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.
