# Meta Reference Distribution
|
||||
|
||||
The `llamastack/distribution-meta-reference-gpu` distribution consists of the following provider configurations.
|
||||
|
||||
|
||||
| **API** | **Inference** | **Agents** | **Memory** | **Safety** | **Telemetry** |
|
||||
|----------------- |--------------- |---------------- |-------------------------------------------------- |---------------- |---------------- |
|
||||
| **Provider(s)** | meta-reference | meta-reference | meta-reference, remote::pgvector, remote::chroma | meta-reference | meta-reference |
|
||||
|
||||
|
||||
### Start the Distribution (Single Node GPU)
|
||||
|
||||
```
|
||||
$ cd distributions/meta-reference-gpu
|
||||
$ ls
|
||||
build.yaml compose.yaml README.md run.yaml
|
||||
$ docker compose up
|
||||
```
|
||||
|
||||
> [!NOTE]
|
||||
> This assumes you have access to GPU to start a local server with access to your GPU.
|
||||
|
||||
|
||||
> [!NOTE]
|
||||
> `~/.llama` should be the path containing downloaded weights of Llama models.
|
||||
|
||||
|
||||
This will download and start running a pre-built docker container. Alternatively, you may use the following commands:
|
||||
|
||||
```
|
||||
docker run -it -p 5000:5000 -v ~/.llama:/root/.llama -v ./run.yaml:/root/my-run.yaml --gpus=all distribution-meta-reference-gpu --yaml_config /root/my-run.yaml
|
||||
```
|
||||
|
||||
### Alternative (Build and start distribution locally via conda)
|
||||
- You may checkout the [Getting Started](../../docs/getting_started.md) for more details on building locally via conda and starting up a meta-reference distribution.
|
||||
|
||||
### Start Distribution With pgvector/chromadb Memory Provider
|
||||
##### pgvector
|
||||
1. Start running the pgvector server:
|
||||
|
||||
```
|
||||
docker run --network host --name mypostgres -it -p 5432:5432 -e POSTGRES_PASSWORD=mysecretpassword -e POSTGRES_USER=postgres -e POSTGRES_DB=postgres pgvector/pgvector:pg16
|
||||
```
|
||||
|
||||
2. Edit the `run.yaml` file to point to the pgvector server.
|
||||
```
|
||||
memory:
|
||||
- provider_id: pgvector
|
||||
provider_type: remote::pgvector
|
||||
config:
|
||||
host: 127.0.0.1
|
||||
port: 5432
|
||||
db: postgres
|
||||
user: postgres
|
||||
password: mysecretpassword
|
||||
```
|
||||
|
||||
> [!NOTE]
|
||||
> If you get a `RuntimeError: Vector extension is not installed.`. You will need to run `CREATE EXTENSION IF NOT EXISTS vector;` to include the vector extension. E.g.
|
||||
|
||||
```
|
||||
docker exec -it mypostgres ./bin/psql -U postgres
|
||||
postgres=# CREATE EXTENSION IF NOT EXISTS vector;
|
||||
postgres=# SELECT extname from pg_extension;
|
||||
extname
|
||||
```
|
||||
|
||||
3. Run `docker compose up` with the updated `run.yaml` file.
|
||||
|
||||
##### chromadb
|
||||
1. Start running chromadb server
|
||||
```
|
||||
docker run -it --network host --name chromadb -p 6000:6000 -v ./chroma_vdb:/chroma/chroma -e IS_PERSISTENT=TRUE chromadb/chroma:latest
|
||||
```
|
||||
|
||||
2. Edit the `run.yaml` file to point to the chromadb server.
|
||||
```
|
||||
memory:
|
||||
- provider_id: remote::chromadb
|
||||
provider_type: remote::chromadb
|
||||
config:
|
||||
host: localhost
|
||||
port: 6000
|
||||
```
|
||||
|
||||
3. Run `docker compose up` with the updated `run.yaml` file.
|
||||
|
||||
### Serving a new model
|
||||
You may change the `config.model` in `run.yaml` to update the model currently being served by the distribution. Make sure you have the model checkpoint downloaded in your `~/.llama`.
|
||||
```
|
||||
inference:
|
||||
- provider_id: meta0
|
||||
provider_type: meta-reference
|
||||
config:
|
||||
model: Llama3.2-11B-Vision-Instruct
|
||||
quantization: null
|
||||
torch_seed: null
|
||||
max_seq_len: 4096
|
||||
max_batch_size: 1
|
||||
```
|
||||
|
||||
Run `llama model list` to see the available models to download, and `llama model download` to download the checkpoints.
