||||
`llama-cpp-python` supports such as llava1.5 which allow the language model to read information from both text and images.
|
||||

You'll first need to download one of the available multi-modal models in GGUF format:
|
||||
|
||||
- [llava-v1.5-7b](https://huggingface.co/mys/ggml_llava-v1.5-7b)
|
||||
- [llava-v1.5-13b](https://huggingface.co/mys/ggml_llava-v1.5-13b)

|
||||
- [moondream2](https://huggingface.co/vikhyatk/moondream2)
|
||||
|
||||
Then you'll need to use a custom chat handler to load the clip model and process the chat messages and images.
|
||||
|
||||
```python
|
||||
>>> from llama_cpp import Llama
|
||||
>>> from llama_cpp.llama_chat_format import Llava15ChatHandler
|

llm.create_chat_completion(

### Embeddings
|

To generate text embeddings use [`create_embedding`](https://llama-cpp-python.readthedocs.io/en/latest/api-reference/#llama_cpp.Llama.create_embedding).
|
||||
To generate text embeddings use [`create_embedding`](https://llama-cpp-python.readthedocs.io/en/latest/api-reference/#llama_cpp.Llama.create_embedding) or [`embed`](https://llama-cpp-python.readthedocs.io/en/latest/api-reference/#llama_cpp.Llama.embed). Note that you must pass `embedding=True` to the constructor upon model creation for these to work properly.
|
||||
|
||||
```python
|
||||
import llama_cpp
|
||||
|
|
@ -589,6 +633,12 @@ embeddings = llm.create_embedding("Hello, world!")
|
|||
embeddings = llm.create_embedding(["Hello, world!", "Goodbye, world!"])
|
||||
```
|
||||
|
||||
There are two primary notions of embeddings in a Transformer-style model: *token level* and *sequence level*. Sequence level embeddings are produced by "pooling" token level embeddings together, usually by averaging them or using the first token.
|
||||
|
||||
Models that are explicitly geared towards embeddings will usually return sequence level embeddings by default, one for each input string. Non-embedding models such as those designed for text generation will typically return only token level embeddings, one for each token in each sequence. Thus the dimensionality of the return type will be one higher for token level embeddings.
|
||||
|
||||
It is possible to control pooling behavior in some cases using the `pooling_type` flag on model creation. You can ensure token level embeddings from any model using `LLAMA_POOLING_TYPE_NONE`. The reverse, getting a generation oriented model to yield sequence level embeddings is currently not possible, but you can always do the pooling manually.
|
||||
|
||||
### Adjusting the Context Window
|
||||
|
||||
The context window of the Llama models determines the maximum number of tokens that can be processed at once. By default, this is set to 512 tokens, but can be adjusted based on your requirements.
