This is a generalized version of PLAID and the previous ColBERT-X for CLIR. The codebase supports models trained with the original ColBERT-X scripts, which are not compatible with the PLAID codebase released from the Stadford Futuredata Group.
We release a set of CLIR models in our Translate-Distill and Multilingual Translate-Distill Huggingface Space. Feel free to try it out!
PLAID-X is available on PyPi. You can install it through
pip install PLAID-X
Make sure your gcc and gxx version is >=9.4.0
, which is the requirement for ninja
to work properly.
We recommend using a conda
environment to control it.
We have published a tutorial on CLIR with notebooks to run various models. Please refer to the PLAID-X notebook there for a simple working example in Python.
The following provides a series of CLI commands for running a larger scale.
The following command starts the training process using the t53b-monot5-msmarco-engeng.jsonl.gz
triple file on the Huggingface Dataset repository hltcoe/tdist-msmarco-scores
with English queries and translated Chinese passages from neuMARCO.
python -m colbert.scripts.train \
--model_name xlm-roberta-large \
--training_triples hltcoe/tdist-msmarco-scores:t53b-monot5-msmarco-engeng.jsonl.gz \
--training_irds_id neumarco/zh/train \
--maxsteps 200000 \
--learning_rate 5e-6 \
--kd_loss KLD \
--only_top \
--per_device_batch_size 8 \
--nway 6 \
--run_tag test \
--experiment test
For training MLIR models using Multilingual Translate-Distill, pass more multiple dataset ids to --training_irds_id
flag along with a --training_collection_mixing
for the mixing strategies (one of entries
, passages
, or round-robin
).
For more details, please read our paper Distillation for Multilingual Information Retrieval(arxiv link TBD).
Since PLAID-X is a passage retrieval engine, you need to create passage collections if you are intended to search a document collection. The following command creates a passage collection for the NeuCLIR1 Chinese corpus (file implicitly downloaded from Huggingface).
python -m colbert.scripts.collection_utils create_passage_collection \
--root ./test_coll/ --corpus neuclir/neuclir1:data/zho-00000-of-00001.jsonl.gz
The indexing processes is broken into three steps. This is changed from the last version where we have two steps and also different from the original Stanford codebase where they combines everything into one Python call. Separating the steps provides better allocation for the computation resources and avoid bad GPU reservation deadlocks between Pytorch and FAISS.
for step in prepare encode finalize; do
python -m colbert.scripts.index \
--coll_dir ./test_coll \
--index_name test_index \
--dataset_name test_coll \
--nbits 1 \
--step $step \
--checkpoint eugene-yang/plaidx-xlmr-large-mlir-neuclir \
--experiment test
done
Note that the --checkpoint
flag accept ColBERT-X and ColBERT models stored on Huggingface Models.
Finally, the following command searches the collection with a query .tsv
file where the first column is the query id and the second column contains the query text.
python -m colbert.scripts.search \
--index_name neuclir-zho.1bits \
--passage_mapping ./test_coll/mapping.tsv \
--query_file query.tsv \
--metrics nDCG@20 MAP R@100 R@1000 Judged@10 \
--qrel qrels.txt \
--experiment test
For replicating PLAID SHIRTTT experiments, we have released the date of each document in NeuCLIR1 and ClueWeb09 on Huggingface. To combine the ranks lists from each shard, you can use the following utility script to do so.
python -m colbert.scripts.shirttt_utils --input {ranking files from each shard} --output {file to write} --topn 50
