Chroma and LlamaIndex both offer embedding functions which are wrappers on top of popular embedding models. Unfortunately Chroma and LI's embedding functions are not compatible with each other. Below we offer an adapters to convert LI embedding function to Chroma one.

from llama_index.embeddings.base import BaseEmbedding
import chromadb
from chromadb.api.types import EmbeddingFunction
class LlamaIndexEmbeddingAdapter(EmbeddingFunction):
def __init__(self,ef:BaseEmbedding):
self.ef = ef
def __call__(self, input: Documents) -> Embeddings:

Created August 15, 2023 13:44
This gist illustrates how to store vectors of your documents in chroma without providing your actual text documents. Useful if your docs contain sensitive info or you are mindful of the storage.
import uuid
from chromadb.utils import embedding_functions
import chromadb
ef = embedding_functions.DefaultEmbeddingFunction()
docs = ["Article by john", "Article by Jack", "Article by Jill"]
client = chromadb.Client()
embeddings = ef(docs)
collection = client.get_or_create_collection("test-where-list")

The Downsides of LLMs (Logical Language Models)
In the age of artificial intelligence, Logical Language Models (LLMs) represent a significant leap forward in the field of natural language processing. These models are capable of comprehending, generating, and reasoning about human languages in a way that mimics human-like understanding. While the benefits of LLMs are numerous, it's essential to also recognize the downsides that accompany these advancements. This essay will explore the negative aspects of LLMs in terms of ethics, job displacement, security, and potential biases.
