to use those encoders. First, you need to prepare data for either retriever or reader training.

You can see format descriptions below. One needs to specify the resource name to be downloaded. The resource name matching is prefix-based.

So if you need to download all data resources, just use --resource data. It contains pools of 2 types of negative passages per question, as well as positive passages and some additional information. The preprocessed data available for downloading also contains some extra attributes which may be useful for model modifications like bm25 scores per passage. Still, they are not currently in use by DPR. You can download prepared NQ dataset used in the paper by using 'data.

Those are used for the model evaluation since our NQ preprocessing step looses a part of original samples set. Use 'data. See DPR hydra configuration instructions. Retriever training quality depends on its effective batch size. In order to start training on one machine:. See the section 'Best hyperparameter settings' below as e2e example for our best setups. Generating representation vectors for the static documents dataset is a highly parallelizable process which can take up to a few days if computed on a single GPU.

You might want to use multiple available GPU servers by running the script on each of them independently and specifying their own shards. Git stats 32 commits. Failed to load latest commit information. View code. ProQA 1. Set up the environments 2.
