kkt is a tool for kaggle kernel management.

Actions Status PyPI PythonVersions


  • Show the status of the latest version
  • Push your script or notebook to the Kaggle Kernels
  • Pack and emmbedded your library codes into the generated bootstrap codes
  • Create a dataset containing your dependent packages
  • Add bootstrap codes into the head of your script or notebook automatically
  • Add git tags whose name is corresponding kernel version
  • Set environment variable for your kernels


For now, kkt is designed to be used with poetry. So kkt can be installed by the following.

$ poetry add kkt --dev


Set username and token of kaggle-api

Please setup your kaggle-api credentials as following this article

Setup kkt in your project

Setup this project for digit-recognizer competition. In this configuration, we use script.py. If you want to use notebook, kkt also support it.

$ poetry run kkt init
Appending Kkt section into your pyproject.toml config.
competition: digit
0 digit-recognizer
> 0
slug: kkt-example
code_file [script.py]: script.py
kernel_type [script]: script
is_private [Y/n]: n
enable_gpu [y/N]: n
enable_internet [y/N]: y
Would you like to add dataset sources? [y/N]: n
enable_git_tag [y/N]: n

Create kkt_example package and its driver code.

kkt_example provides random choice solver for digit-recognizer competition.

If you want run script.py in local environmet, please run the following.

Create a dataset containing dependent packages if need

In this example, there aren't extra required packages. So kkt install displays the following. And this step is not mandatory.

$ poetry run kkt install
ref: /ar90ngas/kkt-example-install
url: https://www.kaggle.com/ar90ngas/kkt-example-install
version: 1
Pushing install kernel successed.

Extra required packages are nothing.

But in the little complicated project such as mnist_efficientnet example, kkt install displays the following. This means that a new dataset whose slug is ar90ngas/mnist-efficientnet-requirements is created. And it contains an extra package which is required by this example. And this package will be installed automatically in the bootstrap code.

$ poetry run kkt install
ref: /ar90ngas/mnist-efficientnet-install
url: https://www.kaggle.com/ar90ngas/mnist-efficientnet-install
version: 1
