Selecting embedding size in BedrockEmbedding titan v1 and v2, switching dimensions dynamically via keyword arguments using langchain

Question

I am trying to provide dimension argument while trying to fetch the Titan version 1 and version 2 embedding models, but the BedrockEmbedding class does not have the feature of dimension, It only provideds the default 1024 dimension. How can we solve this?

Below is how i am calling BedrockEmbedding from langchain_community.embeddings import BedrockEmbeddings

Below is how i am calling BedrockEmbedding
from langchain_community.embeddings import BedrockEmbeddings

Hi,

You don't have to provide the embeddings dimensions in the query: the model that you select (via its id) will return the number of dimensions that it is programmed for.

So, if you work with multiple embedding engines, your code must be ready to work with variable numbers of dimensions depending on the model that you query.

Best,

Didier
