Llama Stack is composed of several APIs working together. Let's select
the provider types (implementations) you want to use for these APIs.

Tip: use <TAB> to see options for the providers.

> Enter provider for API inference: remote::openai
> Enter provider for API safety: inline::llama-guard
> Enter provider for API agents: inline::meta-reference
> Enter provider for API vector_io: inline::meta-reference
> Enter provider for API datasetio: inline::localfs
> Enter provider for API scoring: inline::basic
> Enter provider for API eval: inline::meta-reference
> Enter provider for API post_training: inline::torchtune
> Enter provider for API tool_runtime: remote::model-context-protocol
> Enter provider for API telemetry: inline::meta-reference
 
 > (Optional) Enter a short description for your Llama Stack:
Using virtual environment llamastack-stack
Using CPython 3.9.21 interpreter at: /usr/bin/python3.9
Creating virtual environment at: llamastack-stack
Activate with: source llamastack-stack/bin/activate
Using Python 3.9.21 environment at: llamastack-stack
  × No solution found when resolving dependencies:
  ╰─▶ Because the current Python version (3.9.21) does not satisfy Python>=3.10 and all versions of llama-stack depend on Python>=3.10, we can conclude that all versions of llama-stack cannot be used.
      And because you require llama-stack, we can conclude that your requirements are unsatisfiable.
