### Launch the cli via pip install
```bash
pip install infinity-emb[all]
```
After your pip install, with your venv active, you can run the CLI directly.

```bash
infinity_emb v2 --model-id BAAI/bge-small-en-v1.5
```
Check the `v2 --help` command to get a description for all parameters.
```bash
infinity_emb v2 --help
```

---

### Launch the CLI using a pre-built docker container (recommended)
Instead of installing the CLI via pip, you may also use docker to run `michaelf34/infinity`. 
Make sure you mount your accelerator ( i.e. install `nvidia-docker` and activate with `--gpus all`). 

```bash
port=7997
model1=michaelfeil/bge-small-en-v1.5
model2=mixedbread-ai/mxbai-rerank-xsmall-v1
volume=$PWD/data

docker run -it --gpus all \
 -v $volume:/app/.cache \
 -p $port:$port \
 michaelf34/infinity:latest \
 v2 \
 --model-id $model1 \
 --model-id $model2 \
 --port $port
```
The cache path inside the docker container is set by the environment variable `HF_HOME`.

#### Specialized docker images
<details>
  <summary>Docker container for CPU</summary>
  Use the `latest-cpu` image or `x.x.x-cpu` for slimer image. 
  Run like any other cpu-only docker image. 
  Optimum/Onnx is often the prefered engine. 

  ```
  docker run -it \
  -v $volume:/app/.cache \
  -p $port:$port \
  michaelf34/infinity:latest-cpu \
  v2 \
  --engine optimum \
  --model-id $model1 \
  --model-id $model2 \
  --port $port
  ```
</details>

<details>
  <summary>Docker Container for ROCm (MI200 Series and MI300 Series)</summary>
  Use the `latest-rocm` image or `x.x.x-rocm` for rocm compatible inference.
  **This image is currently not build via CI/CD (to large), consider pinning to exact version.**
  Make sure you have ROCm is correctly installed and ready to use with Docker.

  Visit [Docs](https://michaelfeil.github.io/infinity) for more info.
</details>
 
<details>
  <summary>Docker Container for Onnx-GPU, Cuda Extensions, TensorRT</summary>
  Use the `latest-trt-onnx` image or `x.x.x-trt-onnx` for nvidia compatible inference.
  **This image is currently not build via CI/CD (to large), consider pinning to exact version.**

  This image has support for:
  - ONNX-Cuda "CudaExecutionProvider" 
  - ONNX-TensorRT "TensorRTExecutionProvider" (may not always work due to version mismatch with ORT)
  - CudaExtensions and packages, e.g. Tri-Dao's `pip install flash-attn` package when using Pytorch.
  - nvcc compiler support
  
  ```
  docker run -it \
  -v $volume:/app/.cache \
  -p $port:$port \
  michaelf34/infinity:latest-trt-onnx \
  v2 \
  --engine optimum \
  --device cuda \
  --model-id $model1 \
  --port $port
  ```
</details>

#### Using local models with Docker container

In order to deploy a local model with a docker container, you need to mount the model inside the container and specify the path in the container to the launch command.

Example:
```bash
git lfs install 
cd /tmp
mkdir models && cd models && git clone https://huggingface.co/BAAI/bge-small-en-v1.5
docker run -it   -v /tmp/models:/models  -p 8081:8081  michaelf34/infinity:latest v2  --model-id "/models/bge-small-en-v1.5" --port 8081
```

#### Advanced CLI usage

<details>
  <summary>Launching multiple models at once</summary>
  
  Since `infinity_emb>=0.0.34`, you can use cli `v2` method to launch multiple models at the same time.
  Checkout `infinity_emb v2 --help` for all args and validation.

  Multiple Model CLI Playbook:                                                                                         
   - 1. cli options can be repeated e.g. `v2 --model-id model/id1 --model-id model/id2 --batch-size 8 --batch-size 4`. This will create two models `model/id1` and `model/id2`
   - 2. or adapt the defaults by setting ENV Variables separated by `;`: `INFINITY_MODEL_ID="model/id1;model/id2;" && INFINITY_BATCH_SIZE="8;4;"`
   - 3. single items are broadcasted to `--model-id` length,  `v2 --model-id model/id1 --model-id/id2 --batch-size 8` making both models have batch-size 8.
   - 4. Everythin
