## Installation and Setup
|
||
|
|
|
||
|
|
We need to install `scann` python package.
|
||
|
|
|
||
|
|
```bash
|
||
|
|
pip install scann
|
||
|
|
```
|
||
|
|
|
||
|
|
## Vector Store
|
||
|
|
|
||
|
|
See a [usage example](/docs/integrations/vectorstores/scann).
|
||
|
|
|
||
|
|
```python
|
||
|
|
from langchain.vectorstores import ScaNN
|
||
|
|
```
|
