- -To download models, you can use the llama download command. - -#### Downloading from [Meta](https://llama.meta.com/llama-downloads/) - -Here is an example download command to get the 3B-Instruct/11B-Vision-Instruct model. You will need META_URL which can be obtained from [here](https://llama.meta.com/docs/getting_the_models/meta/) - -Download the required checkpoints using the following commands: -```bash -# download the 8B model, this can be run on a single GPU -llama download --source meta --model-id Llama3.2-3B-Instruct --meta-url META_URL - -# you can also get the 70B model, this will require 8 GPUs however -llama download --source meta --model-id Llama3.2-11B-Vision-Instruct --meta-url META_URL - -# llama-agents have safety enabled by default. For this, you will need -# safety models -- Llama-Guard and Prompt-Guard -llama download --source meta --model-id Prompt-Guard-86M --meta-url META_URL -llama download --source meta --model-id Llama-Guard-3-1B --meta-url META_URL -``` - -#### Downloading from [Hugging Face](https://huggingface.co/meta-llama) - -Essentially, the same commands above work, just replace `--source meta` with `--source huggingface`. - -```bash -llama download --source huggingface --model-id Llama3.1-8B-Instruct --hf-token - -llama download --source huggingface --model-id Llama3.1-70B-Instruct --hf-token - -llama download --source huggingface --model-id Llama-Guard-3-1B --ignore-patterns *original* -llama download --source huggingface --model-id Prompt-Guard-86M --ignore-patterns *original* -``` - -**Important:** Set your environment variable `HF_TOKEN` or pass in `--hf-token` to the command to validate your access. You can find your token at [https://huggingface.co/settings/tokens](https://huggingface.co/settings/tokens). - -> **Tip:** Default for `llama download` is to run with `--ignore-patterns *.safetensors` since we use the `.pth` files in the `original` folder. For Llama Guard and Prompt Guard, however, we need safetensors. Hence, please run with `--ignore-patterns original` so that safetensors are downloaded and `.pth` files are ignored. - -#### Downloading via Ollama - -If you're already using ollama, we also have a supported Llama Stack distribution `local-ollama` and you can continue to use ollama for managing model downloads. - -``` -ollama pull llama3.1:8b-instruct-fp16 -ollama pull llama3.1:70b-instruct-fp16 -``` - -> [!NOTE] -> Only the above two models are currently supported by Ollama. - - -## Step 2: Understand the models -The `llama model` command helps you explore the model’s interface. - -### 2.1 Subcommands -1. `download`: Download the model from different sources. (meta, huggingface) -2. `list`: Lists all the models available for download with hardware requirements to deploy the models. -3. `prompt-format`: Show llama model message formats. -4. `describe`: Describes all the properties of the model. - -### 2.2 Sample Usage - -`llama model ` - -``` -llama model --help -``` -

We will name our build `tgi` to help us remember the config. We will start build our distribution (in the form of a Conda environment, or Docker image). In this step, we will specify: -- `name`: the name for our distribution (e.g. `tgi`) -- `image_type`: our build image type (`conda | docker`) -- `distribution_spec`: our distribution specs for specifying API providers - - `description`: a short description of the configurations for the distribution - - `providers`: specifies the underlying implementation for serving each API endpoint - - `image_type`: `conda` | `docker` to specify whether to build the distribution in the form of Docker image or Conda environment. - - -At the end of build command, we will generate `-build.yaml` file storing the build configurations. - -After this step is complete, a file named `-build.yaml` will be generated and saved at the output file path specified at the end of the command. - -#### Building from scratch -- For a new user, we could start off with running `llama stack build` which will allow you to a interactively enter wizard where you will be prompted to enter build configurations. -``` -llama stack build -``` - -Running the command above will allow you to fill in the configuration to build your Llama Stack distribution, you will see the following outputs. - -``` -> Enter an unique name for identifying your Llama Stack build distribution (e.g. my-local-stack): my-local-llama-stack -> Enter the image type you want your distribution to be built with (docker or conda): conda - - Llama Stack is composed of several APIs working together.

