Kaggle Notebooks allow users to run a Python Notebook in the cloud against our competitions and datasets without having to download data or set up their environment.

This repository includes theDockerfile for building the CPU-only and GPU image that runs Python Notebooks on Kaggle.

Our Python Docker images are stored on the Google Container Registry at:

• CPU-only:gcr.io/kaggle-images/python
• GPU:gcr.io/kaggle-gpu-images/python

First, evaluate whether installing the package yourself in your own notebooks suits your needs. Seeguide.

If you the first step above doesn't work for your use case,open an issue or apull request.

1. Editkaggle_requirements.txt.
2. Follow the instructions below to build a new image.
3. Add tests for your new package. See thisexample.
4. Follow the instructions below to test the new image.
5. Open a PR on this repo and you are all set!

./build

Flags:

• --gpu to build an image for GPU.
• --use-cache for faster iterative builds.

A suite of tests can be found under the/tests folder. You can run the test using this command:

./test

Flags:

• --gpu to test the GPU image.
• --pattern test_keras.py or-p test_keras.py to run a single test
• --image gcr.io/kaggle-images/python:ci-pretest or-i gcr.io/kaggle-images/python:ci-pretest to test against a specific image

For the CPU-only image:

# Run the image built locally:docker run --rm -it kaggle/python-build /bin/bash# Run the pre-built image from gcr.iodocker run --rm -it gcr.io/kaggle-images/python /bin/bash

For the GPU image:

# Run the image built locally:docker run --runtime nvidia --rm -it kaggle/python-gpu-build /bin/bash# Run the image pre-built image from gcr.iodocker run --runtime nvidia --rm -it gcr.io/kaggle-gpu-images/python /bin/bash

To ensure your container can access the GPU, follow the instructions postedhere.
