### Features include - Metadata based embedding search - Choice of distance metric function (`L2` for Euclidean, `L1` for Nuclear, `max` L-infinity distance, `cos` for cosine similarity, 'dot' for dot product. Defaults to `L2` - Returning scores - Max Marginal Relevance Search - Deleting samples from the dataset ### Notes - Added numerous tests, let me know if you would like to shorten them or make smarter --------- Co-authored-by: Davit Buniatyan <d@activeloop.ai>

# Deep Lake
|
||
This page covers how to use the Deep Lake ecosystem within LangChain.
|
||
|
||
## Why Deep Lake?
|
||
- More than just a (multi-modal) vector store. You can later use the dataset to fine-tune your own LLM models.
|
||
- Not only stores embeddings, but also the original data with automatic version control.
|
||
- Truly serverless. Doesn't require another service and can be used with major cloud providers (AWS S3, GCS, etc.)

|
||
|
||
## Installation and Setup
|
||
- Install the Python package with `pip install deeplake`
|
||
|
||
## Wrappers
|
||
|
||
### VectorStore
|
||
|
||
There exists a wrapper around Deep Lake, a data lake for Deep Learning applications, allowing you to use it as a vector store (for now), whether for semantic search or example selection.
|
||
|
||
To import this vectorstore:
|
||
```python
|
||
from langchain.vectorstores import DeepLake
|
||
```
|
||
|
||
|