- -To download models, you can use the llama download command. - -### Downloading from [Meta](https://llama.meta.com/llama-downloads/) - -Here is an example download command to get the 3B-Instruct/11B-Vision-Instruct model. You will need META_URL which can be obtained from [here](https://llama.meta.com/docs/getting_the_models/meta/) - -Download the required checkpoints using the following commands: -```bash -# download the 8B model, this can be run on a single GPU -llama download --source meta --model-id Llama3.2-3B-Instruct --meta-url META_URL - -# you can also get the 70B model, this will require 8 GPUs however -llama download --source meta --model-id Llama3.2-11B-Vision-Instruct --meta-url META_URL - -# llama-agents have safety enabled by default. For this, you will need -# safety models -- Llama-Guard and Prompt-Guard -llama download --source meta --model-id Prompt-Guard-86M --meta-url META_URL -llama download --source meta --model-id Llama-Guard-3-1B --meta-url META_URL -``` - -### Downloading from [Hugging Face](https://huggingface.co/meta-llama) - -Essentially, the same commands above work, just replace `--source meta` with `--source huggingface`. - -```bash -llama download --source huggingface --model-id Llama3.1-8B-Instruct --hf-token - -llama download --source huggingface --model-id Llama3.1-70B-Instruct --hf-token - -llama download --source huggingface --model-id Llama-Guard-3-1B --ignore-patterns *original* -llama download --source huggingface --model-id Prompt-Guard-86M --ignore-patterns *original* -``` - -**Important:** Set your environment variable `HF_TOKEN` or pass in `--hf-token` to the command to validate your access. You can find your token at [https://huggingface.co/settings/tokens](https://huggingface.co/settings/tokens). - -> **Tip:** Default for `llama download` is to run with `--ignore-patterns *.safetensors` since we use the `.pth` files in the `original` folder. For Llama Guard and Prompt Guard, however, we need safetensors. Hence, please run with `--ignore-patterns original` so that safetensors are downloaded and `.pth` files are ignored. - -### Downloading via Ollama - -If you're already using ollama, we also have a supported Llama Stack distribution `local-ollama` and you can continue to use ollama for managing model downloads. - -``` -ollama pull llama3.1:8b-instruct-fp16 -ollama pull llama3.1:70b-instruct-fp16 -``` - -> [!NOTE] -> Only the above two models are currently supported by Ollama. - - -## Step 2: Understand the models -The `llama model` command helps you explore the model’s interface. - -### 2.1 Subcommands -1. `download`: Download the model from different sources. (meta, huggingface) -2. `list`: Lists all the models available for download with hardware requirements to deploy the models. -3. `prompt-format`: Show llama model message formats. -4. `describe`: Describes all the properties of the model. - -### 2.2 Sample Usage - -`llama model ` - -``` -llama model --help -``` -
-usage: llama model [-h] {download,list,prompt-format,describe} ...
-
-Work with llama models

We will name our build `8b-instruct` to help us remember the config. We will start build our distribution (in the form of a Conda environment, or Docker image). In this step, we will specify: -- `name`: the name for our distribution (e.g. `8b-instruct`) -- `image_type`: our build image type (`conda | docker`) -- `distribution_spec`: our distribution specs for specifying API providers - - `description`: a short description of the configurations for the distribution - - `providers`: specifies the underlying implementation for serving each API endpoint - - `image_type`: `conda` | `docker` to specify whether to build the distribution in the form of Docker image or Conda environment. - - -At the end of build command, we will generate `-build.yaml` file storing the build configurations. - -After this step is complete, a file named `-build.yaml` will be generated and saved at the output file path specified at the end of the command. - -#### Building from scratch -- For a new user, we could start off with running `llama stack build` which will allow you to a interactively enter wizard where you will be prompted to enter build configurations. -``` -llama stack build -``` - -Running the command above will allow you to fill in the configuration to build your Llama Stack distribution, you will see the following outputs. - -``` -> Enter an unique name for identifying your Llama Stack build distribution (e.g. my-local-stack): my-local-llama-stack -> Enter the image type you want your distribution to be built with (docker or conda): conda - - Llama Stack is composed of several APIs working together.

