Beta Release

Please be advised that our service is currently in its beta release of development. As a beta user, your feedback and suggestions are highly valuable in helping us identify and address any issues. We kindly request your patience and understanding as we work diligently to enhance the service based on your input.

Test your NRP

Prior to deployment on the Neurolibre server, it is crucial to thoroughly test your submission locally to prevent potential issues. Here are the essential steps to ensure a smooth deployment:

  • Verify Local Notebook Execution:

Test all the notebooks locally, ensuring they run seamlessly with the specified hardware requirements mentioned in the computation and data section.

  • Validate Jupyter Book Build:

Locally build the Jupyter book without relying on cache files to ensure it compiles successfully. By meticulously testing your submission locally, you can preemptively address any problems and guarantee a reliable deployment experience on the Neurolibre server. This proactive approach will save time and ensure a smoother integration into the platform.

  • Test your NRP on RoboNeuro

We provide a web service to test your NRP builds using the same infrastructure involved in the technical screening process.

Quick guide for local testing

With the necessary dependencies already installed for local notebook development and your preprint repository structured according to the Structure your NRP repository, conducting a local test of your preprint build becomes a straightforward process.

Install Jupyter Book (prefer <= 0.14.0)

pip install jupyter-book

Describe your data dependencies

Given the following minimalistic repository structure:

├── binder
│   ├── requirements.txt
│   └── data_requirement.json
├── content
│   ├── _build
│   ├── notebook.ipynb
│   ├── _config.ym
│   └── _toc.yml

Create a folder named data at the root of the repository and don’t forget to add it to the .gitignore file to exclude it from version control:

Install Repo2Data:

pip install repo2data

Configure the dst from the requirement file (binder/data_requirement.json), so it points to the data folder you created:

{"src" : "/url/to/the/online/source",
 "dst" : "../data",
 "projectName": "my_dataset"}

Run repo2data inside your notebook and get the path to the data.

Build your Jupyter Book

cd /your/repo/directory
jupyter-book build ./content

Please visit reference documentation on executing and caching your outputs during a book build.

See also: GitHub Actions to test book builds

You can take a look at this example GitHub Actions file to see how you can trigger a book build whenever a commit is pushed to the main branch of your NRP repository.

Please be aware that the GitHub Actions workflow’s necessary steps may vary depending on your specific requirements. It’s essential to adapt the workflow accordingly to suit your NRP’s needs.

Testing on NeuroLibre servers

We are thrilled to present 🤖 RoboNeuro 🤖, our dedicated preprint submission bot, designed to assist you in effortlessly creating NeuroLibre preprints anytime you need. With RoboNeuro at your service round the clock, preprint submission becomes a breeze!

This service allows you to evaluate whether your submission meets specific requirements before formal submission. It helps ensure that all contributions align with our guidelines and standards.

Using the RoboNeuro preview service is a straightforward process:

  1. Access the service at

  2. Provide the URL of your public GitHub repository.

  3. Enter your email address and the GitHub commit SHA for the build.

  4. Wait for the service to process your request and send you the results via email.

By leveraging the RoboNeuro preview service, we aim to enhance the quality and consistency of submitted preprints. It serves as a valuable tool for authors, allowing them to verify that their work aligns with the necessary criteria before proceeding with the formal submission process.


The RoboNeuro book build process comprises two distinct stages:

  • Firstly, it establishes a virtual environment based on your specified runtime descriptions (runtime build).

  • Upon successful completion of this stage, it proceeds to the second phase, where it builds the Jupyter Book by re-executing your code within that environment (book build).

🌱 On a successful book build, we will return you a URL that serves your NRP at the provided commit SHA from which it was built.

🥀 If the build fails, we will send you an html file that contains the following logs:
  • Binder build logs

  • Book build logs

  • Execution logs of individual notebooks

A successful book build on RoboNeuro preview service makes technical screening easier.

Please note that RoboNeuro book preview is provided as a public service with limited computational resources. Therefore we encourage you to build your book locally before using

Debugging a long-running book build

We offer, a Binder build page, where you can initiate a runtime build. By default, if the runtime build succeeds, it automatically proceeds to perform a book build.

However, if the execution of all your notebooks take considerably long time (say more than 20 minutes), you may want to bypass the book build phase to debug a particular notebook in the runtime environment built on our test BinderHub. This is particularly useful in cases where the Jupyter book build fails on Neurolibre but works locally.

To bypass the book build, simply include --neurolibre-debug in your latest commit message, as demonstrated in this git commit. Upon a successful runtime build, you can interact with your NeuroLibre Research Preprint (NRP) through the Jupyter Notebook interface in your web browser. This interface allows you to execute code cells in specific notebooks or run commands in the terminal as needed.


If you run into out of memory errors on Neurolibre, you can reduce the RAM requirements on the interactive session, and try to re-run the jupyter book build in the same session.

Do not forget to remove the debug flag

Once you have finished debugging your executable content on, make sure that your latest commit does not have the --neurolibre-debug in its commit message. Otherwise, following requests will not trigger a book build.
