## Usage

To utilize a vector database, you must provide a configuration to customize its usage. If no configuration is supplied, a default configuration will be applied, and `Qdrant` will be used as the vector database.

For a comprehensive list of available parameters for vector database configuration, please refer to [Config](./config).

## Common issues
|
|
|
|
### Using model with different dimensions
|
|
|
|
If you are using customized model, which is having different dimensions other than 1536
|
|
for example 768, you may encounter below error:
|
|
|
|
`ValueError: shapes (0,1536) and (768,) not aligned: 1536 (dim 1) != 768 (dim 0)`
|
|
|
|
you could add `"embedding_model_dims": 768,` to the config of the vector_store to overcome this issue.
