AdapterHub CLI

The AdapterHub CLI provides command-line tools to help you contributing to the Hub, such as packaging adapters or validating filled-out yaml files.

To install the CLI from the cloned repository, you can run the following in this folder:

pip install -U ./scripts/.

Alternatively, you can install the CLI using:

pip install -U git+

Now you can use the pack pack command to interactively prepare your adapters for upload and submission to the Hub:

adapter-hub-cli pack <folder_with_models_or_adapters>

To validate yaml files, run:

adapter-hub-cli check path/to/adapter.yaml

Read more about the AdapterHub CLI in the documentation.
