What this file does
Walks a project admin through checking out, testing, uploading, and merging a dataset pull request in the BigScience biomedical repository.
When to use it
- You are a project admin reviewing a dataset PR in a biomedical hub
- You need to run unit tests on a new or updated dataloader
- You must upload a dataset to a Hugging Face hub as part of a PR workflow
- You want to merge a PR after all checks pass

Review Guide
This guide explains what steps a project administrator needs to perform when updating a dataset implementation.
Checkout PR
First, checkout the pull-request to obtain a local copy using the GitHub CLI:
gh pr checkout PULL-REQUEST
Basic checks
To ensure the highest possible standard and uniformity of the data set implementations, please check the following dataset requirements.
- The dataset should be implemented in
bigbio/hub/hub_repos/<dataset>and contain (at least) the three default files<dataset>.py,bigbiohub.pyandREADME.md. - Check whether all data set meta-data are given in
<dataset>.pyandREADME.md. Refer to BC5CDR for an example of a complete set of information. - The dataset should not import
bigbiobut instead use.bigbiohub.
Run unit tests
Run the following command from the top level of the biomedical repo (i.e. the same directory that contains the requirements.txt file).
Check if the new or updated dataloader satisfies our unit tests as follows by using this command in the terminal:
python -m tests.test_bigbio_hub <dataset_name> [--data_dir /path/to/local/data] --test_local
Note, you MUST include the --test_local flag to specifically test the script for your PR, otherwise
the script will default to downloading a dataloader script from the Hub. Your particular dataset may
require use of some of the other command line args in the test script (ex: --data_dir for dataloaders
that read local files).
<br>
To view full usage instructions you can use the --help command:
python -m tests.test_bigbio --help
This will explain the types of arguments you may need to test for. A brief annotation is as such:
dataset_name: Name of the dataset you want to testdata_dir: The location of the data for datasets whereLOCAL_ = Trueconfig_name: Name of the configuration you want to test. By default, the script will test all configs, but if you can use this to debug a specific split, or if your data is prohibitively large.ishub: Use this when unit testing scripts that are not yet uploaded to the hub (this is True for most cases)
If any (severe) errors occur, report these to the PR author.
Update hub dataset
Finally, the data set needs to be updated in the BigBio Huggingface datasets hub.
Note that this step should be performed just before merging the PR, as uploading to the hub might fail due to errors in the README / dataset card that the PR author can still fix.
For this, first create or retrieve an API access token of your huggingface account:
https://huggingface.co/settings/tokens
Note to create a token with write access:

Run the following command from the top-level of the repository to update the data set in the hub:
HUGGING_FACE_HUB_TOKEN=<ACCESS-TOKEN> python bigbio/hub/upload.py <dataset>
If the PR is concerned with a completely new data set add the option -c for creating a new data
set repo in the hub first:
HUGGING_FACE_HUB_TOKEN=<ACCESS-TOKEN> python bigbio/hub/upload.py <dataset> -c
Moreover, you can test your upload command by first running a dry-run using option -d:
HUGGING_FACE_HUB_TOKEN=<ACCESS-TOKEN> python bigbio/hub/upload.py <dataset> -d
After running the command, visit hub webpage of the data set and check if the model card and the data viewer are displayed and the files are updated correctly, e.g. https://huggingface.co/datasets/bigbio/bc5cdr
Merge the PR
If all previous checks could be performed successfully merge the PR into main branch:
gh pr merge PULL-REQUEST
What's inside
5 sequential steps: checkout, basic checks, unit tests, hub upload, merge. Includes 6 code blocks and 1 screenshot reference.
Change this for your project
- Replace
bigbio/hub/hub_repos/<dataset>with your own dataset directory path - Replace
bigbioreferences (e.g.,bigbio/hub/upload.py,tests.test_bigbio_hub) with your own module names - Replace
HUGGING_FACE_HUB_TOKEN=<ACCESS-TOKEN>with your actual token - Replace
PULL-REQUESTwith the actual PR number
Where it goes
Keep it in your repository where the agent or team that needs it will read it.
Worth borrowing
- Separates hub upload into dry-run, create-new, and update commands with distinct flags
- Uses a checklist of three required files per dataset to enforce uniformity
