Kernels CLI Reference

Main Functions

kernels check

You can use kernels check to test compliance of a kernel on the Hub. This currently checks that the kernel:

• Supports the currently-required Python ABI version.
• Works on supported operating system versions.

For example:

$ kernels check kernels-community/flash-attn3
Checking variant: torch28-cxx11-cu128-aarch64-linux
  🐍 Python ABI 3.9 compatible
  🐧 manylinux_2_28 compatible
[...]

kernels upload

Use kernels upload <dir_containing_build> --repo_id="hub-username/kernel" to upload your kernel builds to the Hub. To know the supported arguments run: kernels upload -h.

Notes:

• This will take care of creating a repository on the Hub with the repo_id provided.
• If a repo with the repo_id already exists and if it contains a build with the build variant being uploaded, it will attempt to delete the files existing under it.
• Make sure to be authenticated (run hf auth login if not) to be able to perform uploads to the Hub.