You can even imagine moving across the server / mobile-device boundary as well always using the same uniform set of APIs for developing Generative AI applications. diff --git a/docs/source/getting_started.md b/docs/source/getting_started.md deleted file mode 100644 index b1450cd42..000000000 --- a/docs/source/getting_started.md +++ /dev/null @@ -1,429 +0,0 @@ -# Getting Started - -This guide will walk you though the steps to get started on end-to-end flow for LlamaStack.

We will start build our distribution (in the form of a Conda environment, or Docker image). In this step, we will specify: -- `name`: the name for our distribution (e.g. `8b-instruct`) -- `image_type`: our build image type (`conda | docker`) -- `distribution_spec`: our distribution specs for specifying API providers - - `description`: a short description of the configurations for the distribution - - `providers`: specifies the underlying implementation for serving each API endpoint - - `image_type`: `conda` | `docker` to specify whether to build the distribution in the form of Docker image or Conda environment. - - -At the end of build command, we will generate `-build.yaml` file storing the build configurations. - -After this step is complete, a file named `-build.yaml` will be generated and saved at the output file path specified at the end of the command. - -#### Building from scratch -- For a new user, we could start off with running `llama stack build` which will allow you to a interactively enter wizard where you will be prompted to enter build configurations. -``` -llama stack build -``` - -Running the command above will allow you to fill in the configuration to build your Llama Stack distribution, you will see the following outputs. - -``` -> Enter an unique name for identifying your Llama Stack build distribution (e.g. my-local-stack): 8b-instruct -> Enter the image type you want your distribution to be built with (docker or conda): conda - - Llama Stack is composed of several APIs working together.

be used to quickly and reliably build an app. We need a testing setup which is relatively flexible to enable easy combinations of these providers. + +We use `pytest` and all of its dynamism to enable the features needed. Specifically: + +- We use `pytest_addoption` to add CLI options allowing you to override providers, models, etc. + +- We use `pytest_generate_tests` to dynamically parametrize our tests. This allows us to support a default set of (providers, models, etc.) combinations but retain the flexibility to override them via the CLI if needed. + +- We use `pytest_configure` to make sure we dynamically add appropriate marks based on the fixtures we make. + +## Common options + +All tests support a `--providers` option which can be a string of the form `api1=provider_fixture1,api2=provider_fixture2`. So, when testing safety (which need inference and safety APIs) you can use `--providers inference=together,safety=meta_reference` to use these fixtures in concert. + +Depending on the API, there are custom options enabled. For example, `inference` tests allow for an `--inference-model` override, etc. + +By default, we disable warnings and enable short tracebacks. You can override them using pytest's flags as appropriate. + +Some providers need special API keys or other configuration options to work. You can check out the individual fixtures (located in `tests//fixtures.py`) for what these keys are. These can be specified using the `--env` CLI option. You can also have it be present in the environment (exporting in your shell) or put it in the `.env` file in the directory from which you run the test. For example, to use the Together fixture you can use `--env TOGETHER_API_KEY=<...>` + +## Inference + +We have the following orthogonal parametrizations (pytest "marks") for inference tests: +- providers: (meta_reference, together, fireworks, ollama) +- models: (llama_8b, llama_3b) + +If you want to run a test with the llama_8b model with fireworks, you can use: +```bash +pytest -s -v llama_stack/providers/tests/inference/test_inference.py \ + -m "fireworks and llama_8b" \ + --env FIREWORKS_API_KEY=<...> +``` + +You can make it more complex to run both llama_8b and llama_3b on Fireworks, but only llama_3b with Ollama: +```bash +pytest -s -v llama_stack/providers/tests/inference/test_inference.py \ + -m "fireworks or (ollama and llama_3b)" \ + --env FIREWORKS_API_KEY=<...> +``` + +Finally, you can override the model completely by doing: +```bash +pytest -s -v llama_stack/providers/tests/inference/test_inference.py \ + -m fireworks \ + --inference-model "Llama3.1-70B-Instruct" \ + --env FIREWORKS_API_KEY=<...> +``` + +## Agents + +The Agents API composes three other APIs underneath: +- Inference +- Safety +- Memory + +Given that each of these has several fixtures each, the set of combinations is large.
