Long-Range Arena (LRA: pronounced ELRA).
Long-range arena is an effort toward systematic evaluation of efficient transformer models. The project aims at establishing benchmark tasks/dtasets using which we can evaluate transformer-based models in a systematic way, by assessing their generalization power, computational efficiency, memory foot-print, etc.
Long-range arena also implements different variants of Transformer models in JAX, using Flax.
This first initial release includes the benchmarks for the paper "Long Range Arena: A benchmark for Efficient Transformers.
Currently we have released all the necessary code to get started and run our benchmarks on vanilla Transformers.
We are working on a 2nd update that will release more models and baselines for this benchmark suite. Stay tuned.
Please see below for more examples on how to get started.

A note on evaluation and comparisons
Apples-to Apples setting
This setting is for folks who want to compare with our published results directly.
The default hyperparameter setup (each benchmark should have a config file now). You are not allowed to change hyperparameters such as embedding size, hidden dimensions, number of layers of the new model.
The new model should be within at best 10% larger in terms of parameters compared to the base Transformer model in the provided config file.
Free-for-all Setting
You are allowed to run any model size and change any hyperparameter of the model. However, in the end, you'll not be allowed to report results from our leaderboard because they are no longer comparable. You can choose to rerun models from our library in a comparable setting.
Adding benchmarks or models to this suite
If you develop or could benefit from an extensive array of xformer baselines, please feel free to let us know if you're interested in building new benchmarks. We welcome contributions for new or older models that are not covered in the existing suite.
Example Usage
To run a task, run the train.py file in the corresponding task directory. (please see how to obtain the data for certain tasks if applicable).
PYTHONPATH="$(pwd)":"$PYTHON_PATH" python lra_benchmarks/listops/train.py \
--config=lra_benchmarks/listops/configs/transformer_base.py \
--model_dir=/tmp/listops \
--task_name=basic \
--data_dir=$HOME/lra_data/listops/
Dataset Setup
This section describes the methods to obtain the datasets and run the tasks in LRA.
To download the datasets, please download it from
gs://long-range-arena/lra_release
. If permissions fail, you may download the
entire gziped file at
https://storage.googleapis.com/long-range-arena/lra_release.gz.
ListOps
This task can be found at /listops
. The datasets used in our experiments can
be found at these google cloud buckets and are in TSV format.
If you would like to go to longer/shorter sequence lengths, we also support generating your own split, run the following comment:
PYTHONPATH="$(pwd)":"$PYTHON_PATH" python lra_benchmarks/data/listops.py -- \
--output_dir=$HOME/lra_data/listops/
Text Classification
This task can be found at /text_classification
. No action is required because
this task is already found in tensorflow datasets. The code should run as it is.
Document Retrieval
Please download the dataset at (http://aan.how/download/). Please download the
train/test/dev splits from our google cloud bucket. Unfortunately, we were not
able to re-distribute this datasets and are only releasing the ids in the format
label paper1_id paper2_id
. You may download the data from the original source
and extract the textual data.
Pixel-level Image Classification
This task can be found at /image
. No action is required because this task is
already found in tensorflow datasets. It should work out of the box.
Pathfinder
Please see the ./data
directory, where the TFDS builder for the pathfinder
dataset can be found. We generated different datasets for pathfinder task, with
different levels of difficulty using the script provided
here. You can find information
about the parameters used for generatinng the data in the TFDS builder code in
./data/pathfinder
. We are preparing the exact data splits for release at the
moment.
